“Most readers of this book will likely belong to that unusual set … who need no convincing of the value of psychedelic drugs. There will be others — not in the choir, not even in the congregation of true believers — who will greet this book’s birthing with bafflement, shock, or even anger.”
– Daniel M. Perrine, Loyola College

“This book not only reveals how psychoactives can be synthesized, but also how they can be extracted from so many ordinary plants that the means for psychedelic exploration can never be controlled again. The genie is out of the bottle and all the king’s horses and all the king’s men cannot put it back again.”
– Nicholas Saunders, London
