Dennis McKenna's professional and personal interests are focused on the interdisciplinary study of ethnopharmacology and plant hallucinogens. He received his doctorate in 1984 from the University of British Columbia, where his doctoral research focused on ethnopharmacological investigations of the botany, chemistry, and pharmacology of ayahuasca and oo-koo-he, two orally-active tryptamine-based hallucinogens used by indigenous peoples in the Northwest Amazon. He is a founding board member of the Heffter Research Institute and serves on the advisory board of non-profit organizations in the fields of ethnobotany and botanical medicines. On today's episode of Bulletproof Radio, Dennis and Dave talk about psychopharmacology, DMT and the drug culture in the '60s, psychedelic conspiracy theories, microdosing, rescheduling psychedelic drugs, his pursuit of Ayahuasca with the Witoto people and more.
