On March 24, 2015, the fourth subject was treated in our ongoing Canadian study of MDMA-assisted psychotherapy for PTSD. This subject was enrolled on March 6, and treated by co-therapists Donna Dryer, M.D., and Richard Yensen, Ph.D. Led by Principal Investigator Ingrid Pacey, M.D., in Vancouver, B.C., this Phase 2 study will treat up to 12 subjects with chronic, treatment-resistant PTSD from sexual assault, violent crime, military service, or any other cause. This is the first Health Canada-approved clinical psychedelic research to take place in over 40 years. "As we prepare for the next set of four experimental psychotherapy sessions, we are honored and humbled to be working with such courageous subjects," writes co-therapist Dr. Dryer.
