Dr. Robin Carhart-Harris is a distinguished professor of neurology and psychiatry at the University of California, San Francisco, and one of the foremost experts on the interplay of neuroscience and psychedelics. He studies how psychedelics such as psilocybin, LSD and DMT can change the human brain and be used to treat various mental health challenges such as trauma disorders, major depression, obsessive-compulsive disorder (OCD), and addiction. Dr. Carhart-Harris joined Rep. Crenshaw to discuss the latest findings from clinical trials of psychedelic therapies, how the mind is affected by the different kinds of psychedelics, the legal landscape for these therapies, and the risks and benefits he sees in psychedelics, other prescription drugs, and alcohol.
