MDMA is the scientific name for ecstasy, which also goes by the street name Molly. The compound was synthesized by Merck in the early 1900s, but it never reached the market. Eventually, the compound was synthesized in a local home in San Francisco. MDMA exerts a wide variety of empathogenic qualities. The drug has been listed as a Schedule One substance in the United States for many years, indicating that it has a high potential for abuse; however, recent research indicates that the drug could have potential therapeutic benefits in the treatment of PTSD. The FDA labeled MDMA as a breakthrough treatment option in the treatment of PTSD, spurring further research into the compound. Individuals who take MDMA often report feelings of increased energy, changes in sensation, and feelings of pleasure. The effects usually start in approximately 30 minutes, and they tend to dissipate in approximately six hours.
