How Different Psychedelics Compare

Dr. Grace Blest-Hopley is a neuroscientist and psychedelics researcher whose work is transforming how we understand trauma, addiction, and mental health. From cannabis and psychosis to MDMA and ibogaine, she sits at the frontier of how brain science meets healing.Grace has led research with the Heroic Hearts Project, helping veterans recover from PTSD through psychedelic therapy, and founded Hystelica, the world’s first research initiative focused on women’s health in psychedelic science. Her studies on cannabis, brain development, and the endocannabinoid system have influenced how clinicians, policymakers, and scientists think about drugs and the mind.Expect to learn how cannabis actually affects the developing brain, what the data really says about psychosis and THC, why CBD might protect against those effects, how psychedelics like MDMA and ibogaine are being used to treat trauma and addiction, the biological differences that make women’s brains respond differently to psychedelics, what the FDA’s recent MDMA rejection means for the future of mental health, why psychedelic therapy works on both the mind and the brain, and how this new neuroscience could redefine healing itself — and possibly the future of psychiatry.Subscribe to discover why your brain on drugs might not be what you think — and why the future of mental health may depend on rethinking everything we were told about them.Timestamps:00:00 Cannabis vs Alcohol: Which Is More Dangerous for the Brain?04:15 How Cannabis Affects the Teenage Brain and Memory08:10 Can Cannabis Trigger Psychosis?
