I've never met someone who abuses psychedelics for years and doesn't end up with some kind of induced schizophrenia. Now I don't care much about psychedelic users, if it helps with your health or spirituality or some shit it seems benign enough.
But I think tripping hard every day is bound to mess with your sense of reality and of self. It doesn't seem like Sprit Science has gotten any loonier over the years, however in this video ad for a retreat center in Costa Rica he says that he evolved into a higher place of leadership in his business thanks to it. And that Ayahuasca cured someone's cancer. He makes sure to put the cancer testimony about 50 minutes in after going on about how magical Ayahuasca is and shilling non stop for the slightly culturally insensitive retreat.

Retreat center: I mean call me cynical but it doesn't get any more cliché for a new age grifter than having partnered with Deepak Chopra.
