From the podcast episode:

“Phil Wolfson has been a friend of mine for over a decade. In addition to being an absolute genius and one of the most generous people I’ve ever met, Phil has been at the forefront of the psychedelic psychotherapy world for the better part of 50 years. We go into his work with MDMA with couples during its legal period, his use of Ketamine and some general history on the use of psychedelics in psychotherapy both legitimate and in the underground.”
