This episode I discuss medical research on psychedelic compounds with Dr. Matthew Johnson, Professor of Psychiatry and Behavioral Sciences at Johns Hopkins School of Medicine. We discuss the biology and medical clinical-trial uses of psilocybin, MDMA, ayahuasca, DMT, and LSD. Dr. Johnson teaches us what the clinical trials in his lab are revealing about the potential these compounds hold for the treatment of depression, addiction, trauma, eating disorders, ADHD, and other disorders of the mind. Dr. Johnson describes a typical psychedelic experiment in his laboratory, start to finish, including the conditions for optimal clinical outcomes. And he explains some of the potential hazards and common misconceptions and pitfalls related to psychedelic medicine. Dr. Johnson explains flashbacks, the heightened risks of certain people and age groups using psychedelics and the ever evolving legal and pharmaceutical industry landscape surrounding psychedelics. Dr. Johnson also explains how the scientific study of psychedelics is likely to set the trajectory of psychiatric medicine in the years to come. Dr. Johnson is among a small handful of researchers who have pioneered the clinical study of these powerful compounds. He has unprecedented insight into how they can be woven into other psychiatric treatments, changing ones sense of self and of reality.   Thank you to our sponsors: Athletic Greens - http://www.athleticgreens.com/huberman Belcampo - http://www.belcampo.com/huberman InsideTracker - http://www.insidetracker.com/huberman   Dr. Matthew Johnson Social Media:  Twitter: https://twitter.com/drug_researcher  Instagram: https://instagram.com/drug_researcher    Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: http://www.thorne.com/u/huberman    Social: Instagram - https://www.instagram.com/hubermanlab  Twitter - https://twitter.com/hubermanlab  Facebook - https://www.facebook.com/hubermanlab  Website - https://hubermanlab.com  Newsletter - https://hubermanlab.com/neural-network    Links: Dr. Johnson’s Website at Johns Hopkins School of Medicine - https://hopkinspsychedelic.org/johnson Chris Letheby’s forthcoming book - https://amzn.to/3nMTaAs     Timestamps: 00:00:00 Introducing Dr. Matthew Johnson 00:02:10 Supporting Sponsors 00:06:40 ‘Psychedelics’ Defined 00:14:09 Hallucinations, Synesthesia, Altered Space-Time Perception 00:19:56 Serotonin & Dopamine  00:23:50 Ketamine & Glutamate  00:28:00 An Example Psychedelic Experiment 00:37:30 ‘Letting Go’ with Psychedelics 00:44:10 Our Mind’s Eye 00:48:00 Redefining Your Sense of Self  00:58:56 Exporting Psychedelic Learnings to Daily Life 01:04:36 Flashbacks 01:12:10 Ayahuasca, & ASMR, Kundalini Breathing 01:15:54 MDMA, DMT 01:26:00 Dangers of Psychedelics, Bad Trips, Long-Lasting Psychosis 01:38:15 Micro-Dosing 01:56:45 Risks for Kids, Adolescents & Teenagers; Future Clinical Trials 02:03:40 Legal Status: Decriminalization vs. Legalization vs. Regulation 02:18:35 Psychedelics for Treating Concussion & Traumatic Brain Injury  02:27:45 Shifting Trends in Psychedelic Research, Academic Culture 02:44:23 Participating in a Clinical Trial, Online Survey Studies, Breathwork  02:50:38 Conclusions, Subscribing & Supporting the HLP, Supplements Please note that The Huberman Lab Podcast is distinct from Dr. Huberman's teaching and research roles at Stanford University School of Medicine.
