Join us as we dive back into the world of psychedelic medicine with anesthesiologists Boris Heifets and Theresa Lii, who share intriguing new data that sheds light on how ketamine and placebo effects may interact in treating depression.We explore provocative questions like: How much of ketamine's antidepressant effect comes from the drug itself versus the excitement of being in a psychedelics trial? What do we know about how placebo actually works in the brain? And should we view the placebo effect as a feature rather than a bug in psychiatric treatment?Join us as we examine the complex interplay between psychoactive drugs, the brain's own opioid system, and the healing power of hope in mental health care.Related researchPreprint: Opioids Diminish the Placebo Antidepressant Response: A Post Hoc Analysis of a Randomized Controlled Ketamine Trial (medRxiv, 2024)Randomized trial of ketamine masked by surgical anesthesia in patients with depression (Nature Mental Health, 2023)Related episodesPsychedelics, placebo, and anesthetic dreams | Boris Heifets (Part 1) Psychedelics Inside Out: How do LSD and psilocybin alter perception? | Boris Heifets (Part 2)OCD and Ketamine | Carolyn RodriguezPsychedelics and Empathy: Why are psychiatrists taking a fresh look at MDMA? | Rob MalenkaRelated newsResearchers find response to ketamine depends on opioid pathways, but varies by sex (Stanford Medicine, 2024)The rebirth of psychedelic medicine (Wu Tsai Neuro, 2023)Can Psychedelic Drugs Treat Physical Pain?
