||No. MDMA was investigated by US Army Intelligence during the early 1950's as part of a wide ranging study of psychoactive drugs conducted at the Edgewood Arsenal in Maryland. It was assigned the code name EA-1475 and some preliminary animal experiments were performed, but it was never used on human test subjects and was soon abandoned.|
It was not until the mid to late 60's that the first reports of human use started to filter out. These were not in a clinical setting, but rather personal experimentation by individuals. Check out the MDMA timeline for more details about the history of MDMA.
