MMDA-2 (2-methoxy-4,5-methylenedioxyamphetamine) is a psychedelic drug of the amphetamine class.[1] It is closely related to MMDA and MDA.[1]

Alexander Shulgin was likely the first to synthesize MMDA-2.[1] In his book PiHKAL, the dose is listed as 25–50 mg, and the duration is listed as 8–12 hours.[1] Shulgin reports that MMDA-2 produces effects such as enhanced awareness, empathy, and visual facilitation and distortion, as well as some side effects like gastrointestinal upset and appetite loss.[1] He states that 30 mg is very similar to 80 mg of MDA, and also remarks that it would be impossible for anyone to have a bad experience on the drug at that dose.[1]

Scientific research has shown that MMDA-2, unlike MMDA, but similarly to 6-methyl-MDA, is only very weak at inducing the release of serotonin or dopamine,[2] and accordingly, does not produce amphetamine-like responses in animals in drug discrimination studies.[3] Instead, MMDA-2 is likely to act as a pure 5-HT2 receptor agonist similarly to the DOx series of compounds, with activation of the 5-HT2A receptor conferring its psychedelic effects.[4]

MMDA-2 has been sold as a designer drug in Japan.[5]
