psychedelic classic

The author accidentally drowned in his bath tub at a young age. Ketamine supposedly played a role in this accident. As to his two books I think they're great if you are interested in psychedelic drugs they are classics.

You can read the essential psychedelic guide online if you do a search.
If you are interested in experiencing altered states a great hobby is yoga.

Overpriced and overrated!

When this book was available at every bookstore for a few bucks, it was worth a read... but for a super-thin book (a glorified pamphlet, really) that is full of factual errors, it's simply absurd to see it selling for over a hundred dollars. Sure, its out of print. If you're a book collector with too much money, maybe that would make it worth the price... but thats really the only thing going for it. Wait for a reprint, or better yet, buy a different book that has a higher quantity and quality of information.
