MDMA in its pure form is no more dangerous that taking bath if done in a responsible way.
MDMA was used in couples therapy and worked extremely well but soon as kids started doing it in clubs the government banded its use. Now people cut MDMA with other shit making the party drug ecstasy that can be dangerous. If you do a drug or take a bath make sure you know what your getting into. You wont have someone draw a bath, and then jump right in with out asking how cold/hot the water is will you?
MDMA might also be a wonder drug for helping people with PTSD. It has helped a good amount of people so far coming back from war and its crazy to think that it might help save ALOT of lives. Suicide is a big problem in the military and if this helps even 25% of people then that is a big win.
Do drugs.
