DMA, or dimethoxyamphetamine, is a series of lesser-known psychedelic drugs similar in structure to amphetamine and to trimethoxyamphetamine (TMA). They were first synthesized by Alexander Shulgin and written up in his book PiHKAL (Phenethylamines I Have Known And Loved).[1] Very little data is known about their dangers or toxicity.

Positional isomers


2,4-DMA, or 2,4-dimethoxy-amphetamine

Dosage: 60 mg or greater

Duration: short

Effects: stimulative, amphetamine-like effects


2,5-DMA, or 2,5-dimethoxy-amphetamine

The DO analogue of 2C-H (DOH)

CAS Number: 2801-68-5

Dosage: 80–160 mg[2]

Duration: 6–8 hours

Effects: Mydriasis, increase in heart rate


3,4-DMA, or 3,4-dimethoxy-amphetamine

Dosage: unknown

Duration: unknown

Effects: Mescaline-like visuals

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.
