Psychedelics for Treating Mental Disorders | Dr. Matthew Johnson
About this video
Dr. Matthew Johnson, a professor of psychiatry at Johns Hopkins who directs its Center for Psychedelic and Consciousness Research, walks Huberman through research on psychedelics such as psilocybin and LSD for treating depression, trauma, and other mental disorders. Dr. Johnson discusses microdosing and more typical macrodosing, and describes what a laboratory session treating depression looks like from start to finish. In the slices, the pair discuss MDMA: Huberman notes his understanding that MDMA robustly increases both dopamine and serotonin, and Dr. Johnson speculates that reduced amygdala reactivity may help people reprocess memories differently. Dr. Johnson suggests MDMA may carry a lower chance of an extremely challenging experience than classic psychedelics, while stressing that which compound suits which condition is not yet known. Dr. Johnson also emphasizes that he never encourages people to take drugs, noting every drug has its risk.
