Using ecstasy, known scientifically as methylenedioxymethamphetamine (MDMA), to assist psychotherapy could be a viable treatment for post-traumatic stress disorder (PTSD), according to research published today in the respectable Journal of Psychopharmacology. PTSD is a debilitating and often chronic condition characterized by anxiety, hypervigilance and intrusive recollection of traumatic memories, including nightmares and flashbacks.
