Methylenedioxyamphetamine, also known as
3,4-methylenedioxy-amphetamine,
MDA,
tenamfetamine (
INN), or colloquially as "
Sally", "
Sass", or "
Sass-a-frass", is a psychoactive drug of the
substituted methylenedioxyphenethylamine and
substituted amphetamine classes of drugs that is consumed primarily for its
entactogenic,
psychedelic, and
psychostimulant effects. Pharmacologically, MDA acts as a serotonin-norepinephrine-dopamine
releasing agent and
reuptake inhibitor.
Possession of MDA is illegal in most countries. Some limited exceptions exist for scientific and medical research. The recreational use of MDA predates its more widely used analog
MDMA (ecstasy).
