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
Hallucinogenic fish that makes dreams" in Arabic. Other species claimed to be capable of producing hallucinations include several species of sea chub from the genus "Kyphosus". It is unclear whether the toxins are produced by the fish themselves or by marine algae in their diet. Other hallucinogenic fish are "Siganus spinus", called "the fish that inebriates" in Reunion Island, and "Mulloidichthys flavolineatus" (formerly "Mulloidichthys samoensis"), called "the chief of ghosts" in Hawaii. The active agent(s) that cause hallucinations in humans, and the origin of these agents, are not clear. Some authors think they could come from toxins associated with macroalgae that accumulate
