“Concerned by the misrepresentation of his work and the growing use of toad-derived 5-MeO-DMT with its consequent ecological repercussions, Ken came forward to explain his story and offer a sustainable way for humanity to interact with this invaluable compound. He died shortly thereafter, following a long battle with Parkinson’s disease. This updated edition of Ken’s original pamphlet was created to honor his contributions to science and his concern for the continued survival of the Sonoran Desert Toad.”
