Any drug is dangerous if you are an idiot and dont know how to control yourself and your body.
MDMA is not dangerous - drinking not enough or too much water is, but if our sensible then the chances of anything going wrong are pretty non existent
we're not talking about how anything can be dangerous here, we're talking about its likely hood of being dangerous. You are much more likely to die of an E overdose and get brain damage from E then too much fuckin water.
