So, sometimes the writer wants to show a character acting stoned, drunk or hallucinating for the purpose of comedy. When the character in question is a cat or other feline, the "drug" of choice will often be plain ol' catnip.
This has several advantages. For starters, it prevents the writers from having to put any "real" drugs into the story to get the desired result, and secondly, for talking or humanoid felines, it serves as a Furry Reminder, giving an otherwise human-acting animal a realistic behavioural quirk for their species. Such a scene can also be used to avert the snobby, uptight stereotype often associated with cats.
If you really want to sneak past the radar, show Anthropomorphic cats smuggling/hiding catnip as if it were an illegal drug. If a normal human can get high off the stuff, it may serve to enforce an Animal Motif or give an impression of general quirkiness.
This is Truth in Television. Catnip can have a soothing effect on humans and has often been brewed into tea and, yes, even smoked. It is a muscle relaxant, and catnip and hop brew makes a good sauna water additive.
- Was part of a Christmas-themed Petco commericial a few years back.
Cat: I smell catnip!
Dog: Don't inhale!
Cat: Too late... whooo!
- The Pokémon anime featured this with "poké-nip." Ash's Bulbasaur smelled some in one episode, at which point it got a big, goofy grin on its face, walked over to Ash and nuzzled against his legs.
- Queen's Blade: Hide 'n Seek. Done to Elina by Nyx to comedic effect when she surprises her with catnip powder, after learning Elina was susceptible to it. The accompanying flashback even reveals that her sisters used to use it to keep her under control. Sadly for Nyx, it backfires when Elina rapes her while under the influence.
- In Hyper Police catnip tea is Natsuke Sasahara's usual choice of intoxicating beverage.
- A filler episode of Inuyasha has a villain incapacitate Kilala with catnip. Some translations use Silver Vine (Actinidia) instead, an Asian plant with a similar effect upon felines.

- Ranma ˝:
- Despite being human, Ranma is just as susceptible to catnip as any other cat while under the trance of the Cat Fist/Nekoken (which turns him, mentally, into a cat.) It once stopped his berserk rampage at school and made him playful and affectionate... too affectionate, as he happily leapt into Akane's lap and rubbed his face against hers, giving her a mock "kiss" in front of the entire school.
- In another story, Maomolin the giant Ghost Cat wants Ranma to stay away from the Cat Shrine, where he's holding Shampoo captive until he can turn her into a cat. So, he brings gifts to the Tendo home and breaks a capsule of a mysterious powder that covers Ranma. Maomolin goes into a brief high, but Ranma and Akane don't notice that the powder was catnip essence until they're assailed by dozens of cats.
- Later in the story, Ranma stuffs a coat with catnip in order to draw away the hordes of cats while he rescues Shampoo. When Akane questions The Plan, considering Ranma's ailurophobia, he promptly puts the coat on her so she pulls the cats away while he goes and kisses Shampoo (long story.) Annoyed, Akane puts the coat back on him, tosses him at the cats, and simply takes the cat-covered coat off him and tosses it away to get rid of the felines.
- One chapter of Omamori Himari has samurai catgirl Himari take a catnip-based medicine to recover from some injuries. The drug reverts her mind to an animal state and she spends the night trying to play with Yuuto.
- In Rosario + Vampire, Shizuka Nekonome has been occasionally seen with a bottle of 'catnip wine'. Her behaviour during such times... predictable.
- Eris in Cat Planet Cuties accidentally got into some catnip. Considering that it made her hyper (well, more hyper than usual) it came across as being closer to an analogy for cocaine than pot.
- In Captain Carrot and His Amazing Zoo Crew!, Alley-Kat-Abra/Felina Furr actually gets a catnip high, tells her team-mate Captain Carrot/R. R. Rabbit that he is "really cute, but would be cuter if he was a cat," uses her magic powers to turn him into one, and offers him some catnip. No, this comic wasn't from Vertigo...
- In American Flagg!, while serving as mayor of Chicago, Raul (an actual cat, albeit an intelligent talking one) becomes addicted to Gato Blotto™, a super-potent variety of catnip.
- The Fabulous Furry Freak Brothers: Fat Freddy walks in with a little plastic bag full of crumbled leaves - his cat sniffs it and starts leaping and cavorting with delirious joy. Freddy bawls "I spent my last fifteen dollars on catnip!"
- Used several times in Garfield. One early Sunday strip takes a more literal approach to this: Garfield (looking visibly stoned) silently stares at his waterbowl as strange things appear entering and exiting it. The last panel has Garfield saying "That was some good catnip". Not surprisingly, the strip was never published after the comic premiered in 1978, though it was featured in the 25th anniversary book for the series.
- Get Fuzzy has this a few times.
Bucky: Have you ever, like, really looked at your paws? Like, really looked at them? Whoaa...
Rob: Bucky get into the catnip again?
Satchel: Yeah, he's kinda loopy right now.
- This is a periodic source of humor in Krazy Kat.

- A scene in Cats & Dogs 2: The Revenge of Kitty Galore has the heroes visit the house of a Crazy Cat Lady. Turns out a) cat ladies are such enablers for catnip addiction, b) cats on catnip act like comedic-variant stoners.
- Catwoman has a scene where the titular character reacts very... strangely to catnip.
- In Tailchaser's Song, Tailchaser has never seen catmint before but comes across a patch. Being strangely attracted to it, he ends up eating a lot of it. Afterwards Tailchaser overdoses, passes out, and has a weird dream. Most other cats ignore him and simply think he's a dunce who likes catmint too much, but Tailchaser's kitten friend Pouncequick freaks out thinking Tailchaser is dying.
- Warrior Cats:
- Warrior Cats pretty much averts this. It appears in the books and is used as a medicinal herb to help cats with greencough/pneumonia relax (though Fireheart in the first series remembers it from when he was a pet kitten and is extremely tempted to bite down on it when carrying some back). The authors have commented that, while they touch upon several serious topics in the series, one that will almost certainly never appear is drugs in any form.
- In Moth Flight's Vision, it finally gets played straight. Moth Flight, having never used catmint before and no idea what the proper dose is, guesses and ends up giving Rocky too much. The old cat gets high and plays like a kit, and tries hilariously to find any excuse to get some throughout the rest of the book.
- There's a brief mention near the start of The No. 2 Feline Detective Agency of a hippy commune of cats who were growing catnip but were able to show the authorities it was for personal use.

- In Bewitched, a female cat is turned into an attractive young woman, who gains the attention of another young man before Samantha can change her back. Samantha 'spikes' the cat's drink with catnip, and the resulting intoxication (and angry hissing when the young man takes it away) is enough to cool his ardor.
- Knights of the Old Republic parody art sometimes involves getting Juhani good and baked on nip, usually in the context of Revan trying to take the edge off her temper.
- Hazama's gag reel in BlazBlue: Continuum Shift has him bathing in Spanish catnip. While Hazama himself isn't affected by it, when he goes to the Kaka village to cause some trouble, every one of its inhabitants exhibits strange behavior, as if getting high off the aroma. And then Jubei and Kokonoe get involved, and his cat allergies start to catch up. Things only get more wack from there...
- Catnip appears as a consumable item in the Postal series. In both Postal 2 and Postal III, The Dude can smoke it, creating brief Bullet Time. In Postal III, it can even be sprayed on cats in order to catch them.
- Played with in an episode of Cat Face. The title character rubs himself against some catnip, following with a close-up of his dilating eyes and psychedelic music, implying he's going on a trip. Then it automatically zooms out and Cat Face tells Box Cat to stop playing the "crappy music". After yelling at his friend, Cat Face flies up and purrs until he runs into a lit lightbulb. It Makes Just As Much Sense In Context.

- Questionable Content: Apparently, Dora's cat Mieville in this strip.
- This episode of Talking Kitty Cat. He tears open a small bag of catnip and sometime later goes completely catatonic, with visual effects simulating a catnip trip.
- Played straight in the 'Fionna and Cake' episode of Adventure Time. Cake is handed a bag of catnip, and she sniffs it, after which her pupils dilate and she remarks, "SWEET BABIES..."
- Parodied in the "Cat Orgy" episode of South Park. Mr. Kitty brings her tomcat friends in the house, dumps catnip on the floor, and one of the cats snorts it. And then... Well, see the episode's title.
- In Codename: Kids Next Door, catnip causes the Cat Lady's cats to have a sudden dance party.

- Catnip works on the feline brain similarly to how marijuana works on the human brain. However, the effects are much more short-lived. Some rare cats are naturally immune to its effects though, and even normal cats will become immune for a while if they're constantly exposed to it. It also has a calming effect on humans, and is a common ingredient in "calming" teas. It's not as pronounced, but the chemical effects are similar to how it works on cats. And yes, catnip does have that effect on the larger cats like tigers, lions, leopards and pumas.
- Valerian (the herb) has the same effect as catnip. In some countries such as Russia, valerian is the cats' drug of choice in popular perception. Especially because it is readily available in drugstores as an over-the-counter anxiolytic, hence, cats can readily obtain valerian from their masters' closets.
