PMA, or paramethoxyamphetamine, is a synthetic hallucinogen that is often sold as Ecstasy. It is a stimulant with hallucinogenic effects similar to MDMA, but it is more poisonous and can kill at lower doses than MDMA. PMA and PMMA (paramethoxymethamphetamine) are empathogens with effects similar to MDMA. PMA is usually swallowed, but it can also be snorted or injected. It affects the bodys temperature control, and the risk of overheating may be greater than ecstasy, as it is more poisonous. PMA can cause cardiac arrhythmia, breathing problems, pulmonary congestion, kidney failure, hypothermia, vomiting, convulsions, coma, and death. The long-term effects of PMA are unknown. Signs of use include erratic eye movements, muscle spasms, nausea, and heightened visual stimulation. PMA is a Schedule I drug under the Convention on Psychotropic Substances and is considered a Schedule 9 prohibited substance in Australia under the Poisons Standard.
