"Move over, ayahuasca. Looks like the magic toad ride is the next big thing for entheogenic explorers"

-- Don Lattin, bestselling author of The Harvard Psychedelic Club.

"The author has had an astounding and intense life that he shares in his gentle and honest story. Most serious psychedelic explorers remain fixated on the psychedelic that first opened them to larger consciousness. Few people have had as much, as varied, and as meaningful psychedelic experiences. Given the sheer volume of his experiences, as he himself says, most people would've become insane. Instead, he became a practicing physician and now divides his time between his medical practice and helping people make the best possible use of the short acting, most powerful entheogen, 5-MeO-DMT. His teaching is a gift, as is this book about it."
