The article below is from the Belgian Drugs early warning system. It confirms (without excessive scaremongering too) that the MDMA pills are twice as strong as those of 10 years ago (in 2006/7 there was actually a rise in pill quality in Europe) and warns against both excessive use and combination of alcohol, also pointing out quite correctly that comedowns and medium term health issues can get way worse overdoing it (rather than simply the risk of just dropping dead)
