dying from use of ecstasy increases significantly when a batch of ecstasy pills containing PMA starts to be sold in a particular area. PMA pills could be a variety of colours or imprints, and there is no way of knowing just from the appearance of a pill what drug(s) it might contain. Notable batches of pills containing PMA have included Louis Vuitton, Mitsubishi Turbo, Blue Transformers, Red/Blue Mitsubishi and Yellow Euro pills. Also PMA has been found in powder form. Analogues Four analogues of PMA have been reported to be sold on the black market, including PMMA, PMEA, 4-ETA and 4-MTA. These are the N-methyl, N-ethyl, 4-ethoxy and 4-methylthio analogues of PMA, respectively. PMMA and PMEA are anecdotally weaker, more "ecstasy-like" and somewhat less dangerous than PMA itself, but can still produce nausea and hyperthermia similar to that produced by PMA, albeit at slightly higher doses. 4-EtOA was briefly sold in Canada in the 1970s, but little is known about it. 4-MTA, however, is even more dangerous than PMA and produces strong serotonergic effects and intense hyperthermia, but with little to no euphoria, and was implicated in several deaths in the late 1990s.
