Dimethoxyamphetamine

DMA, or dimethoxyamphetamine, is a series of lesser-known psychedelic drugs similar in structure to Amphetamine and to TMA (Trimethoxyamphetamine). They were first synthesized by Alexander Shulgin and written up in his book PIHKAL (Phenethylamines I Have Known and Loved). Very little data is known about their dangers or toxicity.

2,5-DMA

Note that two other positional isomers of dimethoxyamphetamine, 2,6-DMA and 3,5-DMA, have also been made, but these drugs have not been tested in humans and their effects are unknown. However it is likely that these compounds would also produce amphetamine-like stimulation or possibly hallucinogenic effects.
