There's a point in the Bill Hicks movie where dying form cancer he takes magic mushrooms and with his friend has an ET contact moment. I mention it because McKenna talked about his experiences many times but here he outlines the science for why Psilocybin makes a more credible case for ET contact than the pedestrian attempts of scanning the cosmos for radio waves. It's not only a wilder theory than his stoned ape rap (which was always about encouraging people to explore conciousness) it's better.
