In this conversation with Dr. Peter Grinspoon — Harvard Medical School instructor, primary care physician, and board-certified addiction specialist at Mass General — we have a wide-ranging, refreshingly honest conversation about cannabis, addiction, and the messy human truths in between. Peter opens up about losing his medical license to a prescription painkiller addiction, coming from a family legacy of cannabis advocacy (his father wrote the influential 1971 book Marihuana Reconsidered), and why he believes legalization — not just decriminalization — is the only coherent path forward. We get into the real benefits and real harms of cannabis, who should avoid it, the dangers of over-concentrated products like 7-OH kratom, and why he'd rather see people support the mom-and-pop dispensary over the corporate cannabis conglomerate.
