This movie has a twist in it so I don't want to give it away. Basically the movie is about Crank, Crystal, Meth -whatever you want to call it. It's more than a drug culture movie though -it has some insights into human nature that are interesting.
It stars Val Kilmer as a speed freak/police informant who hangs out with some losers and busts various scumbags.
Basically the movie starts when the police he works for -cut him loose. He then tries to score one last time with a meth cook known as "Pooh Bear" -so called because he has no nose. (So named because Winnie the pooh got his nose caught in a honey jar.)
Anyways it's a good movie and I recommend it.
