After returning home from the Vietnam War, Bob realized he was not the same person as before, and eventually became aware of his PTSD after years of struggle. After reading Michael Pollan’s book “How To Change Your Mind,” he immediately began exploring psychedelic therapy as an option to heal his trauma. Parsons is currently working with MAPS to help conduct clinical trials of MDMA-assisted therapy for FDA approval, and with Dr. Rachel Yehuda to help with PTSD research, and to train therapists to specialize in treating veterans and active-duty members with psychedelics.
