Paramethoxyamphetamine (PMA) and paramethoxymethamphetamine (PMMA) are stimulants with hallucinogenic effects similar to MDMA, which is the main ingredient in ecstasy. In fact most people who take PMA or PMMA think they are taking ecstasy. However, drugs sold as ecstasy may not contain any MDMA. They can be a mix of amphetamines, PMA, PMMA, ketamine, NBOMe, methylone or other substances. This is potentially harmful as PMA and PMMA have more toxic effects (and are less euphoric) than MDMA. It also takes longer to feel these effects, so people may take another pill in the mistaken belief that the first has not worked, sometimes resulting in overdose.
