Anyone read The Electric Kool-Aid Acid Test by Tom Wolfe? It's pretty much a true story and is like a history of early acid use.

The acid tests were huge parties thrown by Ken Kesey(he wrote One Flew Over the Cookoo's Nest) and his friends, the Merry Pranksters, back in the late 60's. The Grateful Dead got their start playing at those parties. Anyhow, several thousand people would show up and everyone would be given a glass of kool-aid dosed with high quality acid. The Dead would play and everyone would trip their balls off.

Of course the book is about a lot more than just the acid tests specifically and goes into pretty much the whole late '60's San Francisco drug scene. It's pretty funny and definitely a good read . I would think a must for anyone on this board.
