Considering that this is coming from the same drug culture that uses the word "molly" refer to "some mixture of empatheogenic drugs and possibly some amphetamine", expecting specificity from your terminology is a bit unrealistic.

I'm not (just) being judgmental here: volunteering harm reduction at festivals, the number 1 problem we had was that users had no idea what they had put into their bodies.

Actual chemists, no doubt, don't use any of this terminology since chemical reactions don't produce the desired results if you're vague about what you put into them.
