Few people in history manage to make their way to the status of cultural legend.

Terence McKenna

Among them, I propose, at least in the psychedelic culture, is Terence McKenna. The man who, according to writer and modern-mystic James Oroc, helped keep the psychedelic culture alive during the major acid drought of the 1990s by bringing our attention to the transdimensional potential of plant psychedelics.

During his heyday, Terence played no small part in the popularising of DMT, ayahuasca, and psilocybin mushrooms. This is an attribution that stays strong even today, 17  years after his death. His ideas, his voice, and his influence are still palpable through the thousands of hours of McKenna’s recorded talks online. His eloquent and engaging stories of deep jungle journeys, machine elves in hyperspace, and encounters with unimaginable novelty as well as his philosophies on culture, realty, and the nature of mind has ascended him to legend status. But a legend is never the truth. It always obscures the facts in favour of fancy.

How do we discover the truth when the man of legend is dead? Well, we could start by asking his brother, Dennis.

The McKenna Brothers. (Dennis on the left, Terence on the right.)

Terence was a trailblazer, but not exclusively on his own. The legend of Terence McKenna is really the legend of the McKenna brothers. Together, both of them went down to la chorerra in search of plant psychedelics, both of them contributed to the widespread availability of psilocybin mushrooms through the development of home cultivation techniques, both of them went on to dedicate their lives to the study of psychedelics.

The thing is, while Terence got on a stage and gathered crowds, Dennis buried himself in academia; while Terence was waxing poetic on philosophical implications of DMT, Dennis was doing ethnobotanical research on DMT containing plants and biomedical research on the physiological effects of ayahuasca; while Terence was selling out speaking events, Dennis was publishing peer-reviewed research papers. Terence sadly died in 2000, Dennis is still with us, and is in fact, with us directly on this episode of Adventures Through The Mind.

Dennis McKenna

Formally, Dennis Jon McKenna (born December 17, 1950 in Paonia, Colorado) is an American ethnopharmacologist, research pharmacognosist, lecturer and author. He is a founding board member and the director of ethnopharmacology at the Heffter Research Institute, a non-profit organization concerned with the investigation of the potential therapeutic uses of psychedelic medicines.

McKenna received his Master’s degree in botany at the University of Hawaii in 1979. He received his doctorate in botanical sciences in 1984 from the University of British Columbia, where he wrote a dissertation entitled Monoamine oxidase inhibitors in Amazonian hallucinogenic plants: ethnobotanical, phytochemical, and pharmacological investigations. McKenna then received post-doctoral research fellowships in the Laboratory of Clinical Pharmacology, National Institute of Mental Health, and in the Department of Neurology, Stanford University School of Medicine.

He is one of the founding contributors to the modern wave of ayahuasca research in particular and psychedelic research in general. In fact, the book Magic Mushrooms grower’s guide, which he co-authored with his brother Terence in the 70s, presented the first reliable method for cultivating psilocybin mushrooms at home.

Chances are if it wasn’t for Dennis and his brother, none of us would have ever tasted the magic at all.
It was an absolute honour to talk with him. Enjoy.
