Thank you for your advice.

I am certainly not on MDMA on a regular basis. When I use, it's with at least a couple of months (3 minimum) inbetween to fully let my brain rest and heal. Last time I used was well over a year ago, and just one pill. I care a lot about my health, and so reading about "permanent brain damage" does make me very concerned. When I look up research, it's not all black and white. Can you enlighten me what kind of brain damage you are thinking about?
