 | | ABSTRACT: Analysis of a set of mixed-component Ecstasy tablets by GC/MS indicated an apparent mixture of 3,4-methylenedioxymethamphetamine (MDMA) and 3,4-methylendioxyamphetamine (MDA); however, the mass spectrum for the MDA did not exactly match an MDA standard. |
 | | Over the past few years, so-called "Ecstasy" tablets have undergone a dramatic transition in their composition.Five years ago, most Ecstasy tablets contained either 3,4-methylenedioxymethamphetamine (MDMA), 3,4-methylenedioxyamphetamine (MDA), or (less commonly), a mixture of MDMA and MDA. |
 | | More recently, however, Ecstasy tablets have often contained complex mixtures of controlled substances, control substance analogues, alternate abused substances, adulterants, diluents, and manufacturing impurities and byproducts. |
