I am almost done reading Realms of the Human Unconscious: Observations from LSD research by Stanislav Grof, and I think it is one of the best books ever written about LSD. If you are interested with LSD and psychology, you should read this book. The author conducted more than 2,500 hours of clinical research with LSD involving psychiatric patients as well as healthy individuals. The book is mainly about his observations from psycholytic and psychedelic observations. With all of the misinformation out there about LSD, this is a good book to have.
Tiz a cool book left me thinking for many days after. Try Beyond The Brain by the same guy. Another classic!
very good book,i have read it 3 times now,the holotropic mind is also a good book, Dr stan Grof is a genious.
