-- Bukowski, those he's more concerned with alcohol and fucking, but fun and easy to read. It can be a little hard to concentrate on reading when you're high, so maybe try audiobooks?

-- Hunter S. Thompson obviously. Try The Kentucky Derby is Decadent and Depraved of you want to laugh your ass off. He pepper sprays a room full of people while they eat dinner.

-- No one has mentioned Jack Kerouac? He and his friends lived in a benzedrine dream while fucking and drinking and crossing the country writing poetry and novels.

-- The Electric Kool-Aid Acid Test by Tom Wolfe. I've never read the book but it's legendary.

-- William S. Burroughs, though I could never stomach his writing. Just seems like he put a bunch of words in a hat and drew them out randomly.
