Stoner movies are an under-appreciated film genre. Some of the funniest and interesting movies have revolved around the world of tokers. But even with marijuana becoming legal in many states, the stoner genre remains under-utilized.

To try and prompt Hollywood to make more of them, here are the highest grossing (based on U.S. box office) stoner movies of all-time. Data is from Box Office Mojo, although I removed all the “slacker” movies since those aren’t quite the same. Also, all totals are not adjusted for inflation.

15. A Very Harold and Kumar 3D Christmas (2011), $35,061,031

Fast Times at Ridgemont High, The Big Lebowski, Dazed and Confused, Clerks and Mallrats are all great, classic stoner movies. All of them grossed less than this garbage movie.

14. 30 Minutes or Less (2011), $37,053,924

30 Minutes or Less is the rare time where the filmmakers took the concept for a mediocre thriller movie and turned it into a mediocre comedy. Truly groundbreaking.

13. Bill and Ted’s Bogus Journey (1991), $38,037,513

Has any actor had a more unusual career trajectory than Keanu Reeves? Starts off as a stoner comedy star, becomes an action movie star, devolves into Hollywood’s most mocked actor, and then comes back as an action star again with the John Wick movies. He’s had a heck of a career.

12. Harold and Kumar Escape from Guantanamo Bay (2008), $38,108,728

The original Harold and Kumar was hilarious stoner comedy that became a cult classic. Unfortunately it didn’t gross as much as its fairly unfunny followup.

11. Bill and Ted’s Excellent Adventure (1989), $40,485,039

Time travel was major plot point in 1980s movies. Back to the Future, The Terminator, Time Bandits and many more helped create the genre. Bill and Ted’s perfected. Well, Back to the Future perfected it, but Bill and Ted’s was just as good.

10. Cheech and Chong’s Next Movie (1980), $41,675,194

Any list of stoner movies has to include Cheech and Chong. The guys practically invented the genre! You’d think in an era where Hollywood reboot every classic movie AND marijuana is actually legal in some places that Cheech and Chong would get a new movie. But knowing Hollywood, they’d probably reboot it with Harry Styles as Cheech and some unknown male model as Chong.

9. Up in Smoke (1978), $44,364,244

The movie that made Cheech and Chong America’s most popular stoners.

8. Dude, Where’s My Car? (2000), $46,729,800

Considering the number of jokes inspired just by the title of this movie alone, you’d think this would be number one.

7. Next Friday (2000), $57,328,603

The second movie in the Friday franchise starring Ice Cube was the highest grossing in the series. Proof Ice Cube can do more than rap.

6. Beavis and Butt-head Do America (1996), $63,118,386

Probably every Mike Judge movie would make a list of the best stoner movies ever. Unfortunately, most of them were box office bombs although Beavis and Butt-head did enough to make a spot on this list.

5. Road Trip (2000), $68,540,777

Three years before he made Old School, Todd Phillips directed Road Trip, a movie about four college friends traveling across the country to recover a sex tape. Old School was better.

4. Pineapple Express (2008), $87,341,380

The movie that united two of Hollywood’s greatest stoners, Seth Rogen and James Franco, in a movie that’s legitimately about the world surrounding pot. If the movie were made today, Frnaco would just be living in a Colorado working at his own dispensary.

3. This Is the End (2013), $101,470,202

It’s definitely the best stoner, post-apocalyptic movie/celebrity cameo showcase ever.

2. Knocked Up (2007), $148,768,917

Not surprising that the movie that launched the career of one of Hollywood’s greatest stoners (Seth Rogen) would wind up pretty high on this list.

1. Ted (2012), $218,815,487

Seth MacFarlane plays a teddy bear that grows up to be the pot-smoking buddy of Mark Wahlberg. A decent movie, but hardly the best stoner movie of all-time.
