I just wrapped up watching the 4 part Netflix series presented by Academy Award-winning filmmaker Alex Gibney and New York Times best-selling author Michael Pollan, How to Change Your Mind. I found this documentary to be a thorough look into the many benefits provided by 4 types of psychedelics, LSD, MDMA, psilocybin, and peyote (mescaline). It explores the suppression and criminalization of these substances, the many benefits of healing PTSD, depression, addiction, and the movement to decriminalize them.
