I still don't think that is really sufficient evidence, like said above most MD studies involve stupidly high doses repeatedly injected. if there was CONCRETE evidence of MDMA induced lesions, a lot more people would be taking about it. Hell, Olneys lesions are not even that well known about and I've never even done dissociatives but I've heard of those before this. I think with sufficient antioxidants, a good diet, a little 5-htp replenishment and a 1-3 month break each time, MDMA will cause little worry. The neurotoxicity of it is so debated that it's obvious now that with precaution it's really not that bad, or it would have a much worse reputation than it does (look at meth for example)
