> XTC usually refers to MDMA in pill form, used to be contaminated/mixed with some other additives but it's largely MDMA these days.

Ecstasy is almost never pure. While the degree of contamination varies and may not be subjectively noticeable by the user, the vast majority of ecstasy has some degree of adulterants in it, often other amphetamines, and sometimes other substances altogether.
