Jeeezus, keep it down
Some pretty sketchy evidence there. They make some big statements about the effects of ecstasy, then tell you they are talking about PMA - not MDMA. MDMA works by releasing all your brains stores of seratonin. Hence the come down the next day. Anecdotal evidence (dudes who have been doing it every 1-2 weeks for the last 20 years) suggest less long term effects than the media/government/police would have you believe.
