3-Chloromethamphetamine (3-CMA, MCMA) is a substituted amphetamine derivative invented in the 1960s. In animal studies it was deemed to be a "hallucinogen" rather than a stimulant, though the assays used at the time did not distinguish between the compounds now termed psychedelics and those now termed empathogens.
