I've taken MDMA in capsules before and had my eyes rolling in the back of my head and passing out and sweating before, and know for a fact it was MDMA... I don't think that stuff has much bearing on the situation, actually... most good MDMA will do that to you :D
I think what I am getting at, is that 90% of MDMA related deaths might not be that at all, but just because of that we shouldn't automatically assume it's not true when someone dies. I think that more information needs to be gathered, but Noone should say otherwise until there is proof either way. I think we all know the validity of most MDMA related deaths is next to none, but thats still not 100% and even a small chance of dying is enough chance that people should be warned against MDMA period.
This is a harm reduction site, NEVER taking anything is always the safest way--if you ARE going to take MDMA no matter what, then there are several resources(heh, prolly not the MDMA forum here--damn pillheads) that provide plenty of helpful information as to how to minimize any risk. In any event, I am sure we can all agree that this is a terrible situation, regardless.
