[[CowboyBebop http://tvtropes.org/pmwiki/pub/images/yourmindonmushrooms.jpg]]
[[caption-width:250:This is your mind on mushrooms.]]

Implied or accidental use of mind-altering substances by characters, but notably by the protagonists (villains, of course, can do anything). Usually very obvious to the attentive audience but may have to get around the censors under a different/invented name or by making the usage involuntary. 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, or steak sauce.

Typically great comedic fodder with a believable setup, but safer to do on cable. 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. See also LemonWackyHello, for accidentally-ingested substances that alter behavior without causing hallucinations, or 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.

'''No {{fanon}}, please!''' If it doesn't explicitly involve hallucinations caused by substances, don't reinterpret it as if [[EveryoneIsJesusInPurgatory Everyone Is Ringo On LSD]].

[[folder:Anime and Manga]]
*''CowboyBebop'' features the TropeNamer 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 (as pictured above), and Jet starts talking to his bonsai plants ("I know the secrets of the Universe! Now, who am I again?"), leaving Edward and Ein to track down the 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.
* Multiple occurrences in manga and TV series created by {{Rumiko Takahashi}}, such as ''[[RanmaOneHalf Ranma 1/2]]'' and ''UruseiYatsura''.
** In ''[[RanmaOneHalf Ranma 1/2]]'' the protagonists encounter a number of unusual mushrooms throughout the series, though the properties tend to be more magical in nature than hallucinogenic. Examples include the Age-Changing Mushroom (manga only), a mushroom that allows the use of post-hypnotic suggestion, and so on. There was also the "Incense of Spring Sleep", which caused Akane to have some strange dreams.
* ''SamuraiChamploo'' had an episode where a field of 'grass' was set on fire, with... interesting results.
** Not to mention another episode closer in spirit to its ''CowboyBebop'' 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.
* During the Alabasta arc in ''{{One Piece}}'', when the crew wanders through the desert, Luffy accidentally eats the wrong kind of 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 {{Idiot Hero}}, 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 could't do anything about it]]).
* ''KimagureOrangeRoad'' had 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 ''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 ''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 [[AbridgedSeries abridged version]], Vinegar (the minion) 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 (Vinegar) could eat them.]]
* A variant occurs in ''{{Eyeshield 21}}'', where after the game against the Nasa Aliens, Sena starts hallucinating out of exhaustion.
* In the 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 ''AirGear'', Ikki and Shiraume end up consuming some funny Matsutake mushrooms, with some rather interesting effects.
* ''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 ''QueensBlade'', Reina tries eating a large, spotted mushroom for sustenance. Unfortunately, [[MissedMomentOfAwesome we don't get to see what she sees]].
* During the infamous [[{{Filler}} island filler arc]] of NadiaTheSecretOfBlueWater, Jean enacts this trope with actual mushrooms. During his hallucinations, [[MeatOVision he even visions Marie as a moving turkey dish]]. HilarityEnsues.
[[/folder]]

[[folder:ComicBook]]
* This is actually one of the mutant powers of ''Comicbook/{{X-Men}}'' member Pixie: secreting a hallucinogenic dust that makes people see bizarre things. [[CrowningMomentOfFunny It even made Wolverine run away from "freakin' unicorns!"]]
* ''{{Nodwick}}'' had a strip where the evil undead anti-paladin Count Repugsive [[http://nodwick.humor.gamespy.com/gamespyarchive/index.php?date=2004-05-26 ended up tripping on too much cough syrup]]. [[FridgeLogic Don't ask us why the undead need to drink cold syrup]].
** It's because of their [[IncrediblyLamePun coffin]].
[[/folder]]

[[folder:Film]]
* One of the most classic MushroomSamba scenes was in Disney's ''{{Dumbo}}'', where Dumbo drinks from a tub of water laced with champagne, and has a [[NightmareFuel 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 pink elephants) is a symptom of sustained alcohol abuse. Perhaps it wasn't Dumbo's first time drinking from that water tub.
* The infamous "Boat scene" from ''[[CharlieAndTheChocolateFactory Willy Wonka and the Chocolate Factory]]'' (the version starring Gene Wilder) is certainly trippy enough to qualify as a MushroomSamba. Considering how much candy (including ''candy mushrooms'') the children had immediately beforehand, one has to wonder...
* Subverted in ''EuroTrip'' where two of the movie's protagonists, predictably, decide to visit a coffeeshop while in Amsterdam 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 are not hash brownies, meaning that the only thing they were high on was the placebo effect.
* Similarly to the RealLife example below, in ''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.
* ''TenaciousDAndThePickOfDestiny'' 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 several cliffs. It's utterly hilarious.
* In ''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. Man, where can I ''get'' somma that stuff?
* In ''{{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 ''LethalWeapon 4'' 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 ''AlteredStates'' consists of MushroomSambas... but they are hardly unintentionally induced, as the main character who undergoes them is researching the very drug behind the phenomenon.
* Played straight in ''{{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 ''{{Death at a Funeral}}'', whereby a pharmacology student creates an experimental designer drug and stores it in an empty Valium bottle. Throughout the movie [[MushroomSamba Mushroom Sambas]] occur when the hallucinogenic pills are accidentally taken by three characters attending a funeral service. HilarityEnsues.
* [=~Grandma's Boy~=] - no hallucinations, but the main character stores his marijuana in a jar in his room, which belonged to a now-deceased elderly lady who was friends with the titual grandma. His grandmother and friends run out of tea and decide to try the tea they found in the jar, leading to the [[WildTeenParty over the top party scene]]. Later bits of the story imply that the ladies were a lot more wild than they looked, but had been hiding their true nature from their boarder for fear of offending him.
* ''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.
* In ''{{Beavis and Butthead}} Do America'' Beavis eats some peyote and goes on a hallucinogenic trip seeing himself and Butthead as rotting zombies and freaky demons everywhere playing the guitar,driving mini cars,etc, set to some trippy music performed by Rob Zombie.
* Alex the Lion from ''{{Madagascar}}'' has a brief one after getting hit with a tranquillizer dart. Twice.
* ''ReeferMadness'', with the pot brownie scene.
* In the 1996 film adaptation of ''[[RomeoAndJuliet Romeo+Juliet]]'', Romeo (Leonardo [=DiCaprio=]) 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 [[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 {{Filmation}} ''Brady Kids'' cartoon) and the trippy Donovan anthem "Good Morning, Starshine."
[[/folder]]

[[folder:Literature]]
* Alice eats a mushroom and her size changes radically. Hmmmmm....
* The plot of the late-1960s Hugo-nominated novel ''TheButterflyKid'' by Chester Anderson revolves around 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.''
* In [[{{Wicked}} A Lion Among Men]], The Lion meets [[spoiler:some bears who act like stoners. On Honey.]]
* In ''BoredOfTheRings'', Frito eats some mushrooms and pills provided by [[WackyWaysideTribe whacked-out wayside hippie]] Tim Benzedrine and hallucinates until he passes out.
* 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.
[[/folder]]

[[folder:LiveActionTV]]
* Most episodes of ''{{That 70s Show}}'' have either implied or obvious cannabis use. One Samba moment happens when Foreman 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.
* ''{{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 ''[[MemeticMutation sppppppeeeeeeed]]'' for a lark.
** On another episode, House uses psychedelic mushrooms to treat a particularly obnoxious teenager's cluster headaches... he mellows out some. (Cue Jimi Hendrix and swirling colors.)
* In {{Firefly}}, Simon drugs Jayne to prevent him from taking over the ship.
-->''[Jayne is demanding that Wash take off for the delivery [[spoiler: without Mal and Zoe]].]''
-->'''Jayne:''' You know what the chain of command is? It's the chain I go get and beat you with 'til you understand who's in ruttin' command here! Now we're finishing this deal, and then maybe -- MAYBE we'll come back for those morons... got themselves caught... and you can't change that by getting all... ''bendy.''
-->'''Wash:''' All ''what?''
-->'''Jayne:''' You got the light... from the console to keep you... lifting you up... they shine like... ''[starts grabbing at the air]'' little ''angels''...
-->''[Jayne promptly falls flat onto the floor.]''
-->'''Wash:''' Did he just [[NonSequiturThud go crazy and fall asleep]]?
-->'''Simon:''' I ''told'' him to sit down.
* ''TheGeorgeLopezShow'' features a drink involving a worm at the bottom of the glass. Drinking the worm induces an instant DreamSequence episode.
* ''LifeOnMars'' 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 Camberwick Green.
** The best bit was probably Gene "beating up a nonce."
* In the ''{{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 ''{{My Name is Earl}}'', Randy eats hippy face lotion and begins to see everything in claymation.
* While in the Deadly Swamp in ''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.
* In an episode of ''[=~Trapper John, M.D.~=],'' Dr. Riverside is cultivating potted marijuana plants for his cancer patients. Straitlaced administrator Arnold Slocum, asking what those are, is told they're "herbs." He cuts some leaves onto his lunch and gets totally and amusingly stoned. (In fact, the cell walls of hemp are so tough that if you ate some it would pass through your system with no psychoactive effect; the active ingredient, tetrahydrocannabinol, can only be released through burning or very high-temperature baking (e.g., in brownies), which breaks down the cell walls.)
* ''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 LemonWackyHello for other repercussions.)
* In ''PushingDaisies'', Aunt Lily takes an overdose of [[GRatedDrug homeopathic mood enhancers]] and starts hallucinating.
* In some of the early episodes of ''TheGoodies'', Bill Oddie's hallucinations are crucial plot points. They are induced by...
--> '''Graeme:''' LEMON SHERBET?
* In ''{{Flight of the Conchords}}'', Bret, after much fiddling around, accidentally takes a drug, leading to the lighthearted and whimsical "Prince of Parties" musical number.
* In ''{{The X-Files}}'' Scully starts tripping after getting a tattoo with ergot-laced ink.
* ''{{Xena Warrior Princess}}'': In "Altared States" Gabrielle eats some laced bread meant for Ikus. [[HilarityEnsues Hilarity ensues]].
* Parodied in ''MysteryScienceTheater3000'': Pearl Forrester decides to test LSD on the robots ([[MST3KMantra yeah...]]) 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.
* ''{{Star Trek Voyager}}'' 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.
* The ''{{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.
* In one particular episode of the British 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 ''{{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 ''{{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]] [[HoYay hallucinations]].
* ''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 [[ThatsMyBush That's My Bush]], W accidentally takes two hits of Ecstasy, mistaking them for aspirin. HilarityEnsues.
[[/folder]]

[[folder:Music]]
* 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 epically 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.
* Mitch Benn'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.
[[/folder]]

[[folder:Musical]]
* ''{{Little Shop of Horrors}}'' has the evil dentist get himself off on nitrous oxide, OD-ing in the end. "Don't be fooled / if I should giggle / like a sappy, happy dope / it's just the gas..."[[/folder]]

[[folder:WebOriginal]]
* The Green Goblin from ''{{Im A Marvel And Im A DC}}'' 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 the Third Night of ''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, epic levels of HighOctaneNightmareFuel at a lurid carnival show, and even [[spoiler: hallucinating the presence of an [[ImaginaryFriend entire character]].]][[/folder]]

[[folder:VideoGames]]
* ''[[SuperMarioBros Yoshi's Island]]'' 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.
** And that stage isn't the unique that have those fuzzy monsters. The stages 4-1 and 6-3 also has the fuzzy creatures, so be prepared for some InterfaceScrew in those stages, too.
* Well hello there, ''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]]?
** ''{{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. It's still unrefined NightmareFuel, though.
-->'''Claus''': "Everyone's waiting, Lucas. Everyone's waiting to spit at you, throw rocks at you, and make your life Hell. Who's 'everyone?'... ''[[NightmareFuel everyone you love.]]''"
** Thankfully for poor Lucas, his next high--the return of the Saturns' coffee from the EarthBound--is much less horrific.
* ''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 [[LemonWackyHello potion of hallucination]]. It randomizes the appearance of every creature and item in the dungeon every time you take a step, and causes several in-game messages to be rewritten in SurferDude speak. ''Several'' messages? Actually, more like ''[[TheDevTeamThinksOfEverything just about every]]'' message.
* Angband has a similar effect. Monsters also receive new names so you don't know what your 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.
* ''JazzJackrabbit2'' has an afro-wearing caterpillar enemy, resting on a toadstool (obviously inspired by 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 ''{{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 LemonWackyHello and MindScrew scenes as homage.
* The entirety of ''[=~Lockjaw: The Overdose~=]'', a homebrew {{Tetris}} clone for GameBoyAdvance.
* Allure Seeds have this effect in ''Pokémon Mystery Dungeon: Red Rescue Team''- if the character eats one then all Pokémon in the room become strange green doll-like things and all items, Wonder Tiles and stairs turn into flowers until the effect wears off.
* This is the entire point of the Knytt Stories game titled "Don't Eat the Mushroom". It begins with the a giant screen of {{The Burger King}} and [[http://www.youtube.com/watch?v=iGvZa3tiYwY just gets crazier from there]].
* The Fairy Ring in ''QuestForGlory I'' is comprised of Magic Mushrooms. Consuming them will cause the screen to change colors, with descriptions of the hallucinations ("Wow! Look at all the 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."
* 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.
*{{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 chunk of the player character's brain removed]] while the player is hallucinating.

* In ''ScaryGoRound'', Shelley gets high on berry jam at the Tackleford Fair.
* The "Mushroom Samba" bit is taken literally in [[http://bukucomics.com/loserz/go/347 this]] ''{{Loserz}}'' strip. (Bit NSFW.)
* ''[[TakeOurWordForIt Supposedly]]'', [[ElGoonishShive Grace]] and her [[GRatedDrug catnip]].

*''BeavisAndButthead'': Excessive caffeine or sugar was enough to turn Beavis into his psychotic alter ego "Cornholio". Likewise, in TheMovie he eats some peyote in a desert and hallucinates. He comments that it's "like a music video." (The ensuing sequence was guest-directed by Rob Zombie)
* In the episode "Raisin The Stakes" on ''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 ''The Wall'' and ''The Amazing Technocolor Dreamcoat'' with traces of ''{{Godspell}}'' and ''{{Hair}}'' - very 60's-70's).)
*''TheSimpsons'', "El Viaje Misterioso de Nuestro Homer": After eating some of "the Merciless Peppers of Quetzlzacatenango" at a chili cookoff, Homer starts hallucinating wildly.
**In another episode, Homer eats a box of ancient bicarbonate of soda (baking soda) ("I think it came with the house," comments Marge), which causes him to have an "antacid trip".
**In the episode where Homer becomes a hippie, Flanders starts seeing Grateful Dead-type bears and 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, the pink elephant, and Willy sees a beautiful woman whom he starts kissing cut to real life he's kissing a rake and has scrapes all over his face.
**In yet another episode, Marge sees the walls of the kitchen melting after Shelbyville spikes Springfield's water with LSD.
**In "Selma's Choice", Bart dares Lisa to drink some of the water from a boat ride at Duff Gardens. Once she does, she starts to hallucinate, and ends up running out of the ride shouting (in homage to Jim Morrison) "I am the lizard queen!"
** And then, when Homer starts smoking weed, he opens his bathroom's door with a 50's-style happy face, grabs a razor with a happy face, sees rainbows coming out of his beard. (IfYouKnowWhatIMean...), 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.
** There was also a subversion: in the chapter 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.
**And then there's the episode 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."
**There's also an episode where Bart finds a twenty-dollar bill. He and Milhouse buy and "all-syrup Squishee," which causes them to hallucinate and appear drunk.
**Also, in the episode "Homerpalooza" Otto hallucinates that his shoes are talking to him.
--->Don't worry, I won't hurt you. I only want you to have some fun.
*In an episode of ''RockosModernLife'', Rocko and Filburt get "hangovers" from too much ice cream at Filburt's bachelor party and Heffer acts drunk. Another example is the Hallowe'en episode "Sugar Frosted Frights", where Filburt eats Hallowe'en candy for the first time and enters a sugar-rush-induced fantasy inspired by the "Night on Bald Mountain" segment from Disney's ''Fantasia''.
*In the ''FostersHomeForImaginaryFriends'' episode "Partying is Such Sweet Soiree", Bloo tricks Mac into eating sugar at a party, and the resulting sugar rush makes Mac act like he's on ecstasy.
*''HiHiPuffyAmiYumi'', "Rock and Roe": After eating too much bad sushi at a cheap seafood restaurant, Ami and Yumi start hallucinating.
* Jason from ''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.
* ''AvatarTheLastAirbender'', "The Desert": Sokka rashly gets water from the wrong kind of cactus and spends most of the episode in various stages of a drug trip. Unusually for this trope, the audience is not treated to a direct depiction of his hallucinations. At one point, he comments on seeing a "giant friendly mushroom" (this makes sense, though, as Aang created a roughly mushroom-shaped cloud of sand). Later in the same episode he eats a strange green substance on a cave wall, which lets him keep his sanity but once makes him think he hits a target when there's nothing there. His sister actually asks why he would [[WhatWereYouThinking do that after being on cactus juice all day]], to which he responds "I have a natural curiosity." Sokka's hallucinations may actually be a ShoutOut to the original Mushroom Samba, as the creators did say they were fans of Cowboy Bebop.
** The entirety of the episode "Nightmares and Daydreams". Note to people with no knowlege of why one should not stay up for three days: sleep deprivation makes your brain self-produce DMT. The dreams that cause said sleep deprevation are pretty weird as well (Aang as a BadassLongcoat with 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 after getting caught in a storm. "Who's this Aang person you keep talking about, your majesty?"
* In the ''SpongeBobSquarePants'' [[TheMovie movie]], [=SpongeBob=] binges on ice cream and acts as if he's drinking depressively.
* In the old ''LooneyTunes'' short “Birds Anonymous”, Sylvester’s desire to catch and eat Tweety Bird is treated as an addiction akin to drinking, and he joins the titular organization to kick his "bird habit". The cartoon is a fairly dark one, depicting him losing sleep, suffering terrible withdrawal, and even taking up ''chain-smoking'' in an effort to fight his bird cravings. Naturally, this cartoon never airs anymore due to MediaWatchdogs.
* Toot, Wooldor and Xandir have one of these moments in ''DrawnTogether'' by licking Ling-Ling repeatedly. They try several things to make him sad, 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 ''TeenTitans'' episode "Haunted," 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 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. Cyborg gets his turn when Beast Boy accidentally gives him a computer virus. He runs around crazily and eats everything in sight, while having strange food-related hallucinations.
* The ''SouthPark'' 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.
* In the ''AngryBeavers'' episode "Up All Night II" the titular 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 ''{{Family Guy}}'' had one too. A result of Peter and Lois taking drugs to find inspiration to write a song for a contest. They end up licking Chris thinking he's a sundae in a desert filled world, lying naked on the couch together, and at said contest, believing they performed beautifully when in truth they were just raving manics on the mics much to the horror of the audience.
* In the ''PhineasAndFerb'' episode "The Ballad of Badbeard", Candance 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.
* During Don Hertzfelt'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!)
*''LuckyLuke: The Ballad of the Daltons'' has [[http://www.youtube.com/watch?v=f63mfRtB93Q one]] after the Dalton Bros. get drunk.
*Happens literally in the movie "The Elm-Chanted Forest" 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 [[NightmareFuel grow fangs.]] It's loosely implied that this is because of something they gave him to turn him into a mushroom himself.

* 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.
* The hallucinogenic properties of lysergic acid diethylamide (better known as LSD or acid) were allegedly discovered when the chemist who made the stuff accidentally ingested some. He later took another dose and rode his bike home. Considering the LSD he had brewed was ten times stronger than the street quality today...
**He didn't ingest some, it was absorbed through his fingertips. [[HighOctaneNightmareFuel LSD can be absorbed through the skin]]. On top of that, a complete trip can be as little as 100 micrograms taken in- ONE TENTH of a MILLIGRAM.
* Ergot, a fungus which grows on some types of grain, can have LSD-like effects (along with gangrene and/or dying); considering that the active ingredient in ergot, ergotamine, is a chemical precursor of LSD, this is hardly surprising. It is believed that some of those who testified at the infamous Salem Witch Trials as having witnessed "witchcraft" and the Devil, had in fact been hallucinating due to eating ergot-infected rye bread.
* 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 it's 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.
