3,4-Methylenedioxyamphetamine (also known as MDA and sass) is an empathogen-entactogen, psychostimulant, and psychedelic drug of the amphetamine family that is encountered mainly as a recreational drug. In its pharmacology, MDA is a serotonin–norepinephrine–dopamine releasing agent (SNDRA).
MDMA, also called Molly or Ecstasy, is a lab-made (synthetic) drug that has effects similar to stimulants like methamphetamine, although some researchers and organizations consider MDMA to be a psychedelic drug because it can also mildly alter visual and time perception.
