In October 2013 a conference on psychoactive plants and their use was held at the University of the Witwatersrand. The main speaker was Graham Hancock, whose second talk is viewable below. Scroll down for more talks from the conference.
Kilindi Iyi from Detroit, below, Master of martial arts, amongst other things, is an impressive speaker and someone who has 'gone to the edge'. I found his 'Ice Age' theory both plausible and comforting, but I'm not up to eating thirty grams of dried anytime soon :-)
Monica Kromhout, below, South Africa's very own shroom granny, telling it how it is. Unfortunately, Monica is at the current moment defending herself against charges of possessing a large quantity of magic mushrooms that could land her in jail for some time. We encourage you to sign the petition for clemency in her landmark case against the state, currently proceeding as of 5/3/15.
