Synchronicity numero cinco features the extraordinary Dennis McKenna. Dennis McKenna is an American ethnopharmacologist, research pharmacognosist, lecturer and author. He is the brother of well-known psychedelics proponent Terence McKenna and 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.

Dennis is also one of the smartest people I've had the privilege of speaking with (this is Noah writing in case that isn't abundantly clear by now). We talk about a variety of topics including the benefits of psychedelics (DMT, Ayahuasca, Psilocybin, Cannabis), plant intelligence, the unconscious, and ethnopharmacology at large.

As we discussed Dennis has written an incredible autobiography called "The Brotherhood of the Screaming Abyss." Get it here: http://www.amazon.com/Brotherhood-Screaming-Abyss-Dennis-McKenna-ebook/dp/B00A8KWLYK/ref=sr_1_1?ie=UTF8&qid=1448424968&sr=8-1&keywords=brotherhood+of+the+screaming+abyss
