Methyl-TMA, or N-methyl-TMA, also known as N-methyl-3,4,5-trimethoxyamphetamine, is a psychedelic drug of the phenethylamine, amphetamine, and 3C families. It is the N-methyl derivative of 3,4,5-trimethoxyamphetamine (TMA) as well as the α,N-dimethyl derivative of mescaline (3,4,5-trimethoxyphenethylamine).
Use and effects N-Methylation of psychedelic phenethylamines has invariably greatly reduced or eliminated their hallucinogenic activity. Examples of this include related compounds like Beatrice (N-methyl-DOM) and methyl-DOB (N-methyl-DOB), which at assessed doses appear to be inactive as psychedelics in humans. According to Alexander Shulgin in his book PiHKAL (Phenethylamines I Have Known and Loved) however, methyl-TMA showed "some mental disturbances" at the highest assessed dose of 240 mg orally. For comparison, the active dose range of TMA is 100 to 250 mg orally.
Interactions
History Methyl-TMA was first described in the scientific literature by at least 1984. It was subsequently described further by Shulgin in PiHKAL in 1991.
