An empathogen commonly used in place of MDMA, having a similar duration of empathogenic effects. This drug, however, has a longer stimulant "tail," during which effects are more like those of amphetamines. Not to be confused with 4-FMA, which has a similar potency, but is not particularly empathogenic.
