It's true that the A in MDMA stands for amphetamine as noted below, but saying that people who use MDMA like amphetamines is like saying that people who use table salt like chlorine. It's the best kind of correct, but misleading.
Clean MDMA is increasingly hard to come by. If you have a good plug, consider yourself lucky. But in the year of our lord 2025, almost all crystalline or powder recreational compounds have been stepped on to an absurd degree.
