I just thought I would bring this book to peoples attention. I bought it at a headshop in downtown Winnipeg. They had a variety of books on a variety of subjects, but their section on psychedelics was pretty darn good. I read the backs of all of them, and reads parts of some of them, and settled on Higher Wisdom. Turned out to be a pretty good choice. It interviews a lot of veterans of the psychedelic movement, and after reading it, you get a general sense of what this group of people thought these substances are capables of, what a psychedelic experience means, and overall it just seemed to deepen my interest in psychedelics and mind altering plants and drugs. Anyways, I highly recommend it. Higher Wisdom, edited by Roger Walsh and Charles S Grob.
