The Psychedelic Gospels: The Secret History of Hallucinogens in Christianity, by Brown, Jerry B., PhD, and Julie M. Brown, MA. Park Street Press, 2016.
I have not read this book but have added it to my to-read list. I'm intrigued about the role of edible plants in the formation of our beliefs and religious systems. I would like to learn more about the relationships among the mystical, the psychadelic, and the religious.
