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.”

— Alexander Shulgin, PiHKAL (with 100 mg)

Effects Erowid

Aggregated from 4 single-substance Erowid experience reports; 1 Erowid reports where another drug was taken too are left out

Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.

Too few reports for bars: these effects come from 4 single-substance Erowid reports, and a bar is drawn only from 20 reports or more. With fewer, a percentage cannot tell a common effect from a rare one. Counts are shown instead. Why 20?

Like Swimming in a Warm Ocean Full of Love positive exp #117164

I was very interested in trying MMDA after reading a few of the scarce trip reports online and Shulgin's reports. Easygoing euphoria with intense "mind movie" CEVs sounded incredible.

A Compound I Had Long Been Interested In positive exp #115680

MMDA: A Thorough Review and Bioassay of The Et [title truncated?] This had been a compound I had long been interested in, having read about Shulgin's experiences with "mind movies" and, more specifically, Claudio Naranjo's description of MMDA as a very useful therapeutic agent.

There Was Life In Those Eyes positive exp #98992

June 4th, 2010 3-methoxy-4,5-methylendioxyamphetamine Dosage: 195mg Prologue: MMDA looks appealing just based on structure alone. If one drew the structure of mescaline, then superimposed the structure of MDA over mescaline you would get MMDA. Or, you could look at it as 3-MeO-MDA.

Miniature High cautionary exp #92427

I use the word miniature in the sense that I would describe a piece by the jazz pianist Bud Powell as a miniature. Comparing a Beethoven piano sonata with 'Autumn in New York' as played by Powell would be analogous to comparing mescaline and MMDA.

Observations on Psychoactive Effects of MMDA positive exp #92426
