There's this dude's stuff http://www.lulu.com/newport

He's a stoner and a fan of HST, Bukowski, Vonnegut, and Phil Hendrie.

I ordered his books one at a time and each arrived in a week.

They are easy to read and some of the chapters are hilarious because the dude just explodes with amazing venom and vitriol. And then the chapters about why we exist and what happens after death really strike me curious and make me smile with a raised eyebrow. There's no one else like him. Can't praise him enough.

If that don't float your boat then check out Post Office by Charles Bukowski.
Or Slaughterhouse-5 by Kurt Vonnegut.
Or Catch-22 by Joseph Heller.

Mind you, those aren't written by stoners nor are they about stoners, but I've never known a stoner who didn't like them. Classics.
