Dead Dog on the Left isn't just a documentary about the use of ecstasy in treating PTSD, it's a story of the lengths one former marine will go to for friendship. [Tyler] McCourry and [Nigel] Flanigan are the subjects of [the] mini-documentary taken from a forthcoming feature film, MDMA the Movie, which explores the history of the so-called "party drug" more popularly known as ecstasy, its use in therapy, and harm reduction. Both films are directed by Emanuel Sferios. His protagonists may have survived the Iraq war, but only barely. Suicidal thoughts have stalked them both. In May 2012 McCourry did his first [MDMA-assisted psychotherapy] session ... lying in bed, flanked by two therapists. At the beginning of the session he was given a 75mg dose of MDMA. "During those eight hours you're addressing the most challenging situations in your life," he says. "It feels very exhausting, like it was some of the most work you've ever done in one day." McCourry calls those trials, now completed, "a transformation of the psyche". MDMA-assisted psychotherapy has "breakthrough therapy" designation by the FDA. "Since the MDMA therapy I'm able to recognise when something comes up that I need to talk about," [McCourry] says. McCourry hopes that the therapy will be adopted by the Veterans Administration and Department of Defense. "If you can cure PTSD after three sessions of MDMA therapy then you don't have to provide a veteran with medications for the rest of their life and talk therapy once a month."
