3-Methoxy-4-methylamphetamine

Not to be confused with meta-Methoxyamphetamine.

3-Methoxy-4-methylamphetamine (MMA) is an entactogen and psychedelic drug of the phenethylamine and amphetamine classes.^[1][2] It was first synthesized in 1970^[1] and was encountered as a street drug in Italy in the same decade.^[3] MMA was largely forgotten until being reassayed by David E. Nichols as a non-neurotoxic MDMA analogue in 1991,^[2] and has subsequently been sold as a designer drug on the internet since the late 2000s.^{[citation needed]}

In animal studies, MMA fully substitutes for MDMA and MBDB, partially substitutes for LSD, and does not substitute for amphetamine.^[2] Additionally, it has been shown to be a potent and highly selective serotonin releasing agent (SSRA) and does not produce serotonergic neurotoxicity in rodents.^[4][2][5] These data appear to confer a profile of MMA as a selective serotonin releasing agent (SSRA) and serotonin 5-HT_2A receptor agonist.^[2]

In humans, MMA has been reported to be hallucinogenic, "quite dypshoric", and long-lasting.^[6] The active doses have been reported to be 40 to 60 mg.^[6] Capsules containing 140 mg have been encountered as a designer drug in Italy in the 1980s.^[6]

The 2-aminoindane analogue of MMA is 5-methoxy-6-methyl-2-aminoindane (MMAI).^[7][5]
