A few of my favorite books:
Trainspotting
Christiane F
A Million Pieces
Fight Club
Fear and Loathing in Las Vegas...book is better IMO
Smack
Junky Love
Candy: A Novel of Love and Addiction
Dopefiend
Drugstore Cowboy
The Basketball Diaries

Well I can't think of too many more right now...but all of those I highly recommend.
