Summary
TMA is a rare synthetic psychedelic amphetamine and the alpha-methylated analog of mescaline. Effects are generally less visual and less euphoric than mescaline, with more unpredictable emotional responses. At higher doses (above 200 mg), Shulgin's research documented potentially antisocial behavioral changes including anger and hostility, which were not observed with mescaline. Effects include mild psychedelic aura, tactile enhancement, and dreamy mental states with minimal visuals at lower doses. There is extremely limited human use history and virtually no modern research.
Perspectives
“I had no nausea, although I always vomit with mescaline. Somehow my personality was divided and exposed, and this allowed me to understand my psychic structure more clearly. But maybe others could look in there, too. The psychiatric use of this drug would be interesting to pursue. It is not completely pleasant, maybe because of this personal intimacy.”
“TMA provided an interesting and insightful low-level psychedelic experience with manageable but noticeable bodyload.”
