    MMDA structure

    Summary

    MMDA is a stimulant. Reported effects include euphoria, color enhancement, time distortion, and wakefulness. Limited data is available on its dosage and safety profile.

    Perspectives

    “I felt completely relaxed at one hour. Almost as if I was floating. There were no obvious effects on taste, and the relaxation and composed feeling is much like a small dose, maybe 20 mikes, of LSD. There was some dilation, and in the evening I was a little restless and slightly tired. I slept well, and awoke refreshed and happy.”
