On July 8, 2013, officials from the U.S. Drug Enforcement Administration conducted a surprise audit of the drug accountability logs for our ongoing study of MDMA-assisted psychotherapy for U.S. veterans, firefighters, and police officers with service-related PTSD. The officials confirmed that all of the MDMA had been adequately tracked and labeled. According to Principal Investigator Michael Mithoefer, M.D., the officials were “friendly and helpful”they’re reasonable people and it feels like we have a good working relationship.” On July 5, the 14th subject received their first experimental MDMA-assisted psychotherapy session. This subject was enrolled on June 17.
