Stoners Are Funny

In the grand spectrum of media-depicted drug addiction, most junkies are seen as anything from piteous to terrifying. Tales abound of the superhuman strength of a PCP addict, or the despair of a crack addict, or the sheer horrors of a bad acid trip..

Not so much the pot smoker. Potheads are funny, mellow dudes interested in a good time wherein nobody gets hurt. Stoners are cool. They won't try to stab somebody because they think he's Dracula, or claw their eyes out because there are beetles in them. And it's not as if someone's going to complain, lest they get arrested for illegal drug use.

Examples of Stoners Are Funny include:

Comics

Matt MacLimore's stoner relative who pops up for a short period in Dork Tower and is never heard from again. His main claim to fame is smoking Matt's wargames terrain.

In Platoon, some stoners, including Johnny Depp, dancing with statues and "getting high". They're not so funny when it gets to fight.
In Jackie Brown, Melanie sure fits in. Louis didn't like it.

Live Action TV

The main cast (but especially the four guys) in That '70s Show. Scenes showing them smoking pot (called the Circle) occur in every episode.
- That goes double for Leo.
How I Met Your Mother often uses this trope when it flashes back to the Main Characters' college years, though The Narrator always refers to the activity they take part in as "eating a sandwich," complete with the joints transformed into hoagie sandwiches.

Video Games

The Truth in Grand Theft Auto: San Andreas.

Web Comics

Subverted in Homestuck, where Gamzee Makara (who is The Stoner, but from a Fantastic Drug) is treated this way at first. Later, he runs out and realises the drug was actually rotting his brain, and in addition to having his religion mocked, this makes him flip his shit and become an Omnicidal Maniac Monster Clown.
Sweet Bro and Hella Jeff plays this every so often, or at least tries to - we wouldn't really know if not for the stooned imagery everywhere. SUDDENLY WEED DREAMS.
Main Premise of Drugsand Kisses

Web Original

That High, which is basically FML, but for stoners instead of unlucky people.
The Onion article Everyone Involved in Pizza's Preparation, Delivery, Purchase Extremely High.
- Resident columnist Jim Anchower.
Chester A. Bum often gives hints on being a stoner.

Western Animation

Shaggy from Scooby Doo may or may not be an actual stoner, but how can people not jump to that conclusion? He's always hungry (he eats dog treats, for crying out loud), he's always freaking out over monsters, he thinks his dog (Scooby) can talk, and he even looks and speaks like a hippie stereotype. Talk about Getting Crap Past the Radar.
- William Hanna And Joseph Barbera patterned the Scooby-Doo characters after the characters in The Many Loves of Dobie Gillis, a 1950s sitcom featuring Dawson casted "teenage" characters. Shaggy is an Expy of Maynard G. Krebs (played by a pre-Gilligan's Island Bob Denver), the show's resident beatnik. Freddy was Dobie, Velma was Zelda, and so forth. Not sure if drugs factored in either Shaggy or Maynard's lifestyles, but being "laid-back" didn't start with hippies. Of course, it being a 1960's cartoon with already ten-year old pop cultural references doesn't help matters...
Otto the bus driver from The Simpsons (though signs that he does drugs—particularly marijuana—didn't crop up until season seven. Prior to that, he was just some perpetual teenager who drove a school bus [despite not having a license], got along great with kids, and loved rock music from the 1960s to the 1980s).
Trent & Jesse. Especially Jesse.
