I don't know if this was already mentioned, but for one about meth, Spun is a very interesting movie. It was pretty good, although there isn't much of a story line to it. But it does a good job of portraying what happens to people who are involved in the meth scene. There's one main character and you are introduced to a bunch of other characters, but by the end something different happens to each one. Definitely worth the watch.
