MDMA
     n : a stimulant drug that is chemically related to mescaline and
         amphetamine and is used illicitly for its euphoric and
         hallucinogenic effects; it was formerly used in
         psychotherapy but in 1985 it was declared illegal in the
         United States; "MDMA is often used at parties because it
         enables party-goers to remain active for long periods of
         time" [syn: {methylenedioxymethamphetamine}]
