I've met and talked to 3 people with PhD. that are working with drugs like MDMA and all of them told me that for mehDMA vs. MagicDMA is no evidence.
There have been links posted here to multiple research studies that demonstrate a quantifiable difference in MDMA samples due to contaminants, despite appearing to be MDMA on commonly available tests (GCMS). Although these studies present the lab side of the conversation, they lack the user experience piece.
From the article you posted, "MDMA acutely induces feelings of well-being, love, empathy, and prosociality [
14,
15], and produces mild perceptual alterations that are thought to be primarily mediated by the release of serotonin (5-HT) [
16,
17] and norepinephrine [
18], and the direct activation of 5-HT2A receptors [
19]."
What we have been discussing here is that some lab tested "MDMA" does not produce "feelings of well-being, love, empathy, and prosociality."
I also noted in the link that you posted that, "Preferred recreational doses are slightly lower and in the range of 80–120 mg" and that a 125 mg dose should produce "the full range of empathogenic MDMA-typical effects." From the user reports posted to this thread, "meh-DMA" is not fully active at 80-120 mg, with some users reporting substandard effects at doses up to 155 mg.
So, if research demonstrates that those are the effects/dose of MDMA, but MDMA is not producing the documented effects (across multiple users), then "what is wrong the MDMA?"
Now, admittedly, perhaps a better question is "What is wrong with the testing of MDMA?" as it is seeming more and more clear that testing methodologies are missing contaminants and/or impostor substances.
In any case, thanks for posting the link. I will read it more closely and go over the scale. Perhaps posters to this thread can begin to use the scale to share user reports.
