I’m not sure, but I think they’re the same, but I did ecstasy about 10 times when I was 19 and it burned me out and I never did it again. That’s been about 23 years or so now, maybe it’s different now it if it works the same I’d imagine it’s still a serotonin drain.
They say Ecstacy does not equal MDMA due to much of it being adulterated with other drugs. But Ecstacy is
supposed to be MDMA, that's what it's sold as. My brother showed me a baggie of MDMA and it was this pink colored powder. The brain damage evidence is bit conflicting and the advice of doing it "just X amount of times per year" is not scientific, just an attempt to reduce exposure. But I would definitely err on the side of caution. Some say ADHD amphetamines cause brain damage, based on meth addict data, but it's still not known if low doses of say
20mg a day do it. The addicts may take the equivalent of a gram or more per dday. My buddy who stopped using injectable speed 30 or 40 years ago says "half a gram of speed IV cures everything." He still reminisces romantically those days but knows if he were to do it again his life would go to hell immediately.
I know "molly" is referenced in pop music all the time still, especially rap. That along with the "purple drank" or "Lean," cough medicine mixed with 7up.
