MDMA is a classical entactogen of the substituted amphetamine class, first developed in 1912 by the pharmaceutical company Merck. It remained largely obscure until the 1970s, when it gained recognition in underground psychotherapy circles before spreading into nightlife and rave culture. Now one of the most popular recreational drugs worldwide, it is known for producing strong feelings of empathy, emotional closeness, and stimulation. Tablets sold as "ecstasy" frequently contain adulterants or other substances entirely.
