ecstasy is one of the more potent drugs known to man - people die on it cause they can't tell if they are thirsty or not or something - then woops one too many 2 liters down the hatch.
It also according to what I've heard messes up your brain chemistry pretty bad even the first time you try it.
It does some crap with your seratonin which is the chemical in your brain that makes you feel good. So you can end up like not producing it or something as a result and then you basically need extacy to be happy.
I'm really rusty on this sh*t but extacy/mdma/x will really mess you up.
