Empathogen-entactogen

The terms empathogen and entactogen are used to designate a class of psychoactive drugs that produce experiences of emotional communion, oneness, relatedness, emotional openness—that is, empathy or sympathy—as particularly observed and reported for experiences with MDMA (ecstasy). This class of drug is distinguished from the classes of hallucinogen or psychedelic, and amphetamine or stimulant. Major members of this class include MDMA, MDA, MDEA, MDOH, MBDB, 6-APB, methylone, mephedrone, αMT, and αET, among others. Most entactogens are phenethylamines and amphetamines, although several, such as αMT and αET, are tryptamines. When referring to MDMA and its counterparts, the term 'MDxx' is often used (with the exception of MDPV). Entactogens are sometimes incorrectly referred to as hallucinogens or stimulants, although many entactogens exhibit psychedelic and/or stimulant properties as well.
