3,4,5-Trimethoxyamphetamine (TMA, TMA-1, or 3,4,5-TMA), also known as α-methylmescaline or mescalamphetamine, is a psychedelic drug of the phenethylamine and amphetamine families. It is one of the trimethoxyamphetamine (TMA) series of positional isomers. The drug is notable in being the amphetamine (i.e., α-methylated) analogue of mescaline (3,4,5-trimethoxyphenethylamine).
