Dennis McKenna - The Depths of Ayahuasca: 500+ Sessions, Fundamentals, Advanced Topics, Science, Churches, Learnings, Warnings, and Beyond | Brought to you by Wealthfront automated investing, Allform premium, modular furniture, and Tonal smart home gym. More on all three below.

Dennis McKenna (@DennisMcKenna4) has spent more than 40 years researching the interdisciplinary study of Amazonian ethnopharmacology and plant hallucinogens. He has conducted extensive ethnobotanical fieldwork in the Peruvian, Colombian, and Brazilian Amazon.

His doctoral research at the University of British Columbia focused on the ethnopharmacology of ayahuasca and oo-koo-he, two tryptamine-based hallucinogens used by indigenous peoples in the Northwest Amazon.

He is a founding board member of the Heffter Research Institute, and was a key organizer and participant in the Hoasca Project, the first biomedical investigation of ayahuasca used by the UDV, a Brazilian religious group. He is the younger brother of Terence McKenna.

From 2000 to 2017, he taught courses on ethnopharmacology as well as plants in human affairs in the Center for Spirituality and Healing at the University of Minnesota. In 2019, in collaboration with colleagues, he incorporated a new non-profit, the McKenna Academy of Natural Philosophy. He emigrated to Canada in the spring of 2019 together with his wife Sheila, and now resides in Abbotsford, B.C.
