Thanks for your reply. I knew it was only a matter of time before the demand for evidence was trotted out. As far as evidence demands go, it's certainly a fair request. One of the challenges with MDMA usage is that there is relatively little published research on the subject, so a general attitude of "prove it otherwise" exists which can be completely independent of the reality on the ground, for or against.
For anecdotal evidence I refer you to Anne Shulgin's experience with regular MDMA use, bluelight.ru, erowoid.org and dancesafe.org. Anecdotal evidence tells us nothing in concrete terms, so I will be researching and in short order posting the literature I have run across that supports that frequent and high dose MDMA usage leads to the set or subset of the phenomenon that is commonly termed "loss of magic". Conservatively speaking, perhaps only people who experience problems with MDMA frequent these websites with those who have no problems never frequenting them is a plausible yet unlikely possibility, so in a world where we must error on the side of conservatism I cede that point to you.
By the way, I think you are completely on track with the statements that eventually and regularly are relative terms. I took MDMA regularly for 10 years before I eventually burned out. What constitutes regularly and eventually are completely subjective to the individual. It would be just as fool hardy for me to say that every individual who uses MDMA on the same basis I did would reach the same conclusion at the same length of time, just as it would be equally foolish to assert that every individual who uses MDMA on your weekly frequency for indefinite periods of time would suffer no ill effects.
I awish for studies that demonstrate, on average, a person can use MDMA weekly for indefinite lengths of time with no deleterious effects experienced as loss of magic. In that case I would become an unfortunate outlier in the data set. In the absence of that evidence we must go on concensus and subjective experience which is that people report a diminishment in the experience and a loss of magic with long-term use, especially abuse - relatively speaking. We both know, or at least I know, what common experiential consensus on safe MDMA usage is at this time.
For what it's worth - I want you to be right. In my perfect world - the majority of MDMA users can use MDMA on a weekly (or daily) basis for an indefinite period, be that decades or score of years, and never suffer any subjective deleterious effects, regardless of real or imagined loss of magic. It would suck for me and anyone else who found that regular, long-term use (relatively speaking) leads to loss of magic to be the exception to the rule, but it would be a great stride for MDMA. Unfortunately, I don't see that message born out in anecdotal experience or both literature for or against MDMA (not to be confused with studies that show MDMA causes no long-term damage).
