MDA is a synthetic entactogen of the amphetamine class that produces stimulant and mild psychedelic effects alongside its empathogenic properties. First synthesized in 1910, its psychoactive effects were not recognized until 1930, and it emerged as a recreational substance in the late 1960s, predating the popularization of its close relative MDMA. Compared to MDMA, MDA is generally considered more stimulating with a stronger psychedelic edge. It is sometimes found in pills sold as MDMA, and vice versa.
