    Summary PsychonautWiki

    3,4-Methylenedioxyamphetamine (also known as MDA, and Tenamfetamine, or colloquially as "Sally", "Sass", or "Sass-a-frass") is a synthetic entactogen of the amphetamine chemical class. It produces long-lived entactogenic, stimulant and mild psychedelic effects that include stimulation, anxiety suppression, enhanced feelings of empathy, affection, and sociability, and euphoria when administered.

    Perspectives

    “The coming on was gradual and pleasant, taking from an hour to an hour and one half to do so. The trip was euphoric and intense despite my having been naturally depleted from a working day and having started so late. One thing that impressed itself upon me was the feeling I got of seeing the play of events, of what I thought to be the significance of certain people coming into my life, and why my ‘dance’, like everyone else’s, is unique. I saw that every encounter or event is a potential for growth, and an opportunity for me to realize my completeness at where I am, here and now, not at some future where I must lug the pieces of the past for a final assemblage ‘there.’ I was reminded of living the moment to its fullest and I felt that seeing this was indicative that I was on the right track.”

    “Make no mistake about it, this was a strong roll. 80mg came on fast and whisked me away with a head and body high that took me to the edge. Caution should be exercised both with dose and frequency of use.”

    Tolerance

    No tolerance chart. No study has measured how long tolerance to it lasts, so this page shows what is known instead of a curve.

    No study has measured tolerance to MDA: the two controlled human studies each gave a single dose, and none has tested repeat doses. PsychonautWiki estimates that tolerance halves in about 3 days and is gone in about 7, without citing a source. What is known about repeat MDMA doses has not been tested for MDA.

    Effects Erowid Bluelight

    Aggregated from 56 single-substance Erowid and 53 Bluelight experience reports (the Bluelight figures come from the 50 of them read for effects); 63 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.

    Also reported in combinations. In the 63 MDA reports where another drug was taken too, 3 (4.8%) mention hospital, emergency services or an overdose, 0 (0.0%) a seizure and 2 (3.2%) psychosis. In the 56 single-substance reports: 3.6%, 0.0% and 3.6%. These are not in the figures above: they cannot be put down to MDA alone, and a mention is not always something that happened to the writer.

The trip was euphoric and intense despite my having been naturally depleted from a working day and having started so late. One thing that impressed itself upon me was the feeling I got of seeing the play of events, of what I thought to be the significance of certain people coming into my life, and why my ‘dance’, like everyone else’s, is unique. I saw that every encounter or event is a potential for growth, and an opportunity for me to realize my completeness at where I am, here and now, not at some future where I must lug the pieces of the past for a final assemblage ‘there.’ I was reminded of living the moment to its fullest and I felt that seeing this was indicative that I was on the right track.”
