The book Tweak: Growing Up On Methamphetamines by Nic Sheff is a beautifully written memoir of a struggling Meth addict. It was lent to me by a friend and I finished it in two days. I have to admit, it made quite an impact on me. I recommend it to anyone over the age of 16 (it is very graphic and explicit). Has anyone else here read it? If so, did it affect you in any way?
