MMDA-3a, also known as 2-methoxy-3,4-methylenedioxyamphetamine or as 2-methoxy-MDA, is a psychedelic drug of the amphetamine family. It is the 2-methoxy derivative of 3,4-methylenedioxyamphetamine (MDA). The drug produces hallucinogenic effects in humans. Its dosage is listed as 20 to 80 mg and its duration as 10 to 16 hours in PiHKAL. A higher dose of 100 mg was also reportedly explored and doses of 80 to 100 mg were said to be very similar to 100 μg LSD. MMDA-3a is a positional isomer of MMDA and hence is a Schedule I controlled substance in the United States.
