Tribute to Lester Grinspoon - with special guests David Grinspoon, Keith Stroup, Allen St. Pierre, Valerie Leveroni Corral, and Rick Cusick (Ep. 5). In this special extended episode of Cannthropology, we honor the passing of the “Godfather of Medical Marijuana” Dr. Lester Grinspoon. To memorialize his life and legacy, host Bobby Black welcomes on some of those who were closest to the good doctor: his son, astrobiologist and author David Grinspoon; NORML founder Keith Stroup, former NORML executive director Allen St. Pierre, WAMM cofounder Valerie Leveroni Corral, and former High Times associate publisher Rick Cusick, who all share some of their favorite memories, anecdotes, and insights into one of the consequential advocates in the cannabis community.
