Dennis McKenna has been about as deep into the psychedelic realm as a psychonaut can get. But growing up in Paonia, Colorado he and his brother Terrance had to keep all that on the DL. In the decades since he's not only been a leading voice in the psychedelic activism and advocacy worlds, he's an ethnopharmacologist, author, professor and heady conversationalist. He joined Rooster shortly after the Psychedelic Science Conference 2023 for a conversation about our mushroom-hungry ancestors, the merging of ancient practice and modern science around psychedelic therapy, and his  ethnobiological research school, the McKenna Academy.
