This is a long, highly recommended list of heroin/opiate related books with a short review on each. A similar list of books was also posted by the same person (?) on drug/opiate forums (check google).
I'm not sure if I can post the whole thing, but here's an excerpt:
Junky
By William Burroughs. autobiographical account of his own life as a junkie. book takes place right after world war 2, so the middle 40’s. i highly recommend it. he talks about what it was like to be a junkie then in junkie terms and he also talks about withdrawal. Classic heroin boook
Naked Lunch
By William S. Burroughs. Published in the US in 1959, six years after his first book, “Junkie,” which was initially ascribed to “William Lee,” this is Burroughs’ masterwork–laying out the themes he so obsessively pursued throughout his entire long writing career. (Burroughs died in Lawrence, Kansas, in 1997 at age 83, drinking and toking up to the end.) This is something of a difficult book: parts of it are extraordinarly gross and the novel lacks formal narrative structure. It is also hilariously funny and truly captures the paranoid drug mind so epitomized by Burroughs’ entire philosophy. Highly recommended, along with “Junkie,” posted above by Psychobabe. All Burroughs’ major works are available in Penguin paperbacks.
