so i wanted to work on that with annie mithoefer. >> rachel says she saw almost instant improvement after the mdma assisted therapy. although it's key to remember she, as well as all the test patients, did undergo extensive post sessions to process the emotions the mdma dug up. >> it's not just what happened during the mdma effect... the process, it's an experience that continues to unfold so it's important to have proper support to help people integrate and to continue to benefit from the experience. >> in july 2010, doctor mithoefer published the findings from this first phase of his study in the journal of psychopharmacology. a positive clinical response occurred in 83 percent of those patients given mdma. that's in comparison to the 25 percent found in placebo patients. >> so, we often have this sense "well maybe a couple of years worth of therapy just happened today". so there is something about the mdma that seems to help a lot happen in a short period of time. >> today rachel insists she has completely recovered from ptsd and is living a healthy life, with no long term side effects
