->'''Will''': Can somebody call me an ambulance? Because I'm in trouble. Time is moving really, really slowly, and everything is flat. I need you to call me an ambulance, or failing that, my mummy. I really want my mummy because, and I'm not being dramatic, but I think I might be dead. Is that clear? Mummy or ambulance. \\

-->-- ''Series/TheInbetweeners''

Marijuana is one of the less potent psychoactive drugs. It causes euphoria, thirst, hunger and occasionally paranoia, and it can also cause your thought processes to become one long string of FridgeLogic and/or [[FridgeBrilliance Fridge Brilliant]] moments (which may or may not be remembered once the effects wear off). It also takes a little while to get used to it--often, people doing it their first time don't feel any effects at all. Even very high doses won't cause hallucinations in 99% of the population.

You wouldn't know that from the movies, though.

DeanBitterman or the DotingParent is tricked or cajoled into smoking up, or more likely eating a pot brownie. Five minutes later, they're [[MushroomSamba riding a unicorn through a rainbow]], or arguing with the plants, or [[DisneyAcidSequence being chased by musical notes in time to the background music]]. Expect to hear Music/{{Steppenwolf}}'s "Magic Carpet Ride" or "White Rabbit" by Music/JeffersonAirplane. It's almost as if they've taken a powerful hallucinogen. Yes, in their universe, marijuana is LSD.

It is worth mentioning that large doses of marijuana can produce hallucinations in some people. The array of effects experienced from any dose vary considerably from person to person. Research into this effect may be partly responsible for the myth, along with journalists that ignored how large a dose the "psychonauts" used and what counts as a hallucination to experimental psychologists. Also, even those who regularly ''smoke'' cannabis may experience unexpectedly strong effects when ''vaporizing'' it, which is a more efficient method of administration. When ''eating'' it, it can take a long time to kick in, so a common mistake is to eat too much because it seems to have little effect - only to find oneself extremely inebriated for half a day when the full effects come on. Such an overdose can cause visual and auditory hallucinations, but those are not enjoyable at all and often combined with panic attacks, nausea and so forth. Hallucinations remain unlikely, but judgement and driving will be impaired. A person who has consumed enough marijuana to experience hallucinations is unlikely to be able to walk on two feet, let alone drive, so anyone who would have [[TamperingWithFoodAndDrink consumed it unwittingly]] would have called an ambulance at this point and not go on a wacky drug-fueled adventure.

It's a matter of debate whether second-hand marijuana smoke has any real effects (sometimes referred to as a "contact high"), beyond giving some people a splitting headache and nausea from the smell. Contact highs do occasionally turn up in fiction, usually in the context of someone being exposed to pot for a long period of time in an enclosed space like a vehicle.

May be a case of research failure, especially in older works. Seldom played straight in recent decades, but there are exceptions. Often overlaps with ScareEmStraight. {{Subtrope}} of GRatedDrug.

Another cause of this trope may be that the medium lacks the ability to portray intoxication from a first-person perspective accurately while also not making the intoxication seem much less powerful than it is. There are many drugs that have subtle and/or mild visual or auditory effects, if any at all, making it very difficult to portray the severity of a high dose accurately. Maybe it helps to think of the effects as metaphors.

Continuing on this trend, often when the effects of LSD are shown, they are powerfully overstated. Even on low doses, characters will experience detailed hallucinations and Datura-esque delusions, when in reality a single tab of LSD will usually only give someone visual distortions that are readily distinguished from reality.

This page also covers the use of exaggerated or inaccurate effects in other drugs. Examples which involve alcohol may also fall under PinkElephants.


* [[http://www.youtube.com/watch?v=jgJdVEoVbgg&feature=related This PSA]] If your dog is talking to you, chances are you have more than weed in your system.

[[folder:Anime and Manga]]
* Mugen in ''Anime/SamuraiChamploo'' torches a field of weed, which makes the fight scene with the warrior monks who grew the crop a bit... non-euclidean.
* Leigharch in the ''Manga/BlackLagoon'' anime hallucinates pretty wildly using marijuana, '''while driving'''. Averted in the manga, where his drug of choice is cocaine.
* Justified in one case of ''Manga/DetectiveConan'', where the marijuana that drove a manor full of society elites into a murderous frenzy is said to have been laced with something far more dangerous.

* In ''Fanfic/EmpathTheLuckiestSmurf'', [[FantasticDrug smurfnip]] is treated like marijuana with this trope. Notably in "Smurfnip Madness", Smurfette's hallucinations while under the influence include seeing Vexy and Hackus from ''Film/TheSmurfs2''. Also in the story, Handy created [[GogglesDoSomethingUnusual a special pair of glasses]] that simulate the visual effects of being under the influence of smurfnip. In "A Haunted Christmas", Nabby eats his stash of smurfnip during a village famine and starts having MeatOVision.
* Averted in [[http://www.jeffreysmorris.com/fanfic/efic/thebuzz.html this]] ''{{Series/Emergency}}'' fic. The station crew ate pot-laced brownies and had a realistic experience: euphoric period followed by a lethargic, calm period.

[[folder:Films -- Animated]]
* ''Disney/{{Dumbo}}'''s drunk sequence looks like this to many modern audiences, but it's actually just PinkElephants made literal.
* Plutonium nyborg, a FantasticDrug in the film ''WesternAnimation/HeavyMetal'', is a powder that is ingested like cocaine by the alien pilots of the segment "So Beautiful, So Dangerous" and produces hallucinogenic effects while leaving its users in a mellow state of euphoria, as sort of a combination of marijuana and LSD.

[[folder:Films -- Live-Action]]
* ''Film/ReeferMadness'', in which marijuana is like acid laced with speed. Not surprising given that it's an anti-marijuana propaganda piece. This is kept in TheMusical [[Film/ReeferMadnessTheMusical remake]], although now all exaggerations are played purely for laughs.
* ''Film/TransformersRevengeOfTheFallen'' features something more like "marijuana is PCP": Sam's mom eats one hash brownie and goes completely insane, even assaulting a full-grown man. Granted she's just shy of a {{Cloudcuckoolander}} as it is, but still...
** Michael J. Nelson of Podcast/RiffTrax riffed at this scene "This is apparently the type of pot that gets you drunk instead of high."
* Used and then Justified in ''Film/TrainingDay'', the marijuana was laced with PCP.
* Inverted in ''Film/TheMenWhoStareAtGoats'', in which a bunch of people drink water laced with high amounts of LSD, but for the most part just act like mellow, happy stoners.
* ''Film/ClassOfNukeEmHigh'' has an excuse for this--the marijuana was grown [[ILoveNuclearPower next to the nuclear power plant]].
* ''Film/HalfBaked'' uses this trope, but at least it only seems to apply to the ''really good shit'' Thurgood gets from the government lab. Semi-justified in that it is so good that other people can see your hallucinations too.
* ''Film/EuroTrip'' had the group visit Amsterdam. During a visit to the bakery, they started hallucinating wildly only to be snapped back when told by the waiter that [[FakeHigh they were eating just regular brownies]].
* Uniquely reversed by ''Film/{{Skidoo}}'': The film's climax involves spiking the food supply of a prison with LSD as part of an escape plan. However, [[CriticalResearchFailure only one member of the cast or crew had actually had any experience with the drug]] ([[spoiler:Creator/GrouchoMarx's final film credit]]), and they weren't anywhere near that sequence. So, lacking any sort of direction, everyone settled for either acting ''drunk'', or [[LargeHam trying to compensate with volume]]. How they got Timothy Leary to endorse that is a mystery.
* ''Film/{{Friday}}'' sort of touches on it; when Craig gets high, aside from the mellow feeling, fits of giggling and occasional paranoia, he also sees double and/or gets blurry trails, sounds tend to echo, and he hallucinates at least twice, once with Big Worm's head appearing to talk to him in a cupboard. He's also smoking the stuff used by a guy whose NAME is Smokey, and for good reason. In fact the only time Smokey even looks ''affected'' is in a flashback, when he smokes a joint laced with angel dust.
* In the [[TheSeventies early seventies]] educational film ''Focus on LSD'', marijuana and hashish are listed as psychedelic drugs along with LSD, mescaline, peyote, STP and psilocybin.
* In ''Film/HowHigh'', smoking marijuana and smoking a dead president causes a spirit to appear and communicate.
* ''Film/TheRoom'': In a scene recalling ''Film/ReeferMadness'', normally cool-headed Mark becomes uncharacteristically violent and belligerent after taking a couple hits from a joint, holding a supporting character against the edge of a rooftop. Fits in with the recurring theme of the film that DrugsAreBad.
* ''Film/TheBreakfastClub'': When the gang tries Bender's weed, Andy becomes very enthusiastic and starts dancing around the library, even backflipping, among other gymnastic moves. He also slams a door, breaking the glass.
* ''Film/TouchOfEvil'' treats marijuana as just about the most dangerous drug out there. Heroin gets a brief mention, sure, but it's the "reefer sticks" planted on Suzy that are seen as the real damning evidence, and when she's told some people are high on pot, she takes immediately takes it as a sign that they're dangerous. And even the criminals who deal marijuana are careful about not using it themselves, saying no one in their family "gets hooked" on the stuff.

* According to ''Doctor Wood, Modern Wizard of the Laboratory'', Robert Wood (patron saint of EducationThroughPyrotechnics) in his youth once tested whether it's true that cannabis is hallucinogenic ''when ingested''--for the sake of experiment and because, well, there weren't any reports of fatal poisoning or something. It was. Most memorable scenes of this [[strike:trip report]] "experiment summary" involved turning into a fox whose eyes were inside the mouth and being scared shitless by a two-faced doll.
** As if he'd never heard of a pot brownie.
* Author Creator/JTEdson was violently opposed to marijuana and any time it is portrayed in his novels, it is shown in a negative light. However, he also appears to have no idea of what its effects actually are, and it is portrayed as everything from a date rape drug to driving people into a beserk frenzy like PCP.
* In ''Literature/FearAndLoathingInLasVegas'' the speaker at the drug conference seems to have no idea of what pot actually does. Much lampshaded by Duke and Dr. Gonzo, who are quite familiar with several different drugs.
* In ''Literature/FriedGreenTomatoesAtTheWhistleStopCafe'', Evelyn smokes a joint with her daughter, only to have all the potholders on the kitchen counter get up and start walking toward her.
* In the [[BasedOnAGreatBigLie fictional]] MiseryLit book ''Literature/GoAskAlice'' the protagonist tries marijuana, amongst other drugs such as heroin and ecstasy, but they all seem to give the same effect.

* There's an episode of ''Series/{{Frasier}}'' which parodies this--Martin eats a hash brownie, not realising what it is, realises he's stoned after a short period of time, and then starts to ''think'' he's hallucinating when he sees a video in which Eddie, the dog, appears to be speaking. The video is actually a mock-up commercial, introduced in another subplot, that overdubs Eddie with his mouth moving with Frasier's voice.
** Martin spends most of his "trip" thinking he feels strange because of the cough syrup he took that morning. There ''is'' a brand of cough syrup well known for mild LSD-like effects.
** In the same episode, Niles ate a normal brownie which he thought was a hash-brownie and started showing the symptoms of being stoned at once until he was made aware of the mistake, at which point he instantly "sobered-up".
--->'''Niles:''' I'm especially looking forward to something called the "munchies" stage. It's where one enjoys bizarre food combinations... I'm thinking of pairing this Chilean sea bass with an aggressive Zinfandel!
* Parodied on ''Series/{{Monk}}'' in the episode "Mr. Monk Visits a Farm". Monk (mistakenly) thinks he's inhaled some weed smoke when he ends up catching Jimmy Belmont in the act of destroying marijuana crops that Harvey Disher had threatened to turn him in for, and starts freaking out. HilarityEnsues. "I'm getting the munchies! Oh God! Reefer Madness!"
* ''Series/That70sShow'': the scenes where Eric has to talk to his parents while high, and the wallpaper behind them is moving/swirling and his parents swap heads.
** There was one episode where Leo accidentally fed his marijuana stash to his dog, who ends up having such a hallucination.
* Parodied in an episode of ''Series/{{Taxi}}'', which features a flashback to Reverend Jim's college days, where he is a straight-arrow book-grinding nerd named James Caldwell. He gets talked into eating a marijuana-laced brownie: one bite, and his expression instantly (and hilariously) dissolves into Reverend Jim's crazed bug-eyed stare.
* In ''Series/BreakingBad'', Jesse sees two men in white shirts who want to talk to him about Jesus as hulking, leather-clad thugs with machetes and hand grenades after smoking methamphetamine. Possibly justified, since he could have gone a long period without sleep or began to suffer from stimulant psychosis, both meth-related issues that cause hallucinations.
** Definitively justified. Meth can cause Hallucinations even without lack of sleep. Alternately, it could have just been a visual representation of meth-induced paranoia.
* In ''Series/PartyDown'', Roman eats multiple pot brownies without realizing they're laced. He curls up in the bathroom and calls for an ambulance, because he is either dead or soon will be. After the paramedics show up, the hippie fellow who baked the brownies leads Roman on a journey to meet his spirit animal and Roman writes a screenplay (on the toilet paper). The paramedics take him to the hospital, not because he's overdosing on pot, but because they've never seen anyone that high before and want to show the nurses.
** And strangely enough, about 75% justified. Party Down is pretty good about portraying drugs realistically and it's specifically mentioned that Roman ingested about a tenth of an ounce of high-grade marijuana. For someone not accustomed to the effects of marijuana, eating that much certainly could make one feel as if they were going out of their mind. The other 25% is RuleOfFunny.
* In ''Series/{{Community}}'', the pill Star-Burns gives Pierce during a Halloween party has Pierce acting like he's rolling on ecstasy...then he starts hallucinating Annie making cracks about his age as talking calaveras fly around. That he was also mixing this with his regular prescriptions (of which he had lost track and was taking random doses) probably contributed.
* In the ''Series/{{Room 222}}'' season 1 episode "Goodbye, Mr. Hip," a teacher gets in trouble because of a student prank, a fake joint filled with pencil shavings placed on his desk. The teacher tries to prove his innocence to the principal by saying "Look at my eyes! Are my pupils dilated?" Marijuana makes eyes red and puffy, but only LSD dilates the pupils.
* In the ''Series/TwoAndAHalfMen'' episode "Gumby with a Pokey", Charlie finds himself with insomnia and is given prescription marijuana by his pharmacist to help him sleep. After smoking it, Charlie has disturbing visions of women he slept with in the past and sees Music/ZZTop in his living room.
* In the opening of an episode of {{House}}, the soon-to-be patient of the week is a priest who hears a knock at his door. When he answers he sees a floating Jesus complete with stigmata and crown of thorns. Later in the episode Dr. Hatley chalks this up to ''the single highball of liquor'' the man consumed just before. [[SarcasmMode Differential diagnosis?]]

* During his 2002 "Live on Broadway" special, Creator/RobinWilliams came down on the IOC for treating marijuana usage in athletes on the same level as steroids:
-->'''Robin''': [A snowboarder tested positive for marijuana], which is kind of redundant, number one. Number two, they said marijuana was a performance-enhancing drug. ''(imitates "Incorrect" buzzer)'' Marijuana enhances many things--colors, tastes, sensations--but you are certainly not fucking empowered. If you're stoned, you're lucky if you can find your own goddamn feet! The only way it's a performance-enhancing drug is if there's a big fucking Hershey bar at the end of the run.
* Played straight by Creator/WoodyAllen, who describes marijuana as a "major hallucinogen," and recounts an incident where he took a puff of the wrong cigarette and ended up trying to hijack an elevator to Cuba.
* One Creator/LouisCK story involved him overdosing on weed (as he forgot that modern weed is vastly more potent than the stuff he smoked in his teenage years), and proceeded to have a very unpleasant experience.

[[folder: Video Games]]
* Inverted in ''SamAndMax Season 2: Moai Better Blues'', where basalt is said to make [[EenieMeenieMinyMoai Moai]] 'turn on, tune in and drop out' (a phrase associated with LSD). If you feed one of the Moai basalt, he claims that he's hallucinating, but otherwise just acts giggly and stoned. He also exhales stone dust in a way that looks like smoke, Sam jokingly calls him 'Cheech', and Max teases him for being a lightweight by not holding it in for more than a few seconds. [[FantasticDrug Obviously this is]] [[RuleOfFunny justifiable, though]].
* In ''VideoGame/GrandTheftAutoV'', there is a "Freaks" mission that Michael can take on where he comes across a man trying to get marijuana legalized in San Andreas, and keeps insisting Michael, a man who typically only smokes cigars, to try his "home grown" joint. Upon reluctantly doing so, Michael suddenly goes into a bad trip where he is ''shooting aliens with a minigun'' (which is fully playable). After the trip ends Michael tells the marijuana guy to screw off and says he'll never try a joint ever again. The same thing happens to Trevor as well, only with clowns instead of aliens. Franklin however is unaffected since he's already a habitual pot smoker. Somewhat averted, however, in that it is clearly indicated (by the more experienced Franklin) that the pot in question has been doctored in some fashion (but one must play the optional mission in order to find this out), as Michael can smoke pot in his house a get a more mundane high.

* [[http://gunshowcomic.com/420 This]] ''WesternAnimation/{{Shrek}}''-based ''Webcomic/{{Gunshow}}'' comic, which is coincidentally (?) the 420th comic in the series.
* ''Webcomic/SweetBroAndHellaJeff'': [[http://www.mspaintadventures.com/sweetbroandhellajeff/?cid=037.jpg SUDDENLY WEED DREAMS]]. [-poofl-] Considering [[StylisticSuck what comic we're talking about]], it was probably intentionally invoked.
* Squigley's marijuana use in ''Webcomic/{{Sinfest}}'' looks like this at first, but it eventually becomes clear that he's not hallucinating that he can fly while stoned. (He describes himself as a "shaman," and his powers are effective even in Hell, though they stop working in the [[AntiMagic reality zone]].)

[[folder:Web Original]]
* WebVideo/FilthyFrank once smoked a contaminated joint (in reality, a carrot and a piece of cabbage wrapped in notebook paper) and hallucinated that a flying banana killed Pink Guy.

[[folder:Western Animation]]
* Averted and parodied in ''WesternAnimation/KingOfTheHill'', when Hank accidentally smokes a joint ("Pretty funny lookin' cigarette.") but feels no genuine ill biological effects. Hank is so [[WrongGenreSavvy familiar with this trope]] that he naturally assumes that the drug has transformed him into a crazed maniac and caused him to black out (in actuality, his "blackout" was just a much-needed nap).
** Played with in another episode that featured two typical stoner kids who run a headshop. They have a more realistic reaction to weed where they're just very relaxed and giggle a lot. However their [=POV=] gets a little "trippy" after listening to Hank talk while high.
* ''WesternAnimation/TheSimpsons'':
** Homer is given medical marijuana for his eye injuries. He sees a number of Beatles-esque hallucinations, mostly everything smiling at him (including his razor) and any flowing liquid (like his blood from cutting himself shaving) as rainbows.
** In another episode, Lisa becomes completely stoned and begins hallucinating smiley faces everywhere, culminating in her almost making out with an electric fan. Her drug of choice? Anti-depressants.
* In ''WesternAnimation/CloneHigh'', ''raisins'' are like LSD... [[ShapedLikeItself ON ACID]]!
* In ''WesternAnimation/FamilyGuy'', the episode where Peter and Lois had a band. They used Marijuana as the group's muse and it doesn't take much to get them completely baked, rolling on the floor and moaning nonsense (while thinking that they were singing a great song while unicorns danced in the background). They had similar trips throughout out the episode, another of which involved them licking Chris under the hallucination that he was a sundae. [[AvertedTrope Averted]] in the series' pot-centric episode, "420."
* ''WesternAnimation/SouthPark'':
** There's an episode where Mr. Mackey -- of "DrugsAreBad, m'kay?" fame -- is finally convinced to try mari-jou-wanna. Mackey frolicked around and a few of the objects in the alley he was in changed into bright neon colors. Later, when convinced into taking LSD, his head becomes a free-floating children's balloon. Interestingly, Mr. Garrison averts this when he's seen smoking marijuana. He's simply seen mellowed out and giggling at a cartoon.
** Another episode features men in town deliberately getting testicular cancer (by putting their balls in the microwave) in order to be able to legally buy marijuana from the local seller. The same episode had the local KFC restaurant shut down, resulting in all the kids going into KFC withdrawal and Cartman running a KFC ring by importing take-out from another town. Naturally, StatusQuoIsGod, and the marijuana store once again becomes a KFC restaurant at the end. Interestingly, the episode doesn't really show any ill effects from the drug. Instead, it's the ''length'' that the men go through in order to be able to buy it is over-the-top.
* Justified in the ''WesternAnimation/MajorLazer'' episode "Bad Seed" - the stash Penny smokes was laced with acid without her knowledge. [[AvertedTrope Averted]] in the rest of the series.
* ''Literature/TheLittles'' episode "Prescription for Disaster" does this with prescription painkillers. Our main characters visit a friend's home who lives behind the walls of a little girl whose mother is addicted to the drug, causing her to feel low-energy and irritable toward her daughter, which are fairly realistic side effects. However, Dinky accidentally gets a taste of the drug and starts hallucinating as if he were on acid. Perhaps a Little would experience different side effects from humans?

[[folder: Real Life]]
* Modern psychological research is starting to paint the picture that pot, while not normally hallucinogenic for a majority of people, can cause hallucinations in people with mental disorders which already makes them prone to psychosis, such as schizophrenia or bipolar disorder. Thus, this trope can be TruthInTelevision for a small percentage of people, although not for particularly good reasons.
** ''Contaminated'' marijuana can also have unpredictable effects, depending on the contaminant.
** Others use marijuana in moderation because it has a calming, steadying effect for them, better than some antipsychotic drugs, or say it helps those drugs to work better, even decreasing side effects.
** There is also ''spiked'' marijuana floating around. Some unscrupulous drug dealers (which aren't very scrupulous group to begin with) put other drugs in their weed so as the get people hooked on them. Hallucinogens are one of the more common drugs seen in the capacity.
** Ironically, some substances sold as [[http://en.wikipedia.org/wiki/Synthetic_marijuana synthetic marijuana]] are more likely to cause psychosis than marijuana itself.
* [[http://www.youtube.com/watch?v=hrZLc9lqQM0 This cop]] who baked pot brownies with marijuana [[DirtyCop taken from a perp]], ate half the pan, then called 911 because he thought he was dying. (For the record, while it is believed by some to be impossible to fatally overdose on marijuana, having a panic attack while under its effects can make you ''feel'' like you're about to die, and of course you can do stupid things under the influence that can get you killed.)
* In the early 1900s, [[https://en.wikipedia.org/wiki/Absinthe absinthe]] was LSD. It was blamed for corrupting children and causing criminal behavior and loose morals, the usual. In reality, absinthe is no more apt to be psychedelic than any other alcoholic drink. The ''amount'' in which it was consumed, on the other hand, was often more than enough to cause the alcohol psychosis. Remember that absinthe's heyday had come after the [[https://en.wikipedia.org/wiki/Phylloxera#Fighting_the_.22phylloxera_plague.22 phylloxera outbreak of 1863]], which made wine (the drink of choice for most of the affected population) scarce and expensive, so absinthe has come to be used as a substitute, and was drank accordingly despite being up to ''seven'' times more potent than common wines. Even when diluted, it was usually drunk with the copious amounts of sugar that masked its extremely high alcohol content.
* [[https://en.wikipedia.org/wiki/Datura_stramonium Jimson weed]] is a powerful hallucinogenic plant that is frequently confused with cannabis.
* The placebo effect is known to work most strongly on patients' thoughts and feelings, such as pain and nausea. As such, it is possible to induce hallucinations by dosing a subject with a substance that they believe to be a hallucinogen. The effect is even more convincing if the substance has any other psychoactive effects. Thus, marijuana ''can'' cause hallucinations - but only if the subject already buys into this trope.
