Exploring Microdosing LSD & Psilocybin

In this 2025 interview with Justine Willis Toms, James Fadiman, Ph.D. and Jordan Gruber, J.D. discuss protocols, the legality, safety, and other facts about microdosing. Microdosing involves taking small amounts of psychedelics such as LSD and psilocybin mushrooms, typically every other day, to enhance physical health and cognitive function. Research, including participatory citizen first-person accounts, indicates that microdosing has alleviated symptoms of depression, ADHD, chronic pain, long COVID, and many other ailments.

James Fadiman, Ph.D. is a former president of the Institute of Noetic Sciences and professor of psychology. He has been professionally involved with psychedelics for more than 60 years and has been exploring the practice of microdosing psychedelics in depth, drawing on new research and extensive personal accounts from individuals worldwide. He has developed the use of protocols.

Jordan Gruber was awarded a J.D (Juris Doctor) degree, and has forged and sculpted authoritative volumes in forensic law. He has written, ghostwritten, and edited more than a dozen books in a wide variety of fields, including psychology, spirituality, finance, and personal development.
