I agree with the sentiment, but I don't think the "mongy" MDMA has anything to do with longterm comedowns. Myself and many others I know have had experiences with MehDMA and while it isn't that great, its not necessarily bad either and doesn't give any more or less hangover/comedown than the good stuff. I've had "Molly" that was god knows what, as in 100% not MDxx period, and that stuff makes the MehDMA seem like a godsend. I don't believe its dangerous or anything, its just a shadow of what the true experience can and should be. Unless of course the MehDMA we've got ahold of is not the same that you're talking about (but we'll find out around this coming Wednesday).
Every story that I read on here of people with LTC, either they did WAY too MDMA (too often, redosing, massive doses, or all of the above), were also combing other drugs, maybe had some pre existing condition, or a combination of all those factors. Nobody has come on here saying they took 100mg of tested MDMA and now they're struggling with a LTC 9 months later. Even back in 90's when it was all good, there has got to be tons of people who did/still do have serious problems from doing way too much MDMA (not to mention an even less amount of information on the stuff), they just didn't have the internet communities we do now to share their stories and ask for help.
I wish they'd reply too, but as someone who didn't really believe til I felt it with my own body and mind, it really does seem like a bunch of burnt out ravers in here, especially early on (which is why I'd love for this discussion to transition into "What's wrong with some batches of MDMA", it negates that knee jerk response).
Hell, if we want to be taken seriously we should probably drop the term "mongy", which comes from a racist term used to describe someone with mental disability.
