I feel there is a fair bit of scaremongering on this thread...
From personal experience, I have used MDMA in doses ranging from 200 - 500mg, and whilst the latter dosage left me feeling pretty shit for a week of two afterwards (brain zaps etc...not to be repeated), I made a full recovery a short while after. My message is this - just fucking
enjoy yourself. Don't sit there wigging out about how MDMA may or may not be neurotoxic, just enjoy it and don't take liberties. I would say that MDMA is one of the safest drugs you can do, and I have never once felt in danger or permanently brain damaged on any dose. People complaining of "nerve damage" and "8 month long comedowns" are either giving themselves psychosomatic symptoms caused by an anxiety loop, or didn't get MDMA to begin with...(more likely the former).
The amount of scaremongering in ED is sometimes absurd
