When comedian Shane Mauss was on the show in 2016, he and Marc talked about the new trajectory in his life that involved psychedelic studies. A year later, he lost his mind doing lots of hands-on experiments in that field of study. As Shane gets his standup act back on its feet, he tells Marc about the Roger Waters concert that landed him in a psych ward, the ways people get mentally exploited by motivational hucksters, and how he’s trying to strike a balance between opening his mind and letting his brain fall out.
