Trimethoxyamphetamine Trimethoxyamphetamine TMAs, also known as trimethoxyamphetamines, are a family of isomeric psychedelic hallucinogenic drugs. There exist six different TMAs that differ only in the position of the three methoxy groups: TMA, TMA-2, TMA-3, TMA-4, TMA-5, and TMA-6. The TMAs are analogs of the phenethylamine cactus alkaloid mescaline. The TMAs are substituted amphetamines, however, their action does not resemble that of the unsubstituted compound "amphetamine", which is a stimulant and not a psychedelic. It is reported that some TMA's elicit a range of emotions ranging from sadness to empathy and euphoria. TMA was first synthesized by Hey, in 1947. Synthesis data
