In this episode of the Radical Responsibility podcast, host Fleet Maull interviews psychedelic researcher James Fadiman. Fadiman recounts his early involvement with psychedelics at Esalen and Stanford, describing how a series of personal psychedelic experiences in the 1960s redirected his career toward psychedelic research. He explains the landmark Stanford study that attempted to use psychedelics for scientific problem‑solving, the abrupt FDA shutdown, and how that episode sparked a wave of citizen‑science microdosing reports from dozens of countries. The conversation moves to the development of the "Fadiman protocol" (one dose every three days) and compares it with other regimens such as Paul Stamets’ stack and various on/off schedules. Fadiman details the therapeutic signals emerging from thousands of self‑reports—reductions in depression, anxiety, pain, and other forms of "disequilibrium"—and notes that microdosing appears to lower negative affect while raising positive affect, unlike many SSRIs. He touches on neurophysiological findings (increased brain‑wave amplitude at lower levels than full doses) and argues that placebo effects are built‑in to psychedelic research, but microdosing’s self‑administration reduces placebo confounds. Regulatory hurdles are discussed, including the FDA’s recent rejection of MDMA approval and the limited role of double‑blind designs. Fadiman predicts a future where microdosing becomes a regulated supplement, driven by citizen demand, and announces his upcoming book, Microdosing for Health, Healing and Enhanced Performance, which compiles real‑world evidence and outlines practical guidance. Throughout, the tone is conversational, enthusiastic, and cautiously optimistic about the therapeutic potential and societal integration of microdosing.
