Culture - Films- amphetamine use and drugs in general

[MissPoppy485]

I know alot of us, and our friends of friends, have seen 'Spun' and the reactions seem quite mixed. I found it quite disturbing at the time, but must admit it had some excellent moments (I was very amused by the green dog incident). I was just curious as to what other films related to drug use, speed in particular, you've come across and if they're worth a look. Incidentally, I'm currently reading 'Porno', the sequel to 'Trainspotting' and it's possibly even better. Any recommendations film wise would be much appreciated xx
