'''Spike:''' Obnoxious little frog.
-->-- ''Anime/CowboyBebop''[[note]]who, in case you didn't know, [[TropeNamer named this trope]][[/note]]

Use of mind-altering substances distorts the world. Sometimes, the hallucinations are passed off as a side-effect of overconsumption of an [[ICantBelieveItsNotHeroin otherwise legal and legitimate foodstuff]] such as sugar, ice cream, chocolate, or steak sauce.

What makes this trope generally different from IntoxicationEnsues is the hallucinations. The narrative might jump back and forth between the hallucination and the real world to show they are holding a normal, intelligent conversation with a plant. Typically great comedic fodder with a believable setup. If it's animated, expect those affected to OpenTheIris.

If it doesn't contain AnAesop about the dangers of drug abuse with {{Anvilicious}} subtlety, it tends to just show off a character's carelessness. May involve a GRatedDrug. Hallucinations caused by alcohol go under the subtrope PinkElephants. See AcidRefluxNightmare for a food-related version. Sometimes leads to a DisneyAcidSequence. If it's a whole group of people experiencing it simultaneously, it's EverybodyMustGetStoned. See also ThroughTheEyesOfMadness and DrunkenMontage. Also often tied into DrugsAreBad.



[[folder:Anime & Manga]]
* ''Anime/CowboyBebop'' features the {{Trope Namer|s}} episode "Mushroom Samba": The crew confuses "magic mushrooms" with the regular sort, with the result that Spike ends up meeting a talking frog on an endless stairway, Faye steps into the water closet/loo and ends up in the ocean with fish going by, and Jet starts talking to his bonsai plants ("So that's it? I never realised the secret of the Universe was so simple! So by the way, who am I exactly?"), leaving Edward and Ein to track down the [[MonsterOfTheWeek crook of the week.]] This is after Ein has taken a small bite from one of the magic mushrooms and spent some time hopping around stiffly like a clockwork dog.
* ''Anime/SamuraiChamploo''
** There's an episode where a field of "grass" was set on fire, with... interesting results.
** Another episode is closer in spirit to its ''Cowboy Bebop'' predecessor, where the heroes run into [[spoiler: zombies]] and they and the viewer are partially left to question whether or not it was the result of some "wild mushrooms" they consumed at the episode's beginning.
* ''Manga/OnePiece''
** During the Alabasta arc, when the crew wanders through the desert, Luffy accidentally eats the wrong kind of [[AllDesertsHaveCacti cactus]], and apparently hallucinates about enemies. He also hallucinates about a tidal wave (in the middle of a desert?!) and tries to beat it up.
** Despite Luffy being the IdiotHero, he has a considerable amount of useful (and questionable) knowledge. Some of the questionable knowledge was shown when he first arrived in Amazon Lily, where he shows too much knowledge about hallucinogenic mushrooms (and start eating them in speedball fashion to cope with the fact that [[spoiler:he lost all of his crewmates and couldn't do anything about it]]).
* ''Manga/KimagureOrangeRoad'' has the cast in a field trip searching for rare blue mushrooms that would force anyone who ate them to tell the truth or act as their true self; naturally with the intent on using it on each other. To prevent this, one of the [=ESPers=] (Kurumi, male lead Kyosuke's sister) uses her powers to turn EVERY mushroom blue. As the characters contrive to feed each other fungus, various zany situations crop up due to the apparently behavioural-altering effects of common mushrooms.
* Sato's delusions from ''Anime/WelcomeToTheNHK'' are heavily implied to be this in the manga. In the anime they're implied to be schizophrenia. In the novel they're explicitly attributed to drug use.
* In the ''Anime/DragonBallZ'' movie ''Dead Zone'', Gohan eats an apple growing in Garlic Jr.'s garden. The minion guarding him goes nuts, telling Gohan that "Children can't eat those. They see things." Cue drug-trip montage.
** In the [[TheAbridgedSeries abridged version]], Vinegar (the minion, although his name is actually Nicky) warns Gohan that the apple is laced with LSD.
** In some dubs (e.g. Brazilian Dub), the Elite Mook warns him that the fruit is actually alcoholic, making it unsuitable for children. [[CantHoldHisLiquor That explains why he could eat them.]]
* A variant occurs in ''Manga/{{Eyeshield 21}}'', where after the game against the Nasa Aliens, Sena starts hallucinating out of exhaustion.
* In the manga ''Manga/YamadaTaroMonogatari'', Taro is given a bag of "flour" from a rich classmate, and uses it to cook pancakes for his family. Later, it is revealed that the huge bag of flour was actually narcotics made from magic mushrooms. However, due to being [[PerpetualPoverty extremely poor and starved most of the time]], Taro and his family were able to digest it with no problems or side effects.
* In ''Manga/AirGear'', Ikki and Shiraume end up consuming some funny Matsutake mushrooms, with some rather interesting effects. They end up 'fixing' one of Ikki's trecks and turn it into a formula racing car. In the living room.
* ''Manga/NininGaShinobuden'' has a large-scale one when the ninjas get some bad mushrooms while mushroom hunting. Then Onsokumaru eats some. Insanity ensues.
* In episode 4 of ''Anime/QueensBlade'', Reina tries eating a large, spotted mushroom for sustenance. Unfortunately, we don't get to see what she sees.
* During the infamous [[{{Filler}} island filler arc]] of ''Anime/NadiaTheSecretOfBlueWater'', Jean enacts this trope with actual mushrooms. During his hallucinations, [[MeatOVision he even visions Marie as a moving turkey dish]]. HilarityEnsues.
* The chocolates in episode 15 of ''Anime/BrigadoonMarinAndMelan'' produce... interesting... hallucinations in both the title characters. Leads to IntimateHealing.
* The ''Manga/HighschoolOfTheDead'' {{filler}} OVA episode, ''Drifters of the dead'' has the group unintentionally drug themselves by burning toxic hydrangea leaves, causing them all to hallucinate. And this being [[FanService High]] [[{{Ecchi}} School]] [[PantyShot of the Dead]] the hallucinations get a [[ParentalIncest little]] [[GirlOnGirlIsHot explicit.]]
* In ''Anime/BlackLion'' Shishimaru sets a field full of marijuana on fire causing Gennai Doma to hallucinate that there are multiple Shishimaru's and mutant scarecrows everywhere that he continuously cuts down with his sword.
* In ''Manga/UruseiYatsura'' the class eats Nabe and Cherry brings mushrooms which taste like Matsutake mushrooms...
* In the ''Anime/{{Bannertail}}'' episode "Akācho and the Flying Mushrooms," Akācho, wanting his (perceived) rival Banner out of the way so he can spend time with Sue, happens upon him eating acorns and says he has something ''much'' yummier, leading him to some red mushrooms which he tricks him into eating. The unfortunate young squirrel promptly experiences a lengthy tripout sequences wherein he mistakes his friends for predators and viciously attacks them, needing to be subdued.

[[folder:Comic Books]]
* This is actually one of the mutant powers of ''ComicBook/XMen'' member Pixie: secreting a hallucinogenic dust that makes people see bizarre things. It even made Wolverine run around the mansion trying to kill "freakin' unicorns!"
** One of the Marauders (not to be confused with the Harry Potter prankster group) is Vertigo. Her power screws around with spatial perception, causing an absolute loss of perspective as well as [[ExactlyWhatItSaysOnTheTin intense vertigo]].
* In ''ComicBook/AnimalMan'' Buddy and Dr. Highwater are led by a series of bizarre signs to the desert. On a mountain they find some peyote buttons and decide they are supposed to take them. When they do take them, a multiple issue trip involving talking animals, eyes appearing in the sky, and one of the characters 'killing themselves' ensues.
* Happened to Hal Jordan in one of his back-up ''Franchise/GreenLantern'' strips in TheSeventies with literal mushrooms, which he had picked wild and put into his chili.
* At some point in one of the ''ComicBook/CerebusTheAardvark'' story arcs, Cerebus is out and about with Prince Mick and Prince Keef, and Mick gives him... something which later causes Cerebus to observe, "... we're all PLANTS! Cerebus can feel it!" He spends the next few frames hallucinating that bits of his face are falling off, and scrambling after them to reattach them "before the sap freezes".
* The one and only full-color sequence in ''ComicBook/SinCity'' involves Wallace, the protagonist, getting drugged by an enemy. He then has to get in a [[MoreDakka gun fight]] and CarChase alongside his former commanding officer. The landscape looks like Creator/FrankMiller was channeling Creator/DrSeuss. During this time, the commanding officer morphed into ComicBook/{{Hellboy}}, {{Rambo}}, and even a beautiful woman.
-->'''Commanding Officer:''' Are you looking at my ass, son?\\
'''Wallace:''' Sorry, sir.
* In ''ComicBook/SupermanAndBatmanGenerations'', Dick Grayson as Batman is tricked into falling down a shaft lined with razor blades that are coated with hallucinogenics, so when he ends up fighting the Joker posing as Joker Junior, things get...really weird.
* In the ''ComicBook/LuckyLuke'' episode ''The Ballad of the Daltons'', an Indian witch doctor spikes the Daltons' drink with mushroom powder, giving them some pretty weird hallucinations.
* Jesse takes some peyote to commune with genesis late into ''ComicBook/{{Preacher}}''. The effects are... not pleasant.
* In the hilarious yet short lived 2001-2 comic ''ComicBook/PinkChickens'' there is a scene where the girls ingest large amounts of colourful sludge they find in the ship's fridge, after which they find out that it's actually liposuctioned alien fat. When they find out it's a hallucinogen too, hilarity and missing panels ensue.
* In ''ComicBook/DruidCity'', the lead character Hunter experiences a mild hallucinogenic episode after drinking a dangerous amount of alcohol directly after it is implied that he smoked marijuana. This was done deliberately so that he would not recall an unpleasant experience. [[http://druidcitycomic.com/comic/volume-1-page-135/ This little incident starts here]]
* Hourman apparently had one during a test run of an "improved" Miraclo pill formula in ''[[ComicBook/TheGoldenAge JSA: The Golden Age]]''. He flatly denies it in his monologues.
* In one issue of the French comic ''ComicBook/{{Rahan}}'', the eponymous caveman gets a nasty nightmare after eating some unknown mushrooms while starving during a crossing of the desert. At first he believes himself to be dead and to have reached the afterlife, populated with winged serpents and a huge two-headed dinosaur [[spoiler:that devours him]].
* At the climax of ''ComicBook/LeagueOfExtraordinaryGentlemen Century: 1969'', Mina takes tadukic acid in the hopes that the heightened awareness will help her find Haddo's cultists. Thus, she has a frightening drug trip that eventually leads to an out-of-body experience and a fight with Haddo's spirit. And the whole scene is set to a version of Music/TheRollingStones' "Sympathy for the Devil". [[spoiler:The scene ends with poor Mina going temporarily insane and getting committed to a mental hospital, while Haddo goes on to possess a certain professor named [[Literature/HarryPotter Tom Riddle]]...]]
* Batwoman gets multiple doses of fear toxin in the second arc of ''ComicBook/BatwomanRebirth'', leading to horrific hallucinations.
* In the ''[[ComicBook/SimpsonsComics Krusty the Clown]]'' special, Krusty has one when he drinks Krusty Burger's new "100% sugar, liquid-free" sodas.
-->'''Krusty:''' Yaaah! This is just like that [[Music/TheGratefulDead Grateful Dead]] concert all over again!

[[folder:Comic Strips]]
* ''ComicStrip/ZippyThePinhead'': Zippy, in Acapulco as an unwitting drug mule, is dragged off to a pool party full of jaded rich hedonists. He happily gobbles up all the recreational drugs scattered around like they were party snacks, and starts hallucinating wildly -- but [[{{Cloudcuckoolander}} he seems his usual self.]]
* A story arc in ''ComicStrip/BloomCounty'' had [[TVGenius Oliver]] extracting the hallucinogenic chemical from dandelions for testing, only for his father to drink the entire beaker. He ends up in the tool shed, yelling about Erik Estrada coming out of his belly button.
* One censored ''ComicStrip/{{Garfield}}'' comic which only appears as a rough sketch in the 25th anniversary book, features a half asleep Garfield as he watches a periscope emerge from his water dish, followed by a tentacle. Garfield then smiles and says, "Man, that was some gooooooood catnip!"

[[folder:Fan Works]]
* ''WebVideo/ImAMarvelAndImADC''
** The Green Goblin has a really powerful sedative injected into him to numb the pain while his superpowered healing system deals with [[spoiler:being run over by the Batmobile]]. He has some really funny hallucinations as a result.
** When Batman does the same to [[spoiler:Luthor]], this results in the both of them hallucinating. And singing.
* In ''FanFic/SixDaysTheAnimorphsWereIdiots'', the brightly colored clouds on the ''Literature/{{Animorphs}}'' book covers are explained as being a result of Marco's illicit drug use.
* ''VideoGame/TouhouMother''
** A parody of the Tanetane Island sequence from ''VideoGame/EarthBound'' has Marisa as the player character for that section because she's already used to the effects of magic mushrooms.
** Satori gets infested by the confusion-inducing mushrooms, causing her to behave impulsively and [[spoiler: [[EngagingConversation spontaneously proposition Mima]]]]. Afterward, she's too embarrassed to even speak with the party.
* In ''FanFic/BlackQueenRedKing'', ordinary candy hearts[[note]] the chalky Valentine's Day candy[[/note]] acts like a combination of weed and LSD for changelings. It also restores their sense of taste (much to their delight) and makes them involunarily secrete binding gel.
** Selene [[LampshadeHanging lampshades]] this with this line: [[FlatWhat “I don’t get it…”]]
* John Gage is injected by a druggie in the ''{{Series/Emergency}}'' fic "[[https://www.fanfiction.net/s/5056409/1/Blind-Faith Blind Faith]]'' and has one. Roy has to talk him out of swinging a fire extinguisher at the fires only he can see, thinking he's saving his crewmates.
* Nick of [[Series/{{Glee}} the Warblers]] in ''FanFic/HuntingTheUnicorn'' has a really bad trip after [[ComingOutStory coming out bisexual to his less-than-informed mother.]] He only remembers getting high to piss his mother off, going to Trent's place and getting drunk, then [[WhatDidIDoLastNight waking up in Jeff's room with glass in his boots]]. Flashbacks reveal that Nick and Trent kicked out Nick's mother's headlights. Thad later drove him to Jeff's place, where Nick thought he was turning into a bird, hallucinated that his cousin [[Film/{{Labyrinth}} Sarah's fiance was a barn owl,]] and [[ShipTease said "I love you" to Jeff.]]
* The Mist from FanFic/AngelOfTheBat is a potent hallucinogen that leaves those inhaling it in a state vulnerable to absolute horror. The Seraphim combines this with inkblots and violent imagery to try and break his captives. All that’s known about the drug for sure is it is very hard to detect and contains Scarecrow’s fear toxin.
* Dragons under the effects of Angel's Folly experience this in ''FanFic/TheLegendOfCynderSeries'', in addition to it [[PowerNullifier locking their powers.]] Cynder herself states she sees three Sparx' when [[spoiler: the sky pirates use it on her to keep her from escaping.]]
* In chapter 17 of ''Manga/{{Evangelion 303}} Mari got some LSD as a party favor when she went to a strip club. We see [[http://eva303.smackjeeves.com/comics/2168264/134/ part of]] [[http://eva303.smackjeeves.com/comics/2168265/135/ her trip]] at the end.
* Supermarioglitchy4sSuperMario64Bloopers:
** The episode "99.5% Crazy" revolves around Mario getting high off a Poison Mushroom [[spoiler:and staying that way for the whole blooper until he is cured buy a random 1up Mushroom that crawls into him.]]
** Mario goes high from several more Poison Mushrooms (and even from an overdose of pills) over the course of the series, with one instance ("Yoshrooms") having Yoshi join him for the ride.
* Luke Skywalker gets some Jedi-affecting shrooms that are presented as a gift when he's at an diplomatic dinner in the ''Franchise/StarWars'' fic ''[[https://www.fanfiction.net/s/4383163/1/It-s-a-Jedi-Thing-You-Wouldn-t-Understand It's A Jedi Thing, You Wouldn't Understand]]''. He winds up on the roof of the building, with a stick as his lightsaber, totally naked, retelling Han and Leia about Bespin.There are also some defaced garden statues involved. Han stuns him with his blaster to get him out of there. Luke later vanishes and Mara Jade (in the era before she was his wife) finds him singing bad karaoke in a bar. She keeps him from wandering off again but he's also rather amorous while he's intoxicated. Oddly though, they do end up having an enjoyable encounter later, and want to get together again. She does make him promise not to eat anymore mushrooms though.
* ''WebVideo/UltraFastPony''.
** In "To Kill a Firebird", Twilight and Fluttershy are trying to cure the bird Philomena, and Twilight forces a pill down the bird's throat. She thought it was medicine, but Fluttershy points out, "Oh no, that's my acid!" We don't get to see the bird's hallucinations, but she's high as a kite during the chase scene that immediately follows.
** That raises the question of why Fluttershy had acid in the first place... and "The Penny and Clyde Show" hints at the answer. When Discord's wave of chaos overtakes Ponyville, the other ponies become distraught, but Fluttershy just stands in the chocolate milk downpour, looks at the rabbits transforming into long-legged monstrosities, and remarks, "Oh, this is just a normal day for me."
* Steven manages to get high off some [[FantasticDrug Scorpion Powder]] in the first chapter of ''[[https://www.fanfiction.net/s/10225434/1/Starchild Starchild]]'' and wildly hallucinate about, among many things, a rabbit and the [[HasTwoMommies priestesses who helped raise his mother]] accusing him of ParentalIncest. It takes being whacked across the head to snap him out of it.
* In ''[[https://www.fanfiction.net/s/12522941/1/Bolt-from-the-Blue Bolt from the Blue]]'', Xanna tried to prevent her little master's abduction and got hit with an hallucinogen-laced tranquiliser. [[EpicFail She went Flame-Active as a result, messily killing the abductors and single-handedly rescuing Xanxus]]: when she tries to reminisce the facts, she can only remember flying, zombies, tentacle-flavoured purple and Xanxus with stripes and cat ears.
* In ''[[https://www.fanfiction.net/s/2900438/9/Unsung-Hero Unsung Hero]]'' Harry sees a lime green sky with pink clouds and a black moon after drinking the potion that reveals Animagus potential. He also hears flitterbugs talking.
* ''Fanfic/AllGuardsmenParty'': One of the ''Occurrence Border'''s docking bays is covered in caustic, psychically-active warp fungus. Hallucinations ensue when a shuttle of Space Marines accidentally docks in it.

[[folder:Films -- Animation]]
* One of the most classic Mushroom Samba scenes was in Disney's ''Disney/{{Dumbo}}'', where Dumbo drinks from a tub of water laced with champagne, and has a wild and disturbing musical fantasy sequence about "Pink Elephants on Parade". That must've been ''some'' champagne. In RealLife, zoopsia (the hallucination of animals, including PinkElephants) is a symptom of sustained alcohol abuse. Although elephants are ''terrible'' at holding their liquor. Most elephant-related fatalities are also alcohol-related. On the ''elephant's'' part.
* In ''WesternAnimation/BeavisAndButtHeadDoAmerica'', Beavis eats some peyote and goes on a hallucinogenic trip seeing himself and Butt-Head as rotting zombies and freaky demons everywhere playing the guitar, driving mini cars, etc., set to some trippy music performed by Music/RobZombie ("Ratfinks, Suicide Tanks and Cannibal Girls"). The scene was based on drawings of Rob Zombie's, the music was actually from Rob's now-defunct band White Zombie.
* Alex the Lion from ''WesternAnimation/{{Madagascar}}'' has a brief one after getting hit with a tranquillizer dart. Twice.
* ''ComicBook/LuckyLuke: WesternAnimation/LaBalladeDesDalton'' has [[http://www.youtube.com/watch?v=f63mfRtB93Q one]] after the Dalton Bros. drink mushroom-laced water.
* In ''Anime/TheDaggerOfKamui'', the progatanist Jiro and his newly found mother eat soup and then break into unexplained hallucinations. It was later revealed the soup was laced with poison by a minion of the film's baddie.
* Happens literally in the movie ''Animation/TheElmChantedForest'' when the hero is captured by talking mushrooms, who proceed to do a whole song-and-dance routine about how awesome it is to be a mushroom. At the end of the routine, they all suddenly grow fangs. It's loosely implied that this is because of something they gave him to turn him into a mushroom himself.
* Heavily implied in ''WesternAnimation/TheRoadToElDorado''. While in the middle of singing "It's Tough to be a God", Miguel and Tulio smoke some cigars, and the song turns into a full-blown DisneyAcidSequence.
** They were also drinking "Punch" throughout the song, and getting weird looks on their faces after each drink.
* In the ''ComicBook/{{Asterix}}'' movie "Asterix In America" after the medicine man drugs Asterix and Obelix with a PeacePipe so he can capture Getafix so he can make him the strength potion, after Obelix wakes up he hallucinates that Asterix is a giant fanged buffalo and he runs away when he approaches him.
* Happens in ''WesternAnimation/TheGoodDinosaur'' to Arlo and Spot when they eat old fruit that fermented in the sun. Both giggle like they're high, Arlo grows extra eyes, they scamper around together each with the other's head on his body.

[[folder:Films -- Live-Action]]
* The League of Shadows' blue flowers and Dr. Crane's fear gas/spray from ''Film/BatmanBegins'' seem to qualify. Decidedly not played for laughs, and in fact is used as a [[spoiler: panic-inducing]] plot point.
* Subverted in ''Film/EuroTrip'' where two of the movie's protagonists, predictably, decide to visit an Amsterdam bakery/coffee shop and trip out on hash brownies. Jenny gets the munchies while Scott simply freaks out (including the random, memorable confession "I saw a gay porno once. I didn't know until halfway in. The girls never came. The girls never came!"). When it gets really intense, the chef informs them that they do not serve hash brownies, meaning that the only thing they were high on was the placebo effect.
** It doesn't help that the bakery was owned and operated by Jamaicans. Who claim the brownies are "magical."
* ''Film/TenaciousDInThePickOfDestiny'' had JB eating mushrooms in a forest and going on an extended DreamSequence in which he was the son of the Sasquatch. He ends up nearly drowning and falling off a tree.
-->"Huh. This place is kinda.... '''''[[http://www.youtube.com/watch?v=e3L-_sOSB-o#t=00m21s JUICY]]'''''."
* ''Film/StarTrekIVTheVoyageHome'': Kirk tries explaining off Spock's alien behavior on 1986 Earth by saying that he suffered brain damage from too much "LDS" back in the sixties. The whale scientist doesn't buy it.
* In ''Film/BeverlyHillsNinja'', Haru, interrogating a source, uses a powder made from the "laughing mushroom" as a Truth Serum. However, he sneezes on it, he and love interest Sally Jones also inhale a dose, and the three sit around laughing their asses off at the most frightening and depressing truths.
* In ''Film/{{Salvador}},'' Doctor Rock (James Belushi) slips some LSD into an American TV journalist's cocktail. In the next scene she's talking to the camera, then suddenly sinks to the ground in a fit of laughter.
* In ''Film/LethalWeapon4'' Riggs, Murtaugh and Detective Butters are trying to get a Chinese mob boss to talk, so they sneak in on him while he's at the dentist and give him a snort of nitrous oxide. Unfortunately Butters leaves the inhaler on, so everyone in the room gets a little loopy, leading to the reveal that Butters has gotten Murtaugh's daughter pregnant.
* Most of the movie ''Film/AlteredStates'' consists of Mushroom Sambas... but they are hardly unintentionally induced, as the main character who undergoes them is researching the very drug behind the phenomenon.
* Played straight in ''Film/{{Labyrinth}}'', Sarah is given a "present" from Jareth - a peach which either causes her to hallucinate or actually transports her to a masquerade ball inside a crystal. There's also a possibility that the whole Labyrinth and such were hallucinated by Sarah, possibly because of a magical owl.
* Central plot device in the black comedy ''Film/DeathAtAFuneral'', whereby a pharmacology student creates an experimental designer drug and stores it in an empty Valium bottle. Throughout the movie Mushroom Sambas occur when the hallucinogenic pills are accidentally taken by three characters attending a funeral service. HilarityEnsues.
* ''Film/EmpireRecords'': Mark eats Eddie's "special brownies" and proceeds to hallucinate himself into GWAR's video for Saddam A Go-Go from the album This Toilet Earth, then getting eaten by the World Maggot (the same thing that ate Jerry Springer when GWAR was on his show). He seems to find all this very funny.
* ''Film/ReeferMadness'', with the pot brownie scene.
* In the 1996 film ''Film/WilliamShakespearesRomeoAndJuliet'', Romeo (Creator/LeonardoDiCaprio) is given an ecstasy pill right before going to the Capulet masked ball -- putting Mercutio's "Queen Mab" speech in a different light altogether. Some seriously trippy imagery from his perspective ensues.
* In 1996's ''[[Film/TheBradyBunch A Very Brady Sequel]]'', conman Trevor Thomas is served hallucinogenic mushrooms in a plate of spaghetti by clueless maid Alice; the subsequent sequence features animation (including dancing pandas and a helicopter-tailed wizard bird from the Creator/{{Filmation}} ''WesternAnimation/TheBradyKids'' cartoon) and the trippy Sixties anthem "Good Morning, Starshine" from ''Film/{{Hair}}''.
* ''Film/AcrossTheUniverse'' uses this. It's also taken to a greater level with all the visual imagery used and the fact that the music is by Music/TheBeatles...
* In ''Film/FreddysDeadTheFinalNightmare'', [[TheStoner Spencer]], played by Creator/BreckinMeyer, sees all kinds of trippy imagery coming out of the TV, set to Music/IronButterfly's "In-a-gadda-da-vida", and ends up in a video game.
* In ''Film/ASeriousMan'', the protagonists son Danny becomes a Bar Mizvah stoned.
* ''Film/TheBear:'' The eponymous bear cub finds some toadstools and, curious, eats some. He spends the next few minutes tripping out and whimpering, which is to be expected given what he sees.
* In ''Film/{{Go}}'' Manny takes a handful of ecstacy and while in a grocery store starts hearing 'Macarena' and hallucinates that he is dancing with the checkout lady and they are feeding each other bananas.
* In ''Film/{{Suck}}'', Joey mistakes two ecstasy tablets for aspirin before going out on stage. The result: an aptly titled musical number "This Is Your Brain On Drugs" with distorted colors and visions of three vampire band members leering at Joey.
* In ''Film/BadLieutenantPortOfCallNewOrleans'', in what is probably the film's best-known sequence, the protagonist snorts some heroin that he thought was cocaine, snorts some actual cocaine to try to balance it out, and ends up hallucinating about iguanas. Later on, after a climactic shootout, he orders that a dead man be shot again because "his soul is still dancing!" And the camera switches to his perspective to show that, yes, he is hallucinating the man's spirit break-dancing over his body.
* The Canadian film ''Film/MenWithBrooms'' had a lead character whose father was a regular 'shroom user. There were plenty of jokes about it, though no explicit hallucinatory scenes onscreen.
* When Jerry of ''Film/ConspiracyTheory'' is first captured by Dr. Jonas, his system is pumped full of [=LSD=] to make torturing him easier. His hallucinations and distorted perception of the world are notably played for drama rather than laughs.
* In ''Film/SnowWhiteAndTheHuntsman'', [[TheLostWoods The Dark Forest]] is feared as a hellish landscape with monsters, vermin, BodyHorror, etc. The Huntsman, one of the only people to enter the forest and return alive, explains that while the forest does have a few monsters in it and is treacherous, the real danger is the hallucinogenic spores.
* ''Film/AFieldInEngland'' features a twenty minute eye-bombing sanity-stripping example, with flash-cuts, mirror effects, swirly lenses, the works. WordOfGod states that a feature film normally has about six hundred cuts. This film has fifteen hundred cuts in ''the fifth reel alone''.
* In ''Film/UpstreamColor'', a woman is hypnotized by a thief who tells her that his face is made from the same substance as the sun, so she cannot look directly at him. From her perspective, we see her flinch away from bright light coming from the thief's direction.
* [[Film/PercyJacksonAndTheOlympians The Lightning Thief]]: The effect of the lotus blossoms, apparently.
* Used as a murder weapon in ''Film/YoungSherlockHolmes''.
* In ''Film/FathersDay2011'' Twink and Father Sullivan find Ahab's (toxic) berries and eat them, setting off a hallucination sequence. They even feed some to the passed out Ahab.
* Oscar's drug trip in ''Film/EnterTheVoid'' which we see from his POV. It's probably one of the more realistic trips shown on film.
* In ''Film/RoadTrip'' after Barry's grandpa eats some of E.L.'s pot brownies he hallucinates that his dog is talking to him:
-->'''Dog''': Hey old man I got the fucking munchies real bad!
* ''Film/TheHungerGames'': When Katniss is stung by the poisonous Tracker Jackers. This is admittedly LighterAndSofter than the book's presentation of the events.
* ''Film/TheWorldOfKanako'': The narrator goes through a heavy one after having been drugged by [[spoiler:Kanako]].

* In Book 4 of the ''Literature/LoneWolf'' series, ''The Chasm of Doom'', while in the Maaken Mines, breathing the spores of Calacene mushrooms can cause the hero to hallucinate of a fiendish monster (or a whole swarm of them). The "fight" that ensue cause real damage, however, since Lone Wolf keeps throwing himself against the sharp rocks of the tunnel.

* The late-1960s Hugo-nominated novel ''Literature/TheButterflyKid'' by Chester Anderson involves a plot by pacifist aliens to take over the world by overdosing humanity with a drug that causes ''solid, physical hallucinations that can be seen by people other than the one taking the drug.'' The idea is that human beings will find this so confusing that they will be rendered helpless. This does not work; the humans are all hippy stoners who enjoy the experience, generating creative hallucinations.
* In ''[[Literature/{{Wicked}} A Lion Among Men]]'', The Lion meets [[spoiler:some bears who act like stoners. On Honey.]]
* In ''Literature/BoredOfTheRings'', Frito eats some mushrooms and pills provided by [[WackyWaysideTribe whacked-out wayside hippie]] Tim Benzedrine and hallucinates until he passes out.
* In ''Literature/DoraWilkSeries'', after the main character is drugged so that she'd stop fighting, she has a darkly comical trippy sequence which would be funny if it wasn't for the fact that she's in the middle of [[spoiler:a rite whose purpose is to plant a demon in her soul.]]
* In ''Discworld/SmallGods'', Brutha meets a hermit, St. Ungulant, who lives in the desert, and occasionally eats mushrooms:
-->'''St. Ungulant:''' The desert becomes really interesting after the mushroom season.\\
'''Brutha:''' Full of giant purple singing slugs? Talking pillars of flame? Exploding giraffes? That sort of thing?\\
'''St. Ungulant:''' Good heavens, yes. I don't know why. I think they're attracted by the mushrooms.
* In Creator/RobertEHoward's ''Literature/TheHourOfTheDragon'', Literature/ConanTheBarbarian sees Xaltotun using the black lotus.
-->''It was the pollen of the black lotus, which creates deathlike sleep and monstrous dreams; and he knew that only the grisly wizards of the Black Ring, which is the nadir of evil, voluntarily seek the scarlet nightmares of the black lotus, to revive their necromantic powers.'
* ''Literature/{{Cryoburn}}'' opens with this. "Angels were falling all over the place... ''Ah, terrific. Auditory hallucinations, too.''"
* Soma is a regular cause of Mushroom Sambas in ''Literature/BraveNewWorld''.
* In George Alec Effinger's ''Literature/MaridAudran'' series, Bill the cab driver has had one of his lungs replaced with a container of a powerful hallucinogen, which continuously drips into his system. When he drives, he constantly swerves to avoid obstacles no one else can see, and holds conversations with the demons in the front seat of his cab.
* In "Steppenwolf" by Creator/HermannHesse the suicidal protagonist is rescued from his lonesome misery by some friendly strangers and their charming cigarettes. They take him to their 'Magic Theatre'(Not For Everyone/For Madmen Only/Price Of Admittance Your Mind) and they indulge in many drugs and Harry spends the last third of the novel reveling in hallucinatory adventures. At the end of the novel he snaps out of it briefly and is told that he has been in the Magic Theatre the whole time and making rather a fool of himself, but it's okay and they give him another hit.
* Literature/BloodyJack in ''Viva Jacquelina!'' a starving Jacky discovers some mushrooms growing on some manure, with the predictable results (including seeing a [[Music/JeffersonAirplane White Rabbit]] and talking to Brer Frog). When she comes down, she picks up '''more''' of the mushrooms to experiment with '''on other people'''. NotWhatItLooksLike Ensues
* ''The Purple Pileus'' by Creator/HGWells is a short story about a man whose crappy life is changed for the better after he trips out on some mushrooms he finds in a wood.
* ''Literature/TheHungerGames'': A (mostly) [[PlayedForDrama extremely unfunny]] version thanks to Tracker Jacker venom.
* Jules Verne's ''Around the Moon'' involves an incident where the group on the space capsule begins having bizarre arguments about the "moon people" (whose existence has only been speculated on with no evidence at all). It ends with each of them claiming to be the true leader of the moon. Then one of them realizes that someone left the Oxygen valve open and they've been getting high off pure O2 for hours.
* ''Literature/{{Bearheart}}'': Bigfoot takes drugs and falls in love with a statue at a park.
* Moonwatcher from ''Literature/WingsOfFire'': ''Winter Turning'' warns her friends to not eat any colorful frogs in the rainforest. The reason? She started having very weird dreams about newts and anteaters taking over the world.

[[folder:Live-Action TV]]
* On ''Series/{{Workaholics}}'' the main characters do drugs fairly often, but in the episode "Business Trip" the guys (with the exception of Ders) do acid, along with Alice, Karl, and a potential TelAmeriCorp client. Adam gets a bum tab, but Blake and Adam both freak out-Blake sees a worm alien monster trying to attack him, and Alice mistakes a chair for being Spanish and also hallucinates eating a hotel reception desk like it's jello.
* Most episodes of ''Series/That70sShow'' have either implied or obvious cannabis use. One Samba moment happens when Eric goes upstairs to make toast and runs into his father, Red; while they talk, the wall in the background is moving. Also, Red once accidentally eats a "special brownie" made by the kids. HilarityEnsues.
** Kitty voluntarily smokes a joint in the bathroom, and sees Red and Hyde's bodies morph.
* ''Series/{{House}}'':
** House uses LSD to beat off a self-induced migraine (which is another story). "I'm seeing sounds!"
** And Wilson, when House loads his coffee with ''sppppppeeeeeeed'' to see if Wilson was on anti-depressants.
** On another episode, House uses psychedelic mushrooms to treat a particularly obnoxious teenager's cluster headaches... he mellows out some. (Cue Iron Butterfly and swirling colors.)
** In season 8, Dr. Chi Park inadvertently ate some LSD-laced ice cream, seeing Chase as a rabbit, Adams as a sexy wolf, Taub as "either a tooth fairy or WesternAnimation/RainbowBrite", and [[ArsonMurderAndJaywalking House as...well...House.]]
* ''Series/TheGeorgeLopezShow'' features a drink involving a worm at the bottom of the glass. Drinking the worm induces an instant DreamSequence episode.
* ''Series/{{Life on Mars|2006}}'' has a sequence in the second season where Sam is accidentally given an overdose causing him to experience several hallucinations and a memorable DreamSequence where he and Gene are stop motion characters in children's show ''WesternAnimation/CamberwickGreen''. The best bit was probably Gene "beating up a nonce."
* In the ''Series/{{Coupling}}'' episode "Jane and the Truth Snake" Jane takes two paracetamol in a failed suicide bid, not having grasped the concept of an overdose. The pills actually aren't paracetamol but something she was given at a party, and HilarityEnsues as her [[SplitPersonality excessively straight-talking alter ego]] takes control in the form of a talking snake puppet.
* In an episode of ''Series/MyNameIsEarl'', Randy eats hippy face lotion and begins to see everything in claymation.
* While in the Deadly Swamp in ''Series/TheTenthKingdom'', Virginia and Tony consume magic mushrooms (and drink swamp water, which is apparently some form of alcohol). What makes this especially amusing is its literalism: while the mushrooms don't actually dance, they do sway in time to the music and sing their consuming victims to sleep (to Procal Harem's "Whiter Shade of Pale" no less!). Cue DreamSequence. But although the mushrooms seem hell-bent on their own suicidal destruction, this is subverted by the fact that it's all a ploy by the sentient man-eating swamp to shroud its victims in vines so they can be crushed, suffocated, and eventually consumed in turn.
* ''Series/SixFeetUnder''. David stows the E tablets he received from his club-hopping boyfriend in an aspirin bottle in the family kitchen. Ruth goes camping and packs the aspirin in her first aid kit. After getting a headache she does some serious wandering around in the woods. (See also IntoxicationEnsues for other repercussions.)
* In ''Series/PushingDaisies'', Aunt Lily takes an overdose of [[GRatedDrug homeopathic mood enhancers]] and starts hallucinating.
* In some of the early episodes of ''Series/TheGoodies'', Bill Oddie's hallucinations are crucial plot points. They are induced by
-->'''Graeme:''' LEMON SHERBERT?
::: Whenever the [[GRatedDrug sherbert]] comes up, it's often mentioned that his ''grandmother'' sends him it. It's also described as "Not dangerous, but it turns him on".
* In ''Series/FlightOfTheConchords'', Bret, after much fiddling around, accidentally takes a drug, leading to the lighthearted and whimsical "Prince of Parties" musical number.
* ''Series/TheXFiles''
** Scully starts tripping after getting a tattoo with ergot-laced ink. It's not played for humor at all, as the guy who convinced her to get the tattoo has heard his talking to him for weeks, and it's driven him to kill his downstairs neighbor.
** There's also "Field Trip," where Mulder and Scully investigate the skeletons of two hikers found in a field. It turns out that the field is covered in mushrooms that [[LotusEaterMachine trap those who step on them in vivid hallucinations]] while a BlobMonster under the field goes to work on digesting them.
** And Mulder goes on one in the 2016 miniseries episode "Babylon".
* ''Series/XenaWarriorPrincess'', "Altared States": Gabrielle eats some laced bread meant for Ikus. HilarityEnsues.
* Parodied in ''Series/MysteryScienceTheater3000'': Pearl Forrester decides to test LSD on the robots and they hook them up to screens so we can see what they see. Servo sees everyone as monsters, but cheerfully says they always look like that to him. The only thing that's different for Crow is that the Milky Way bar Mike was holding suddenly turns into a Snickers, which causes him to freak out. Crow is also surprised to learn that Mike isn't a clown.
* ''Series/StarTrekVoyager'' has a variation when the Doctor programs himself with the ability to daydream, which soon gets out of control and causes him to switch rapidly between various fantasies. The most amusing parts are the other characters using the holodeck to see his daydreams themselves and as they simply watch his reactions to the different scenarios he's entering and leaving.
* ''Series/OneThousandWaysToDie'' features more than a few ways to die by way of mind-altering drugs. One particular death features a dope who eats mushrooms, trips balls, tries to join a furry orgy in the wilderness, and gets EatenAlive by an [[BearsAreBadNews angry bear]]. Another has some folks doing acid, with one of them trying to jump into a pool, only to break her spine on account of the pool having no water in it.
* The ''Series/{{Dollhouse}}'' episode "Echoes" features the entire cast on one big tripout. The highlight of the whole thing is Topher desperately trying to stay lucid while explaining the situation to their dolls in the field on the phone, while in the background Adelle is jumping on a trampoline and shouts "Say hi for me!" just before he hangs up.
--> Adelle: ''I find lentils completely incomprehensible!"
* In one particular episode of the British series ''Series/MidsomerMurders'', straight-laced Chief Inspector Tom Barnaby tries some (special) brownies while interviewing a possible witness and subsequently comes over all giggly and walks along the top of an ornamental wall, all the while attracting confused looks from his Sergeant and the Coroner.
* The ''Series/{{Farscape}}'' episode "Taking The Stone" features Crichton eating one out of a cluster of four magic mushrooms in exchange for a confession from the episode's villain: the twist is that while three of the mushrooms produce a dizzying high, [[RussianRoulette one of them is lethal]]. Crichton manages to pick one of the safe mushrooms, thankfully, and spends the next minute doing a three stooges impersonation before passing out.
* One of the final episodes of ''Series/{{Lexx}},'' appropriately titled "Trip", half the crew consumed some mind-altering berry-like things that had been left as a gift, which led to some [[AHouseDivided interesting hallucinations]].
* ''Series/OneLifeToLive'' played it in a way rarely seen in fiction; as Cole was going through withdrawal, he hallucinated his family and friends berating him for what a horrible person he was and how he ruined their lives. Basically the Intervention From Hell.
* In one episode of the [[ExecutiveMeddling short-lived]] Comedy Central show ''Series/ThatsMyBush'', W accidentally takes two hits of Ecstasy, mistaking them for aspirin. HilarityEnsues.
* In ''Series/TheForgotten'''s "Train Jane", when Walter gets shot, the combination of panic and pain meds make him say wacky things.
-->'''Walter:''' Tell Candice I love her too, okay? But not in the [[StalkerWithACrush creepy way]]. And tell Maxine, her blonde hair's like a lighthouse in the darkness, a love lighthouse.\\
''(the doctor informs him that she's going to leave the bullet where it is for now)''\\
'''Walter:''' No, no!! You gotta take it out, it's evidence! If you're not gonna, I will! Someone get me a scalpel, stat! I saw this on Creator/AnimalPlanet!
* In the Granada Television TV adaptations of ''Series/SherlockHolmes'' (starring Jeremy Brett as Holmes), the stories nearly always stayed very faithful to the original works. In "The Adventure of the Devil's Foot," Holmes deduces that several people have been murdered with an exotic poison unknown to British science. In order to be sure that the suspicious substance recovered from the scene of the crime is indeed the mysterious poison, he deliberately exposes himself to what he believes to be a small dose... According to the original story, terrifying hallucinations ensue. In the TV version, the hallucinations shown are actually not particularly terrifying, but Holmes is presumably experiencing far worse ones.
* ''Series/{{Route 66}}'' has an episode where Tod gets a drugged drink at a party by mistake. As is typical of the show, it's not played at all for comedy.
* ''Series/HowIMetYourMother'' has a habit of replacing joints with sandwiches. [[JustifiedTrope Justified]] by the show's FramingDevice: Future Ted is supposed to be telling the story to his kids, and so the bit with the drugs is replaced with something more [[GRatedDrug G-rated]].
* In "Blind Man's Bluff," an episode from the second season of ''Series/TheSentinel'', Blair eats a slice of pizza which, unbeknownst to him, is laced with [[FantasticDrug "Golden"]]. A short time later he's wielding a gun in the police garage, and...well...
-->'''Blair:''' You don't see them? They're coming through, through the walls and the floor, man.\\
'''Jim:''' Who are?\\
'''Blair:''' The Golden fire people. You don't see them, man? They're made out of fire and they're burnt. You think they're ashes, but they're alive, man. And we gotta send them back!
* In ''Series/DueSouth'':
-->'''Fraser Sr.:''' I'm dead. I don't dream. So I don't know what this sensation is that I've got. Although it's very similar to when Walter Singlefoot laced my tea with knik-knik, then seemed to turn into a twelve-foot alligator before my very eyes.
* In a memorable episode of ''Series/BarneyMiller'', the detectives suffer interesting effects from munching a batch of brownies made by Wojo's current girlfriend.
-->'''Fish:''' The best I've felt in years and it's illegal!
* In ''Series/TheCloser'' episode "Smells Like Murder", Brenda's niece Charlie bakes a pan of special brownies, which Brenda later discovers. Brenda eats at least three, oblivious of their cannabis content. HilarityEnsues. When Fritz finds out, he is [[BerserkButton not amused]], and tells Charlie to [[GetOut start packing her bags]].
* In an episode of ''Series/YesDear'', Greg suffers from this in his desperation for nasal spray.
* People getting stoned on ''Series/{{Fringe}}'' is fairly common, but the episode "Lysergic Acid Diethylamide" [[note]]that's the scientific name for LSD, kids![[/note]] has some brilliant moments where Peter and ''Broyles'' start tripping. They're even funnier when compared to Walter and Bellivia, who take their LSD (don't worry, it's for MadScience) and don't react at all.
* ''Series/ThirtyRock''
** On the 100th episode, a gas leak causes Jack to hallucinate alternate versions of himself.
** Inverted in the LiveEpisode, where the different look and the LaughTrack are explained by Jack's ''lack'' of alcohol.
* Pierce descends into one complete with mocking animated skeletons in ''Series/{{Community}}'' episode "[[Recap/CommunityS1E07IntroductionToStatistics Introduction to Statistics]]".
** After breaking both legs in a trampoline accident, Pierce becomes addicted to pain pills, popping them way after he's healed, and talking with a six-inch tall AndyDick dressed like a pilot.
** While Pierce is painting Annie's apartment, the window ventilating the room shuts and the fumes get him hallucinating he's playing the piano flanked by two hula dancers,and he ends up making snow angels in the paint.
** Britta once shows up to the study room with frizzed hair full of various small items, ruined day-old makeup, and presumably a banana in her pants, and nonchalantly asks the group how long peyote lasts.
* ''Series/TwoAndAHalfMen'' - Charlie smokes pharmaceutical weed and sees hallucinations of various ex-girlfriends.
* Invoked verbally but averted in ''Series/{{CSI}}'' season 12, in response to DB Russell's personal mushroom garden in his office. They are *not* hallucinogenic, but he's gotten at least one joke about it already.
-->'''Russell''': Who killed Cock Robin? I, said the sparrow, with my bow and arrow. Who saw him die? I, said the fly, with my little eye...
-->'''Brass''': Those 'shrooms in your office aren't medicinal, are they?
** However, a hallucination-caused death happened at least once, it was the guy who got drunk on datura during a party in the desert and ended up dead and naked afterward.
* ''Franchise/{{Dragnet}}'' had its share, naturally. Mostly LSD-related, since it was the '60s.
* In ''Series/{{Dagvaktin}}'', hallucinogenic mushrooms accidentally get mixed up with real mushrooms in the hotel staff's vegetable soup, with character-appropriate results. [[ControlFreak Georg]] dons a colander and [[CrazySurvivalist builds a zealously-defended fortress out of food boxes, pot plants and cutlery]]; Gugga [[BrawnHilda grabs her shotgun]] and goes hunting for imaginary crows in the guests' bedrooms, and [[ShrinkingViolet Dan]][[GrewASpine íel]] strips naked and smothers himself in jam, insisting that 'wearing the jam [[NervousWreck takes away all my fears]]'.
* A non-comedic example in the season 3 episode of ''Series/HaltAndCatchFire'' "And She Was", it was implied that Donna has taken edible mushrooms while housesitting for Diane Gould and sitting on the grass she apologizes to Cameron for her dishonesty, Cameron accepts her apology, only to reveal that [[spoiler: it was a mushroom-induced fantasy]]
* ''Series/RedDwarf'' features an after-the-fact example in the past bits of "Stasis Leak", past Rimmer is convinced that his future self's holographic head sticking out of the table is a hallucination (same with the captain in a chicken suit).
* In ''Series/PersonOfInterest'' Finch, of all people, has one when a [=POI=] slips him some wine laced with Ecstacy.
* Done in ''Series/{{Victorious}}'' when discussing how Trina got into Hollywood Arts. Turns out Sikowitz had drunk some bad Sri Lanka coconut milk he had gotten from a cousin (he had forgotten it got delivered at his back door and didn't pick it up for three weeks). As all the other judges were busy with other matters, he was the only one around. So when Trina started singing he was hallucinating her wearing wearing costumes and everything in technicolor. Sikowitz believed it was part of her performance and passed her audition.
* In the ''Series/LawAndOrderSVU'' episode "Wet", Olivia is accidentally dosed by standing over a pot of boiling mushrooms in a suspect's lab. This results in her ranting like a paranoid wacko and passing out. It becomes a ChekhovsGun when Elliott fakes a samba of his own [[CourtroomAntic as a stalling tactic in court]].
* ''Series/MurdochMysteries'': One alcoholic drink served in a flask at the ''Alice in Wonderland'' costume party was drugged. Unfortunately, Detective Murdoch drinks it and IntoxicationEnsues. He becomes belligerent which is very much out of his character. Later he experiences unsettling visions of falling down a hole, being too big to enter a door or the grinning Cheshire cat watching him. It turned out it was just a prank, not originally pulled on the Detective, but the consequences were very serious. Detective Murdoch was suspected of murder and he had to sacrifice a lot, both professionally and personally, to make things right.
* ''Series/MadMen'', doing its [[TheSixties 1960s setting]] right, has now had ''two'' of these: In season 5, Roger took LSD with his wife and some friends, and had hallucinations that included hearing an orchestra when he opened a liquor bottle, seeing Don in the mirror while Roger's hair was two colors, and witnessing the 1919 World Series from his bathtub. Said hallucinations proved eye-opening in that they [[spoiler: made it clear his marriage to Jane was over]]. Season 6 had an even more blatant example with "The Crash", where the ''entire office'' took some kind of uppers. Though there were clear some hallucinations (like Don's flashbacks), much of the episode was left ambiguous as to what was really happening and what the characters were imagining. (The cripped Ken Cosgrove suddenly dancing out of nowhere?)
* Played for drama in ''Series/BurnNotice'' in the season 7 episode "Psychological Warfare", where Michael is given a hallucinogen to [[spoiler: encourage him to come clean about elements of his past. It works, but not well enough to blow his cover]]
* Being no stranger to comedic situations with extinct animals, the documentary Series/DinosaurRevolution had a ''Shunosaurus'' eating a few magic mushrooms. Then HilarityEnsues when aa pair of Sinraptors chase him. He ends up killing one and the other one runs away.
* In ''Series/DocMartin'' Series 5, after noticing bouts of hyperactive behaviour, Martin fires his new receptionist for taking drugs. He later finds out that the "energy pills" her grandfather had given her were actually 70-year-old metamphetamines from his WWII ration kit. Both assumed they were safe because [[GovernmentDrugEnforcement it had the Government stamp on]], after all... the Government wouldn't give out something that was ''[[InsaneTrollLogic bad]]'' for you.
* An episode of ''Series/BlackBox'' has Dr. Black recommend a terminal cancer patient take a substance that's basically 'shrooms. She has a friend of hers who is studying the substance's effects on cancer patients give her a sample. Planning to return the rest to the researcher, she puts the unmarked bag in her purse. Her fiance is making coffee, discovers the bag, assumes it's cinnamon or something, and puts it into both of the cups. Just as Black is asked to explain to a girl why pot is bad, she herself starts seeing things (more than usual, given her own psychological condition). Her fiance starts seeing live animals in her fridge.
* In the ''Series/BreakingBad'' episode "Mandala", Jesse has his first shoot of heroin, and is seen levitating off of his bed as he gets high. All while The Platters' "Enchanted" plays in the background. (Aaron Paul, the guy who portrays Jesse, was lifted up in a rig and filmed.)
* On ''Series/{{Shameless}}'' (US) Lip and Kev have great success selling marijuana in a college dorm but then Kev's supplier sells him synthetic marijuana which was laced with some unknown chemicals. Soon they have a room full of college students freaking out and having hallucinations. They manage to mostly contain it except for one guy who jumped out a window and broke his leg.
* On ''Series/{{Vikings}}'' this takes a very dark turn when, after a battle, Rollo ingests some mushrooms and starts seeing things. He hacks off the leg of a Saxon prisoner because from where he was sitting the leg looked 'strange'.
* Elliot of ''Series/MrRobot'' gets a long one in the third episode after taking some unidentified drug, featuring numerous scenes full of {{Foreshadowing}} and small metal keys.
* ''Series/LegendsOfTomorrow'': In the episode "Zari", Nate cooks up an hallucinogenic tea to aid Amaya on a VisionQuest to learn how to control her powers, and takes some himself to make sure it's safe. While for her it works perfectly, he just ends up high as kite -- to start with, his vision and motor skills are degraded, then he starts hearing things, and by the end of the trip he's spouting gibberish.
-->'''Nate''': Quiet, the marshmallows are talking!
* In an episode of ''Series/ThisIsUs'' Randall drinks a mushroom milkshake and hallucinates having a heart to heart with Jack.

* Hector Berlioz's Symphonie Fantasique has a scene in which the protagonist takes a large dose of opium to kill himself, he gets the dose wrong and proceeds to dream of watching his own execution after killing his love interest.
* Music/MitchBenn's "Tea Party" details the effects of various illicit substances administered (initially accidentally) to his unknowing aunty and uncle, with appropriate accompanying music for each new substance/verse.
* "[[http://www.youtube.com/watch?v=OR5v4yyPV6Y 5:15]]" from ''{{Quadrophenia}}'' documents the protagonist's drug-fueled train journey to Brighton.
* [[http://en.wikipedia.org/wiki/White_Rabbit_(song) The man on the chessboard get up and tell you where you go and you've just had some kind of mushroom and your mind is moving low...]]
** [[http://www.youtube.com/watch?v=WANNqr-vcx0 Go ask Alice, I think she'll know.]]
* This song chronicles the adventures of an [[http://www.youtube.com/watch?v=uQ3c8_ZTNrg LSD-addled Captain Kirk.]]
* "[[Music/TheBeatles Picture yourself on a boat by a river....]]" Although John Lennon credibly {{Jossed}} the theory that the title of the song (which, for tropers living under a rock, is "'''L'''ucy in the '''S'''ky With '''D'''iamonds") is a drug reference (apparently, he liked the phrase, inspired by a drawing by his son Julian), there's little doubt that the actual lyrics have are inspired by Lennon's psychedelic experiences. (Marmalade skies? Kaleidoscope eyes? Rocking-horse people eating marshmallow pies? Plasticine porters with looking-glass ties?)
* ''Blonde on Blonde'' by Music/BobDylan has ''Rainy day women''. Dylan allegedly said he could`t record the opening track with sober people, so he fired up a round of joints... Thus, everyone on the take is stoned out of their mind, making the recording a ''literal'' mushroom samba. The hysterical laughter in the background should be proof enough. ''Everybody must get stoned'' indeed.
* One of the possible explanations for the plot to Music/JobForACowboy's ''Sun Eater''. [[MaybeMagicMaybeMundane If the protagonist isn't receiving visions from a bonafide seance]], she's tripping balls on psychedelics (based on the nature of the visions and the album's flow itself, probably ayahuasca). "Worming Nightfall" is either where she gets trapped in a trip gone ''very'' wrong (if you believe it's drug-related) or in a dream world (if you believe it's supernatural). The band has intentionally left it ambiguous enough that both explanations are entirely plausible.

[[folder:Music Videos]]
* The music video for "Learn to Fly" by the Foo Fighters depicts the results of a drug stash being kept in the reservoir of the coffee machine on a commercial airplane that the band is riding in, and then that coffee machine being used to brew coffee for the entire place without noticing said stash. Everyone on the crew gets high, along with nearly all the passengers (except for Our Intrepid Heroes, who declined the coffee) start to hallucinate wildly. It is left to the band members to take the plane in for a safe landing.
* An innocent children's song about gathering mushrooms in the countryside... or is it? [[http://www.youtube.com/watch?v=Tre19TNUwIo Mangez-moi, mangez-moi, mangez-moi...]]
* In Music/PepeDeluxe's "Go Supersonic" music video, three guys each drink a "supersonic"-sized [[KlatchianCoffee Hot Sauce coffee]]. They then hallucinate a strange go-cart race.

[[folder:Video Games]]
* ''VideoGame/FarCry3'' has multiple interactive instances of this, induced by everything from hallucinogenic mushrooms, mystical potions, or just good old fashioned drugs.
** The moment that really stands out is the mission where Jason's sent to torch a bunch of marijuana plantations ''[[KillItWithFire with a flamethrower]]''. He starts getting a contact high from all the smoke and quite clearly having the time of his life; all the while, [[https://www.youtube.com/watch?v=PR_u9rvFKzE this music's]] blaring in the background.
** Continued in ''VideoGame/FarCry4'', which has a mission where you get high on the fumes inside an opium factory, an entire questline based around a pair of stoners testing their new formulas on you, and [[spoiler: a level where you are thrown into prison and drugged. Then you have to flee from hallucinatory demons.]]
* ''VideoGame/YoshisIsland'' has an infamous level called "Touch Fuzzy, Get Dizzy." Touching one of the fuzzy monsters that float around in the area will cause Yoshi to stumble around like a drunkard for a minute, distorting the music and the game screen.
** Called "[[FunWithAcronyms Lustiges Sporen Drama]]" in the German version.
** Stages 4-1 and 6-3 also have the Fuzzies, so be prepared for some InterfaceScrew in those stages, too.
** MFGG user gamester has made [[VideoGame/NormalSuperMarioBros a series of fan games]] based on the above mentioned "Touch Fuzzy, Get Dizzy," featuring [[http://www.youtube.com/watch?v=EzYq07N1YHU Mario]], [[http://www.youtube.com/watch?v=kR-Ij_DvUI4 Toad]], and [[http://www.youtube.com/watch?v=gfKUDqY3QA4 Luigi]], all feeling the effects of touching fuzzy (or, in Luigi's case, a fuzzy ''mushroom''.)
* Well, hello there, ''VideoGame/{{Earthbound}}''.
** A woman in Summers allows Ness to eat "[[GRatedDrug Magic Cake]]", which allows Ness to have a vision of Poo.
** Being hit by a walking mushroom's blast can make a mushroom grow from your head, which randomly changes the direction keys. Also causes confusion in battle until removed by a guy... who eats it.
** To say nothing of the coffee a Mr. Saturn offers. Though really, [[spoiler:speaking to your dad inside a Kaleidoscope]] is nowhere near as bizarre as... everything else in the entire game.
** What about Moonside? Or are we blaming that on [[spoiler:the Mani Mani statue]]?
* ''VideoGame/{{Mother 3}}'' continues the tradition:
** When the party is forced to eat some strange mushrooms found in the jungle -- in this case, it serves as a rather spiteful JourneyToTheCenterOfTheMind, as the hallucinogen preys on 'guilts and fears' (the party's [[EvilDetectingDog dog]] is the only one not taken in). The events were apparently supposed to be even more horrible, but the creator decided to tone it down.
-->'''Claus:''' Everyone's waiting for you. Everyone's waiting to throw rocks at you, spit on you, and make your life hell. Who's "everyone"...? Everyone you love.
** Thankfully for poor Lucas, his next high -- the return of the Saturns' coffee from the ''VideoGame/EarthBound'' -- is much less horrific.
* ''Videogame/NetHack'' has a hallucination status effect caused by (among other things) eating violet or yellow fungus, getting zapped by a black light, or drinking a [[IntoxicationEnsues potion of hallucination]]. It randomizes the appearance of every creature and item in the dungeon every time you take a step, and causes [[DevelopersForesight just about every in-game message]] to be rewritten in SurferDude speak.
* ''VideoGame/ZAngband'' grants monsters new names so you don't know what you're fighting -- the names change every turn along with the appearance of the monster, and run along the lines of Cosmic Horror, Incredible Lovemaking Robot, and so on.
* ''[=WazHack=]'' makes the screen go a glowing, wavy yellow and every living or dead being except yourself looks like a random geometric shape. Also, the random messages on the walls, which normally look like illegible scribbling even though your character can read them just fine, change into graffiti which says "IS IT TRUE OR FALSE? YOU'RE NOW TOO FOOLISH TO KNOW FOR SURE."
* ''Punch Quest'': Mutagenic Food causes rainbow colored wavy distorted images to appear.
* ''VideoGame/JazzJackrabbit 2'' has an afro-wearing caterpillar enemy, resting on a toadstool (inspired by ''Literature/AliceInWonderland'') who blows out ring-shaped puffs of smoke. When the player hits one of these smokerings, the entire stage's colours start to cycle around psychedelically for a few moments, and the player's movement becomes distorted for a moment (Left is Right, etcetera).
* In the game ''VisualNovel/{{Sprung}}'', in Brett's story, a hippie character gets him to eat some mushrooms for a 'ceremony'. It leads him to hallucinate loud flashing colours, come up with bizarre game overs, and visualise the hippie as a cow. Slowbeef's LetsPlay of the scene gives Brett some surreal NoFourthWall dialogue during the scene, even cribbing lines from other IntoxicationEnsues and MindScrew scenes as homage.
* The entirety of ''Lockjaw the Overdose'', a homebrew VideoGame/{{Tetris}} clone for UsefulNotes/GameBoyAdvance.
* Allure Seeds in ''VideoGame/PokemonMysteryDungeon: Red/Blue Rescue Team'' and X-Eye Seeds in the sequel games had this effect- if the character eats one then all Pokémon in the room become [[strike:strange green doll-like things]] [[http://bulbapedia.bulbagarden.net/wiki/Substitute Substitute dolls]] and all items, Wonder Tiles, and stairs turn into flowers until the effect wears off.
* The Fairy Ring in ''VideoGame/QuestForGloryI'' is comprised of Magic Mushrooms. Consuming them will cause the screen to change colors, with descriptions of the hallucinations ("Wow! Look at all the [[Creator/TheFiresignTheater nice paisley horses]]! Not to mention the beautiful neon sky."). The first time you eat the mushrooms, you're warned not to repeat it. If you do, the hallucinations resume, and "your mind permanently warped, you die a garishly polka-dotted death."
** A very similar thing happens when you smoke Salim the Apothecary's hookah in ''VideoGame/QuestForGloryIII''
* ''VideoGame/RiseOfTheTriad'' had a mushroom-shaped "power up" that put you in Shrooms Mode, causing most items (including the bad guys, fired missiles, and spring pads) to have a pulsating glow and the player's view to rapidly shift up and down. One of the game's secret levels was a big room filled with nothing but shrooms and spring pads, leading to some whacked out bouncy fun.
* ''VideoGame/{{Fallout 3}}'''s expansion, "Point Lookout", features an encounter with a psychoactive fruit which explodes in the player's face... followed by [[spoiler: having a lobotomy]] while the player character is [[InterfaceScrew hallucinating]].
** To say nothing about Vault 106 in the base game, whose experiment was to pump hallucinatory drugs into the air system and observe how the occupants reacted; said reaction was to go insane and murder everyone else inside the vault. If the Lone Wanderer goes inside for a length of time, [[InterfaceScrew he starts to experience the effects firsthand]], which manifest as unusual messages ''to himself'' on the computers and multiple illusions of his father and childhood friend.
** In the "Rite of Passage" quest from the ''VideoGame/FalloutNewVegas'' DLC ''Honest Hearts'', the Courier trips out on Datura tea, and has to fight a flaming Yao Guai ghost, which is [[YourMindMakesItReal just as deadly]] as its real brethren.
* The first ''VideoGame/MaxPayne'' game has two levels like this, once when Mona knocks him out with some unidentified substance in a drink, and later when the CorruptCorporateExecutive BigBad forcibly administers an overdose of V.
* In ''VideoGame/GrandTheftAutoIII'' and ''[[VideoGame/GrandTheftAutoViceCity Vice City]]'', when you take the adrenaline pills everything becomes very slow and everyone speaks in low, distorted voices. Also, the player becomes super strong and fast. One mission in ''Vice City'' starts after you encounter a side character's boomshine. You have to drive him to the hospital while very, very drunk. Something similar happens in ''VideoGame/GrandTheftAutoSanAndreas'', where you end up driving a van under the influence of weed after helping the van's owner torch an entire field of weed with a flamethrower. It happens yet again in ''VideoGame/GrandTheftAutoViceCityStories", when during one mission the protagonist is knocked unconscious with his face in a pile of cocaine, and has to complete the rest of the mission high after he wakes up.
** In ''VideoGame/GrandTheftAutoIV'', the player character can also get drunk, with realistic driving impairment effects.
** ''VideoGame/GrandTheftAutoV'' also features several different sequences fueled by psychedelic drugs, including a hallucination of free-falling over Los Santos half-naked and mowing down wave after wave of evil clowns. There are also hidden peyote cacti that when ingested, causes the character to trip as an animal for a certain period of time, accompanied with a narrative from the character.
* In ''VideoGame/DeusEx'', you can make the main character smoke cigarettes, drink alcohol and even do drugs. The cigarettes make him cough and lose health. The booze actually increases health a little, but makes vision worse. The drug (called "Zyme") has no effect on health, but screws up your vision for a long time.
* A staple in the ''VideoGame/SaintsRow'' series:
** In The ''VideoGame/SaintsRow2'' mission "Bad Trip", the Boss is doped to the gills for a meeting with the Sons of Samedi, and has to survive the mission under the influence, which here means "[[InterfaceScrew with blurry and tilted vision]]". It's also possible to drink alcohol (same result as the drug from the above mission) and smoke blunts (screen is covered in fog) whenever you want, though taking more than two at a time tends to hinder the player character in addition to the InterfaceScrew (too many blunts causes the Boss to randomly stop and cough up smoke, for example).
** In the ''VideoGame/SaintsRowTheThird'' mission "Pimps Up, Hos Down", the Boss is smuggled into Safeword (a BDSM club owned by the Morningstar gang) as a new sex worker, and ends up fighting their way through hordes of enemies alongside [[CoolOldGuy Zimos]], all while drugged-up and [[FullFrontalAssault buck-naked]].
-->'''The Boss (Female Voice 1):''' It's like living inside a ''rainbow''!
** ''VideoGame/SaintsRowIV'' continues the proud tradition in Shaundi's LoyaltyMission: after scoring a new alien drug, the Boss and Shaundi ([[spoiler:both of them]]) partake in it--and discover that it gave them actual superpowers. They proceed to complete the rest of the mission with their newfound powers while still tripping wildly (e.g. the Boss keeps seeing deadly enemies as colorful furries).
*** Several of the mission maps are hallucinatory prisons for the gang members The Boss is trying to rescue, in any event. Kinzie Kenzington may very well try to kill The Boss if he ever described what she was stuck in. I'll never try it, so that's a maybe.
* In the ''VideoGame/WorldOfWarcraft'' various alcoholic beverages (particularly during brewfest) can cause many different effects, from seeing pink elephants everywhere to seeing yourself swarmed by gnomes.
* In ''VideoGame/DonkeyKongCountryReturns'', DK and Diddy find a magic floating golden banana in the final level. After digging in, they find themselves in a mysterious land in the sky full of floating fruit platforms and koalas that are also half helicopter. One might argue that this wasn't a hallucination and they were actually transported to a land where giant cherries are actually proximity bombs. One might also be a little naive.
* ''VideoGame/GoldenSunDarkDawn'' includes an entire psychedelic dungeon, the "Phantasmal Bog", that is reached by having a collective bad trip on Dream Leaf harvested from a sickly tree. Once the tree is healthy, you can buy some Dream Leaf to use in the closed-up Border Town, causing a hallucination that the town is open, [[GuideDangIt allowing you to reach a summon tablet that is otherwise completely inaccessible]].
* ''VideoGame/KingdomComeDeliverance'' has Henry meet a group of women who bought hallucinogenic ointment from a witch in the hopes of seeing their loved ones again. Should Henry be spotted after they've applied it, they mistake him for Lucifer come to grant them their wish, only to smear the ointment on him as well and HilarityEnsues.
* ''VideoGame/TheLordOfTheRingsOnline'' has at least two examples of this trope:
** In the Water Works area, there are some giant toads who produce secretions that cause the player's character to have "hallucinations," wherein the screen colors change and there are other visual effects. And you don't even have to lick the toads. (In addition, the mouseover text for the debuff icon says something like "You can taste rectangles and smell the color magenta.")
** One of the quests in Evendim involves sneaking a mixture into some giants' cookpot, after which they start hallucinating that millions of spiders are coming out of the woods.
* ''VideoGame/{{Bug}} Too!'' has the final stages of the game, Cicada Night Fever. The ''entire level'' is one hell of an acid trip- the platforms are unnaturally colourful, the background contains Dali's clocks, you fight toads (from the first game) and floating Cheshire Cats, and the FinalBoss? Three of that smoking caterpillar from ''Literature/AliceInWonderland''... while deadly popcorn rains down from the sky.
* ''VideoGame/{{Aquaria}}'' features the Rainbow Mushroom...which doesn't do anything on its own, but mixed into Hot Soup it makes Rainbow Soup, whose effect is listed as "trippy". What this gets you is the same InterfaceScrew animation as a faceful of squid ink, but in rainbow colors. For about thirty seconds, anyway; after that the colors darken almost to black as Naija experiences the ''crash'' that almost never comes with this trope, letting out pained gasps at an alarming rate until the soup wears off after another thirty seconds or so.
* In ''VisualNovel/HatofulBoyfriend'', [[spoiler: Anghel Higure has a condition causing his body to produce hallucinogenic pheremones... to which [[RequiredSecondaryPowers he is himself not immune]]. His CloudCuckooLander behavior is because he is on a permanent acid trip.]] ...though it's also hinted that [[MaybeMagicMaybeMundane there is more to it]].
* In stage 3 of ''Videogame/LollipopChainsaw'', a local farm is taken over by a psychadelia-themed [[QuirkyMinibossSquad Dark Purveyor]]. Juliet will occasionally run across a giant mushroom that she needs to cut down to progress, and each time it triggers a trippy battle against a giant zombie chicken monster, followed by a minigame where you run over zombies with a combine while Dead or Alive's "You Spin Me 'Round" plays. Then after you beat the boss, you find out [[spoiler: the whole ''stage'' was [[AllJustADream just a hallucination]] caused by the boss's powers.]]
* While the Kid in ''VideoGame/{{Bastion}}'' doesn't really take anything, wandering around in Jawson Bog (which the Kid is warned about before hand that "That place'll eat your mind") eventually causes him to start having some rather disturbing hallucinations ([[MissionControlIsOffItsMeds including the narrator Rucks sounding more unhinged and hostile]],) hinting at the Kid suffering from SurvivorsGuilt.
* ''VideoGame/{{Blood}}'' had delirium shrooms, which showed up in the beta versions, but were never used in the final game(though some user-made level packs, such as Bloody Pulp Fiction use them). They caused the camera to wobble and sound to distort for a few seconds, rendering the game almost unplayable.
* ''VideoGame/{{Touhou}}'' canon itself has suggested that the magic mushrooms Marisa gathers from the Forest of Magic to power her spells are, in fact, "magic" mushrooms. Or possibly both.
* Many {{Roguelike}}s have hallucinogenic potions.
* ''VideoGame/UltimaUnderworld I-II'' and ''VideoGame/UltimaVIII'' have edible trippy mushrooms.
* Not even ''VideoGame/MarioAndLuigiDreamTeam'' was immune to this trope. [[spoiler: The "magic water spring" creates this which leads into a [[FissionMailed faked game over]]. It heals you as well for some reason...]]
* ''VideoGame/KnyttStories'' has ''Don't Eat the Mushroom'', played by LetsPlay/ProtonJon. [[https://www.youtube.com/watch?v=iGvZa3tiYwY Here's the link.]]
** Which also spun off countless imitators.
* Makoto's gag reel in ''VideoGame/BlazBlueChronophantasma'' essentially amounts to this when she receives candy from Kokonoe, which she shares with Taokaka and Valkenhayn. Allegedly, it's supposed to awaken the inner beast, but somewhere along the line [[spoiler:Taokaka pulls Makoto's tail off... and then ''the severed tail somehow comes to life''!]] Can you make shit like this up sober?
* In (the [[MindScrew already trippy]]) ''VideoGame/HotlineMiami2WrongNumber'', [[spoiler:the Son]] gets one of these after he has a bit too much of his own product. In it, he [[spoiler:slaughters both the Fans -- in the form of hallucinations of animals of the masks they wear -- and his own henchmen before walking off the edge of a building, seeing a rainbow bridge to Heaven]].
* In ''VideoGame/WeHappyFew'', the town of [[FalseUtopia Wellington Wells]] looks very different if you've been taking your [[GovernmentDrugEnforcement Joy.]] This is made especially clear in the game's prologue, where [[spoiler: the "piñata" the player character's co-workers are pummeling turns out to be a dead rat. And then they devour its putrid flesh with every sign of enjoyment.]]
* Mentioned in ''VideoGame/MassEffect2'' if a female Shepard romances Thane: if you talk with Mordin, he'll tell you that drell skin secretions have a hallucinogenic effect on humans and warn you not to, um, swallow.
* Subverted in ''VideoGame/MassEffect3'''s ''Citadel'' DLC. This is only what the [[TheGuardsMustBeCrazy casino guard]] thinks is the case when Javik claims [[WhileYouWereInDiapers to have met the guard's ancestors while they were living in caves and throwing rocks at wildlife]].
* ''VideoGame/BatmanArkhamSeries''
** In ''VideoGame/BatmanArkhamAsylum'': Batman wanders into three areas where Scarecrow is present and comes under effect of his fear toxin which starts changing the landscape before thrusting Batman in a nightmare world where he has to avoid the gaze of a giant Scarecrow and reach bat-signals to drive him off. The first two times Batman snaps out of it, he's in different areas meaning he somehow made his way to them through the hallucinations. The third showing it happens as a MindScrew to the players by having the game lock up and [[FissionMailed suddenly restarting to the intro sequence]].
** ''VideoGame/BatmanArkhamCity'': When Batman takes the League of Assassin's trials by drinking some of the Lazarus Pit, the liquid's effect has him suddenly in a desert like landscape where he has to follow Ra Al Ghul and fight several clones of him before he can pass. The battle against Ra also takes place in the same landscape for some reason. Also while not drug related, the side mission with The Mad Hatter has undertones of this via his mind control mask.
** ''VideoGame/BatmanArkhamOrigins'': Again the Mad Hatter side mission, which is longer this time has you traversing a rather whack out version of Wonderland while trying to track him due to some hypnotic device.
** ''VideoGame/BatmanArkhamKnight'', as Scarecrow is the main BigBad of the story, this pops up a few times such as in the intro sequence where he tests a new fear toxin on a diner causing everyone to hallucinate seeing zombies attacking them. [[spoiler: Batman gets spray with the toxin a few times, causing him to see Joker for the rest of the game as well as what he thinks is Barbara/Oracle's death in the middle of it as well as a few mind screw sequences such as battling dozens of Jokers where he's eventually forced to confront breaking his one rule: killing someone.]]
* The Scarecrow and his fear toxin play an intricate part of the ''VideoGame/InjusticeGodsAmongUs'' games:
** In the first game, in an alternate reality the Joker steals Scarecrow's fear toxin and causes Superman to mistake a pregnant Lois Lane for Doomsday. The ensuing fight obviously ends with the gruesome deaths of Lois and their baby. When Superman [[MyGodWhatHaveIDone realizes what he's done]], he GoesMadFromTheRevelation and becomes the BigBad of the series. Scarecrow himself only appears in a cameo though. In the Arkham stage, if the opponent is knocked into just the right spot, he'll run out, gas them, and the character briefly goes into Scarecrow's nightmare sequence from ''VideoGame/BatmanArkhamAsylum'' before getting knocked into another part of the stage.
** In ''VideoGame/Injustice2'', Scarecrow is a playable character and he makes this trope into his entire fighting style. He has no powers or weapons of his own, and before the match we see he's wearing a normal suit and burlap hood as he turns on his fear gas. His monstrous appearance, supernatural abilities, and even his chain and sickle are ''all hallucinations his opponent is experiencing''. Even in his prefight banter, he tries to get under his opponent's skin with personal details about them that he couldn't possibly know, like Supergirl's past on Krypton. That's when you realize Scarecrow doesn't ''actually'' know these things; [[FridgeHorror it's the fear gas messing with the opponent's mind]].
* In ''VideoGame/DragonAgeInquisition'', [[OldSoldier Blackwall]] mentions a previous assignment where he and his team lost all of their food to a flash flood. All that left them with were the berries that the newest member of the group had found. For the next two days, Blackwall thought he was surrounded by a ring of nugs that were singing sea shanties.
* In ''VideoGame/{{Lisa}}'', Joy is said to have hallucinatory effects, Allowing the user to feel nothing while driving the user to search out the thing they desire most. Brad often has flash backs and sees hallucinations throughout the game and is even hinted to have severe effects on his motives and psyche.
* In ''Videogame/PillarsOfEternity'', Zahua's personal quest has him and the rest of your party partaking of his stash so you can join him on a VisionQuest.
* In ''VideoGame/StardewValley'', after the local wizard gives the player character a dose of his brew to make them "one with the forest," dancing leaves and pine trees appear on the screen for a few seconds.
* ''VideoGame/RetroCityRampage'' has [[DrunkOnMilk a milk bar that gets the player drunk]] [[InterfaceScrew and makes the screen wavy]], and a merchant dealing in actual mushrooms with various effects.
* In ''VideoGame/{{Tyranny}}'', if the Fatebinder has a good enough rapport with [[EruditeStoner Lantry]], they can convince Lantry to let them try Lantry's inks -- all of which have at least some psychadelic effects. Red serves as a stimulant of some sort, sepia delivers a marijuana-like effect, and cerulean best fits the trope as it induces synesthesia and bizarre, [[PaintingTheMedium medium-painting]] visions.
* The intro to ''VideoGame/FredericResurrectionOfMusic'''s [[WelcomeToTheCaribbeanMon Caribbean]] stage has Rob blowing a cloud of smoke that makes the beach scenery more colorful. In the end, it's implied that everything that happened there was just Chopin tripping off second-hand marijuana smoke.

[[folder:Web Animation]]
* Vegeta undergoes this in ''WebAnimation/{{Ducktalez}} 7'' after eating some special brownies and drinking some booze beforehand.
* Lez of ''WebAnimation/TheBigLezShow'' goes through these frequently, but the longest one was the "flashback drug" sequence in Season Two.

** It's because of their [[IncrediblyLamePun coffin]].
* ''Webcomic/WhatBirdsKnow'' uses this metaphorically, if not literally (it's somewhat ambiguous in the story itself), when the female protagonists enter an AlternateUniverse where they experience bizarre hallucinations and... lay golden eggs.
* Tai from ''Webcomic/QuestionableContent'' apparently enjoys LSD from time to time. [[http://questionablecontent.net./view.php?comic=1279 At work.]]
* Ivy from ''Webcomic/{{Bobwhite}}'' snacks on some chips whose label warns, "High in cholesterol. May cause vivid fever-dreams." [[http://www.bobwhitecomics.com/?webcomic_post=20090106 She then hallucinates a visit from Bootsy Collins.]]
** Much later, getting lost and hungry on a fossil-digging trip causes [[http://www.bobwhitecomics.com/?webcomic_post=20100813 Marlene]] to hear the voice of Creator/AlfredHitchcock from her fern fossil. On the very next page, Ivy's spirit guide shows up, in the form of a fish wearing Bootsy Collins' glasses.

* ''Webcomic/{{Homestuck}}'' has Act 6: Act 5: Act 2, in which [[spoiler:Jane]] licks a giant magical lollipop, turns into a technicolor, creepily smiling version of herself. She then proceeds to turn all her friends into smiling technicolor versions [[spoiler:(However, Dirk isn't affected, despite him turning technicolor)]], form a sex cult, dance around a poorly rendered JPEG Christmas Tree to the sound of Jingle Bells as played on bicycle horns interspersed by random sound effects, forge legendary garishly colored artifacts, and then flood the world with garishly colored fancy porcelain Santa figurines. Even the ''narrator'' compares the magical lollipop to drugs.
-->Let us never speak of ACT 6 ACT 5 ACT 2 again.
* ''Webcomic/GirlGenius'' has a gas concoction that Master Payne's Circus of Adventure cooked up that they use to [[http://www.girlgeniusonline.com/comic.php?date=20070126 extricate Agatha and themselves]] from a brutal fight with Wulfenbach forces, simply by spreading it around and yelling "The [[BigGood Heterodyne Boys]] are here!"
** Not to mention the [[http://www.girlgeniusonline.com/comic.php?date=20070622#.VQxsDfnF8dI effects]] of drinking coffee brewed by a Spark-created machine.
* In ''Webcomic/ChampionsOfFaraus'', Skye and Karla accidentally [[spoiler:ingest a strange liquid that makes them see hypnolytic spirits as floating cat and lizard heads respectively]] while they are checking the House of Insanity.

* In the Third Night of ''Literature/TheTaleOfGavenMorren'', Gaven is dosed with [[FantasticDrug Elisdee Lily extract]]. Given that [[EverythingTryingToKillYou everything is out to get him already]], and you can see how not being able to tell what's a hallucination from reality might be a problem. The hallucinations manifest as frequent [[DaydreamSurprise daydream surprises]], the inability to recognize himself in mirrors, and even [[spoiler: hallucinating the presence of an [[ImaginaryFriend entire character]].]]
* Domo [[http://www.youtube.com/watch?v=gI4YkZxI9HE&feature=related Gets a Brainfreeze]]
* James Brown of ''Roleplay/SurvivalOfTheFittest'' says hi, he'll get back to you right after the Boos stop chasing him (a.k.a. epic acid trip).
* ''Roleplay/WeAreOurAvatars'': The Group ate some strange fish and had [[http://tvtropes.org/pmwiki/posts.php?discussion=i9k31ypluou9s5j9d2w7n23k&page=17384 strange reactions]] for a while.

[[folder:Western Animation]]
* ''WesternAnimation/BeavisAndButtHead'': Excessive caffeine or sugar was enough to turn Beavis into his psychotic alter ego "The Great Cornholio". Likewise, see TheMovie above.
* In the episode "Raisin The Stakes" on ''WesternAnimation/CloneHigh'', an anti-drug speaker tricks the entire high school into believing that raisins are a hallucinogen. Many drug montages take place of varying degrees of weirdness. (The entire episode is a rock opera ripped off from ''Music/TheWall'' and ''Theatre/JosephAndTheAmazingTechnicolorDreamcoat'' with traces of ''{{Theatre/Godspell}}'' and ''{{Theatre/Hair}}'' - very 60's-70's.)
* ''WesternAnimation/TheSimpsons'':
** [[Recap/TheSimpsonsS8E9ElViajeMisteriosoDeNuestroJomer "El Viaje Misterioso de Nuestro Homer (The Mysterious Voyage of Homer)"]]: After eating some of "the Merciless Peppers of Quetzlzacatenango" at a chili cookoff, Homer starts hallucinating wildly (which Marge mistakes for Homer breaking his promise about getting drunk) and goes on a journey to find his soulmate.
--->'''Homer:''' Man, this is crazy. I hope I didn't brain my damage.
*** One of the comics [[POVSequel set during the same episode, but instead following Chief Wiggum]] has this happen to him as well, causing him to, among other things, go on a rampage through town, envision a statue as a giant criminal, and see a spirit animal whom he then spends several hours [[ArsonMurderAndJaywalking asking what]] ''Film/TheMatrix'' [[ArsonMurderAndJaywalking was all about]].
--->'''Chief Wiggum''': "The merciless peppers of Quetzalzacatenango! Grown deep in the jungle primeval by the inmates of a Guatemalan insane asylum."
** In "Worst Episode Ever", Homer eats a box of ancient bicarbonate of soda (baking soda) ("I think it came with the house," comments Marge) on a dare from Bart, which causes him to have an "antacid trip" (and Bart to win $50).
** In "D'oh In the Wind", where Homer becomes a hippie, Flanders starts seeing [[Music/TheGratefulDead Grateful Dead]]-type bears, [[Music/TheWall Pink Floyd's Marching Hammers]] and [[Music/TheRollingStones Rolling Stones]]-type lips after drinking carrot juice laced with peyote. Barney sees a fanged monstrosity from the same drink, but is quickly saved by a beer and his friend Pinky, the pink elephant, Grampa and Jasper begin giggling like Beavis and Butt-Head (while sitting on a park bench in the same manner as Beavis and Butt-Head on their couch) and Willy sees a beautiful woman whom he starts kissing (which is actually a rake and the kissing is actually Groundskeeper Willy scraping his face with the tines of the rake).
** In "Homer Loves Flanders," Homer comments that Shelbyville threatened to spike Springfield's water supply after Springfield burned down their city hall, but they didn't have the guts. Cut to Marge drinking some water in the kitchen. Sitar music suddenly plays and Marge comments that the walls are melting again. A cooked turkey pops out of the oven and flies away.
** In "Selma's Choice", Bart dares Lisa to drink some of the "water" from a boat ride at Duff Gardens (which is so polluted, it doesn't really look like water anymore- either that or said water is actually beer). Once she does, she starts to hallucinate (starting with the Dutch dolls on the "Little Land of Duff" ride receding down a dark, endless hallway), becomes paranoid after seeing a monster grow from Selma's arm, tries to whack Bart and Aunt Selma with a boat oar, stumbles around the Duff Lite Parade commenting on how she can "see the music," and is found hours later after security saw her swimming naked in the Fermentarium, clad in only a towel and declaring herself, "[[Music/TheDoors The Lizard Queen.]]"
** In "Weekend at Burnsie's", when Homer starts smoking medicinal weed, he opens his bathroom's door with a 60's-style happy face, grabs a razor with a happy face, sees rainbows coming out of his beard, and then he gets on his car (with a happy face too!), under a pink sky and the smiling sun, his car takes off, and he drives away -- all with Donovan's "Wear Your Love Like Heaven" playing.
** There was also a subversion: in "Missionary Impossible", where Homer becomes a missionary, he starts licking hallucinogenic toads out of sheer boredom; however, the only thing we can see is his dilated pupils and his unusual reactions.
** In "I'm Goin' to Praiseland", where Ned opens a Christian theme park. He erects a statue of his late wife (the park was a lifelong dream of hers), and people who stand in front of it are hit with a vision of their idea of heaven, while onlookers see them writhing on the ground speaking in tongues. Everyone thinks it's something truly spiritual until Ned discovers a gas leak near the statue and that people were just "getting goofy off the gas fumes."
** In "Boy Scoutz 'N The Hood" where Bart finds a twenty-dollar bill. He and Milhouse buy an "all-syrup Squishee," which causes them to [[GRatedDrug behave drunk]] out of an extreme sugar rush and also causes the show to segue into one of the most memorable songs of the series. And towards the end of the song, it causes the boys to ''hallucinate''. [[spoiler: In reality, they end up joining the [[SuspiciouslySimilarSubstitute Junior Campers]].]]
** Also, in the episode "Homerpalooza" Otto hallucinates that his shoes are talking to him.
-->'''Otto:''' Don't worry, I won't hurt you. I only want you to have some fun.
** In "Bart Gets an Elephant", after sniffing some ammonia fumes Homer hallucinates that the cleaning mascots come to life and start dancing around causing him to laugh. Suddenly they spring out and attack him causing him to scream, Marge hears this and tells him to stop screaming so loud.
** In "Team Homer", Mr. Burns sees Homer as the Pillsbury Dough-boy while under the influence of ether, and since he's a big fan of his Homer uses this to get money for his bowling team from Mr. Burns. Burns then sees Hans Moleman as Lucky the Leprechaun, and tries to kill him and steal his brain to figure out the secret of his Lucky Charms.
** In "King of the Hill", when Homer is climbing the Murderhorn mountain, he starts feeling light-headed from the thinning atmosphere, then eventually says "Why should I climb when I can just take the escalator?" He then hallucinates that he's riding up the mountain on an escalator dressed in a suit and top hat, then leaping from peak to peak on the back of a blue mountain goat, then getting an elevator ride from the Abominable Snow-Monster from ''Rudolph the Red-Nose Reindeer''. Back in reality, he's actually tumbling down the mountain all cut up with a big smile on his face.
** In "Last Exit To Springfield" Lisa under the influence of laughing gas hallucinates that she is flying through the air and comes across a parody of Pepperland from ''WesternAnimation/YellowSubmarine'' and meets Music/TheBeatles in a purple submarine.
** In "Married to the Blob", Homer and Mr. Nakamura get drunk on potent rice wine and have a Creator/HayaoMiyazaki-inspired hallucination.
* ''WesternAnimation/{{Futurama}}'':
** "Hell Is Other Robots" has Bender "abusing electricity", which is apparently that universe's robot-drug. Not only is it very addictive, but the first time he takes a hit he has a wonderful but brief hallucinatory trip.
** Also, in the episode "The Farnsworth Parabox", the crew visits Universe 420, a universe where everyone is on drugs. We don't get to explicitly see anything there, but the main story of the episode is mind-trippy enough in its own right. As Fry says about the situation: "It's like that drug trip I saw in that movie while I was on that drug trip."
** Almost the entirety of the episode of ''The Sting'', combined with AllJustADream. [[spoiler: It's revealed in the end that the majority of the episode was Leela's dream while she was in a coma after getting a dose of venom on the bee's stinger that scratched her.]].
* ''WesternAnimation/CelebrityDeathmatch''; when an accident [[AdventuresInComaland sends Nick into a coma]], he has a bizarre morphine-fueled dream of Music/ElvisPresley and [[Music/TheGratefulDead Jerry Garcia]] fighting in the Deathmatch ring to the tune of the song "Kung Fu Fighting".
* In the ''WesternAnimation/RockosModernLife'' Halloween episode "Sugar Frosted Frights", Filburt eats Halloween candy for the first time and enters a sugar-rush-induced fantasy inspired by the "Night on Bald Mountain" segment from ''Disney/{{Fantasia}}''.
* ''WesternAnimation/HiHiPuffyAmiYumi'', "Rock and Roe": After eating too much sushi at a cheap seafood restaurant, Ami and Yumi start hallucinating.
* Jason from ''WesternAnimation/HomeMovies'' indulges in too much candy at Fenton's birthday party and begins behaving like a combative drunk. A concerned Melissa calls a cab for him.
* ''WesternAnimation/AvatarTheLastAirbender''
** The entirety of the episode "Nightmares and Daydreams". Note to people with no knowledge of why one should not stay up for three days: [[TruthInTelevision sleep deprivation makes your brain self-produce DMT]]. The dreams that cause the sleep deprivation are pretty weird as well (Aang with a BadassLongcoat and AnimeHair?). The crazy comes to a head when Aang imagines that Momo, a tiny TeamPet, is talking to him. This is followed by Appa, who is a giant, six-legged bison, talking along with the other characters as if it's perfectly normal, to the point where Aang ''doesn't notice.'' After Momo and Appa suddenly don Samurai garb and start fighting with swords, Aang declares his desire to dive under a cold waterfall.
** There's also Sokka and Momo's infamous trip from "The Desert", where they drink some [[AllDesertsHaveCacti cactus]] juice in order to quench their thirst while wandering around in the heat. The problem? The cactus was poisonous and had ''something'' in it (probably [[http://en.wikipedia.org/wiki/Mescaline mescaline]]), causing them to hallucinate and cause them to act just a ''little'' off-kilter.
* Toot, Wooldor and Xandir have one of these moments in ''WesternAnimation/DrawnTogether'' by licking Ling-Ling repeatedly. They try several things to make him "dis-ap-poin-ted", but eventually get bored and simply pass him back and forth. All three of them ''truly'' freak out when Ling-Ling's bodily secretions dry up.
** In the second half of "Lost in Parking Space" Toot drinks the saltwater from a fish tank and claims she sees a polar bear with a scorpion tail. [[BrickJoke It turns out true later on]].
* ''WesternAnimation/TeenTitans''
** The episode "Haunted" features a very unfunny example. Robin accidentally inhales an unnamed hallucinogen from an old mask of Slade's. Unlike most examples, however, this Mushroom Samba leads to what most fans consider the darkest episode of the series -- Robin hallucinates that Slade is everywhere and goes on a rampage trying to stop him, even going so far as physically hurting Starfire (his best friend and love interest) and threatening to "[[NeverSayDie take down]]" his team if they try restraining him. The drug manifests [[YourMindMakesItReal every blow on his body as though he really is battling someone]], and so before he realizes that bright light disperses the visions, he's nearly beaten to death... by himself. The Titans are convinced Robin has gone insane until Raven mind-links with him and gets a punch in the face by Slade herself.
** A less scary but still somewhat serious example: in "Crash", Cyborg gets his turn when Beast Boy accidentally gives him a computer virus. He then rampages crazily through town and [[ExtremeOmnivore eats everything in sight]], while having strange [[MeatOVision food-related hallucinations]].
--->'''Cyborg:''' ''(tearing apart an ATM)'' You can keep your sprinkles, I need raspberry filling!\\
''(he punches the machine, which causes a bunch of dollar bills to spill out into his mouth; he spits them out)''\\
'''Cyborg:''' No! Not macaroni!
*** At one point, the team approaches him cautiously, and he sees them as giant eggs!
---->'''Starfire:''' You remember who we are, yes?\\
'''Cyborg:''' You're the nasty egg people who stole all my waffles!
* ''WesternAnimation/SouthPark''
** The episode "Major Boobage" had Kenny getting high off cat urine and tripping out into a ''Heavy Metal''-style hallucination where there are breasts ''everywhere'' (even in the architecture!) Kyle's dad later takes a hit of cat pee, culminating in the two duking it out half-naked in a sandbox. At the end of the episode Kenny gets high on a bunch of flowers.
** All the boys (including Jimmy, Butters, and Token, but not Kenny) take hits of cough syrup in "Quest for Ratings," assuming that the wild hallucinations are bound to give them plenty of ideas to improve their school news show. They certainly have fun with the hallucinations, but the only "ideas" they emerge with are some squiggly lines and a circle drawn by Cartman and all the lyrics to the ''Series/HappyDays'' theme song written by Kyle.
* In the ''[[WesternAnimation/TheAngryBeavers Angry Beavers]]'' episode "Up All Night II" the eponymous beavers both suffer from lack of sleep. HilarityEnsues as the two beavers begin talking weirdly, acting weirdly and eventually even hallucinate the more and more their rational thinking starts to suffer due to lack of sleep. The episode's even more hilarious if you watch it while you are tired yourself.
* No surprise, but ''WesternAnimation/FamilyGuy'' has one too. A result of Peter and Lois smoking weed (again, as it turns out) to find inspiration to write a song for a contest. They end up licking Chris thinking he's a sundae in a magical world made of desserts and candies, lying naked on the couch together ([[{{Bowdlerise}} on the FOX and syndicated version, the two are in their underwear]]), and thinking they sang beautifully during the talent show (when, according to Chris, they were so baked, that they thought their off-key screaming was beautiful music).
** One occurs in "Seahorse Seashell Party" when Brian suffers nasty hallucinations after eating some bad psychedelic mushrooms.
* In the ''WesternAnimation/PhineasAndFerb'' episode "The Ballad of Badbeard", Candace starts hallucinating wildly thanks to some weird moss. She ends up following Perry on one of his missions, all along thinking she's just dreaming the whole thing.
-->"Why do my nostrils whisper to me..?"
* During Creator/DonHertzfeldt's "Intermission: In the Third Dimension!" sequence of ''TheAnimationShow'', one of his signature cloud characters dons 3D glasses, and hallucinates in ''3D!'' (A theoretical realm of space and time; where the laws of physics are meaningless!)
* Similar to the RealLife example below, in ''WesternAnimation/StarWarsCloneWars'', Anakin Skywalker gets a blast of steam in the face in a cave on Nelvaan. As a result, he starts seeing the cave paintings move. Considering how well the vision summarizes and foreshadows his own fall to the Dark Side, The Force probably assisted the lack of oxygen.\\\
This sequence parallels Luke's experience in the cave in ''Episode V'', where he receives a similar vision/warning about his own susceptability to the Dark Side. [[spoiler:Not counting his fall(s) in the Expanded Universe, Luke would seem to have payed more attention to this warning.]]
* This has happened a couple of times in ''WesternAnimation/KingOfTheHill''.
** In "Hillenium," Hank accidentally inhales some varnish while working on a grandfather clock ([[TooDumbToLive Hank should have known better than to close the garage door when working with chemicals that can cause hallucinations and brain damage when used frequently and in a closed space]]) and he hallucinates that he, his family members, and his hero Tom Landry are mechanical moles in a whack-a-mole game.
** In "To Kill a Ladybird" although we don't see his point of view Dale under the influence of wild mushrooms describes cartoon characters dancing around his head when he closes his eyes, that harmless animals are out to kill him, and that Hank is spewing bugs from his mouth.
** In "The Son Also Roses," the two stoners hallucinate that Hank has an enormous head, many mouths, and has a distorted voice.
** We even saw a pig's hallucination in the episode "Lost in Website/MySpace"
* Though not exactly a cause of drugs, one episode of ''WesternAnimation/MyLifeAsATeenageRobot'' had Jenny getting a dream chip installed so she can experience dreams. She starts to abuse it however and uses it during the daytime allowing her to see some pretty trippy stuff (all of her dreams are done in a different animation style). Things come to a head though when the chip gets damaged and she see everything in a Dr. Seuss style and goes on a rampage believing the people are Greek monsters.
* ''WesternAnimation/InspectorGadget'': "NSF Gadget" involves hallucinogenic "crazy gas" being placed into the oxygen supplies of astronauts, causing them to see visions of space monsters, and one of Gadget's hallucinations involves gigantic literal mushrooms.
* ''WesternAnimation/SpaceGhostCoastToCoast'': "Flipmode" involves Space Ghost interviewing Music/BustaRhymes (who laughs at nothing in particular for most of the episode) and breaking open natural gas pipes. This leads to mostly-unseen hallucinations and freak-outs by the entire cast.
-->'''Space Ghost:''' DIVE! DIVE! SUCK ON THE PIPES!
* ''WesternAnimation/{{Daria}}'': "The Teachings of Don Jake" has the Morgendorffer family (except Daria) losing their marbles on a camping trip by eating psychotropic berries (which Quinn calls "glitter berries"). They'd probably still be chasing the spirit animal if Helen hadn't brought her cell phone...
* In the ''WesternAnimation/AmericanDad'' episode "The Magnificent Steven" Stan buys Steve and his friends a small herd of cattle in an attempt to toughen them up, little does he know the cows are infected with Mad Cow Disease, during the course of events he make them slaughter the calf and only he eats the meat which causes him to hallucinate that owls are out to steal his meat (we don't see this), then he takes them to an alley where he hallucinates that he is in a bright more cartoony world and sings a Western song with a jack rabbit and prairie dog. We then cut to reality and he's dancing in his underwear with a beer pack and burger wrapper, he then orders them to cross a river which is actually a busy highway, and they end up having to save him from this. In real life he would've eventually died.
** In the episode "In Country...Club" after eating a rare bird Roger hallucinates that he's flying in a brightly colored CGI world with constantly changing shapes and floating in front of a singing gargoyle.
** In "100 A.D." after Roger puts some amphetamine droplets in his eyes and eats some expired cheese puffs he hallucinates that Klaus is Garfield in a bowl and Steve is a walrus in a Nazi uniform.
* ''WesternAnimation/TheVentureBrothers'' - Hank accidentally pokes himself with a [[PoisonedWeapons drug-tipped shoe spike]] of Molotov Cocktease's, and starts hallucinating, finally attacking his dad with a papier-mache sword.
* ''WesternAnimation/RegularShow'' has one of these in "Weekend at Benson's" as the result of Mordecai, Rigby, and Benson drinking [[BlazingInfernoHellfireSauce a super-spicy concoction]] known as "Mississippi Queen". The song of the same name even plays during the hallucinations.
* In the ''WesternAnimation/GravityFalls'' episode "[[Recap/GravityFallsS1E5TheInconveniencing The Inconveniencing]]", Mabel eats [[EleventyZillion bleventeen]] packets of a strange German confection called Smile Dip, which apparently got banned in America sometime shortly before the abandoned convenience store it was found in got, well, abandoned. It's never mentioned ''why'' the stuff is banned, but it's probably because it's capable of [[GRatedDrug inducing vivid hallucinations (as she soon discovers)]]. She spends much of the episode lying on the floor with her pupils dilated, hallucinating wildly and mostly unaware of what's going on around her.[[note]]She does manage to answer a direct question - "Mabel, how many of those did you eat?!" - but is otherwise unresponsive to anything outside of her own psychedelic world.[[/note]]
-->"The future... is in the past! ''Onwards, Aoshima!''"
* In the ''WesternAnimation/ScoobyDooMysteryIncorporated'' episode "Night Terrors", the gang stays at a mansion, and starts seeing terrifying hallucinations (also, Daphne [[KissingUnderTheInfluence sees Shaggy as Fred and kisses him]]). It turns out that the firewood the mansion was using was Terror Wood, which releases hallucinogenic chemicals into the air when burned.
* The Terras cause this to happen to the Burners on Halloween in ''{{WesternAnimation/Motorcity}}''. They release a special gas that forces them to see their biggest fears: comedic ones for Texas and Claire [[spoiler: giant candy and being married to Chuck]], respectively; serious ones for Mike and Julie [[spoiler: his past working for Kane and her father finding out she's a Burner]].
* Penny from ''WesternAnimation/LittlestPetShop2012'' has one of these when she eats too many sweets. Her friends, equally high on sugar, show other characteristic signs of being [[ICantBelieveItsNotHeroin on drugs]].
* ''WesternAnimation/BobsBurgers'' - while cooking Thanksgiving dinner with his family posing as his boss's family, Bob gets drunk on absinthe and has a glorious hallucinatory vision of a perfect holiday riffing off ''Anime/MyNeighborTotoro''. Another episode has him popping pain pills for carpal tunnel brought on by excessive videogame playing. He sees the bullies of his young mentor as characters in the 8-bit game and furiously chases after them.
* In the first episode of ''WesternAnimation/StarVsTheForcesOfEvil'', Star defeats [[BigBadWannabe Ludo]]'s minion Buff-Frog by stunning him with a "Jellybean Hallucination Mist".
-->'''Buff-Frog:''' I'm ''freaking out!''
** In the episode "Goblin Dogs", when Star, Marco and Pony Head finally eat the titular food, they're initially underwhelmed, thinking they're just ordinary hot dogs. Then they all experience a trippy rainbow-colored vision and agree that they they are the best hot dogs in the universe after all.
* ''WesternAnimation/VeggieTalesInTheHouse'': In "Bob and Larry: Gettin' Angry", Bob and Larry refuse to fall asleep...which winds up resulting in them seeing some rather strange things, like Jimmy Gourd walking across the ceiling and tiny versions of themselves dancing on each other....and that's not even getting into the DisneyAcidSequence that follows shortly afterward.

[[folder:Real Life]]
* TruthInTelevision, possibly: Some scholars of Greek literature believe that the Ancient Greek Oracles obtained their visions and heard the voices of the gods because they inhaled steam from natural geothermal vents for hours every day.
* ''Certain'' groups of people who are around even to this day owe their mythologies and legends to such experiences since they believed certain plants and substances had spiritual powers which could be tapped by eating or smoking them. As for who, well, [[RuleOfCautiousEditingJudgment it's probably better not to list them here]].
* The hallucinogenic properties of lysergic acid diethylamide (better known as LSD or acid) were discovered by accident by research chemist Albert Hoffman when he unknowingly ingested some that he came in contact with. Hoffman realized that he had made a significant discovery, and so three days later he deliberately took 250 micrograms of the drug, which he estimated would be a minuscule threshold dose. [[HilarityEnsues He was wrong]] -- the actual threshold is one tenth of that amount. Dr. Hoffman spent several hours terrified that he was possessed by a demon, that his next-door neighbour was a witch, and that that his furniture was threatening him, before relaxing into pleasant hallucinations of kaleidoscopic images in which every sound he heard became visible.
* Dock Ellis pitched a no-hitter on June 12, 1970 for the Pittsburgh Pirates while under the influence of LSD. He later spoke of the whole event, to which [[http://www.youtube.com/watch?v=_vUhSYLRw14 this video]] skillfully animates.
* Ergot, a fungus which grows on some types of grain during wet winters... and is apparently not destroyed when baked into bread along with the rye, can have hallucinogenic effects (along with gangrene and/or dying). Ergot contains ergotamine, a precursor to LSD. Some scholars believe that those who testified at the infamous [[WitchHunt Salem Witch Trials]] and similar events in Europe as having witnessed "witchcraft" and the Devil, had in fact been the result of a combination of religious fervor (i.e. they already believed demons and witches were everywhere)... and hallucinating due to eating ergot-infected rye bread. It should be noted that Albert Hoffman was in fact researching ergot when he discovered LSD.
** Ergotism is also suspected to be the cause of the [[http://en.wikipedia.org/wiki/Dancing_mania dancing plague]], a series of accidental medieval raves.
** This could also be the reason madness was believed to be infectious in medieval days due to an ergot infestation in a town's bread supply.
* Creator/BillHicks frequently talked about taking mushrooms in his stand-up routines, and referred to their effects as "squeegeeing his third eye".
* [[http://en.wikipedia.org/wiki/Psychopharmacology Psychopharmacology]] posits that hallucinogenic substance predates history, which is supported by its common prevalence among existing tribal societies today. These tribes also use them for religious/revelatory applications, and some of more radical psychopharmacologists (I'm looking at you, Terrance [=McKenna=], and God bless you,) "theorize" that our evolution into higher order thinkers was due to revelation brought on by hallucinatory and psychoactive substances.
* This can even happen without drugs, namely with high fever and sleep deprivation. And epilepsy. And comas. And semi-regular, nightly unconsciousness.
** Hypnagogic and hypnopompic hallucinations are where people have various sorts of hallucinations (most commonly seeing spiders) while falling asleep or waking up, respectively.
* In the 1970s, cops raiding an LSD factory in Wales failed to take into account that it had been making the stuff in large quantities for some time. The carpets, curtains, easy chairs etc. contained a significant quantity of spilled powder. They conducted a thorough search. Enough said...
* Both the [[https://www.youtube.com/watch?v=n-rWnQphPdQ British]] and [[https://www.youtube.com/watch?v=zLCzR34HfVQ American]] armies have experimented with LSD.
* The CIA experimented heavily with LSD during the Cold war, including the infamous MKULTRA mind control research. It got to the point where getting secretly dosed was a routine part of life as an agent.
