I've not seen or heard 'Requiem For A Dream' but just watched trailer now and downloading it. Looks mental!

My favorites:
Trainspotting - Heroine
Scarface - Cocaine
Pineapple Express - Marijuana
Fear and Loathing in Las Vegas - a good mix of everything
Others worth mentioning:
Pulp Fiction
Lock, Stock and Two Smoking Barrels

harold and kumar trilogy
cheech n chong collection
how high
half baked
pulp fiction
will add more when i think of them

if you like movies with drugs you will also enjoy the tv show: Breaking Bad. I've seen all the seasons twice and I loooove it!

I forget

Pineapple express, friday, friday after next, the hangover

From all the drug movies I've seen....they are, for the majority, crap. Cinematography has become a joke, in my opinion, and movies pandering to people eager for cheap drug-related jokes are often low-brow comedies with no true value.
Except Scarface. That was actually rather good.

Up in Smoke -cheech and chong
Best movie i ever saw stoned :)

Trainspotting i thought was good and i love the film how high
