Jay and Silent Bob (doesnt get nearly enough respect) almost everyone loves grandmas boy Fear and loathing theres probably millions of posts bout movies on here, you could find some awesome lists
Harold and Kumar go to White Castle Either way, I don't know if it's a good idea to just seek out movies that have a marijuana reference or two in them. Just get stoned and watch a movie that you think you'd enjoy, it'll be THAT much better.
Fuck man I love this movie. Watched it last night and had to go to top notch hamburgers since I live right by where that was filmed. haha
Blow, Scarface, Paid in Full, Alpha Dog, Half Baked, How High, Training Day, Super Troopers, Dazed and Confused, Superbad, Cheech and Chong, Friday, Next Friday, Friday After Next, Harold and Kumar Go To White Castle, Eurotrip, Miami Vice, Without A Paddle, Don't Be a Menace, American Gangster, Reefer Madness, Rolling Kansas, Fast Times at Ridgemont High, Bongwater, Jay and Silent Bob Strike Back, Knocked Up, ummmmm.....that's all I can think of right now
Saving Grace is about a middle aged widow who grows pot in a greenhouse to save her home from foreclosure. Great movie set in Ireland.
