My guest this week is author, Mike Marinacci, discussing his just-released book, Psychedelic Cults and Outlaw Churches: LSD, Cannabis, and Spiritual Sacraments in Underground America. It's a fascinating historical read and brings to light both well known and obscure religious movements in the US where psychedelics have been used as part of religious practice, covering from the formation of the Native American Church all the way up to internet religions in 2021.
