Your replies where you implied that anyone who drinks alcohol or takes a medically approved medicine tests it before use, and descended into incoherent rambling and ad-hominems when challenged..?

Already read them, thanks; didn't see any convincing arguments.

No such thing as responsible recreational drug use (and that includes alcohol, tobacco, caffeine, and any other legal addictive drug, including medicines except under the supervision of a doctor).

You're not special. If you use addictive drugs your risk of getting addicted is the same as anyone else's, no matter how “responsible” you are. Chemistry is not subjective.

And in most cases (especially in the case of alcohol and tobacco, but also with most other recreational drugs that affect brain function or produce toxic fumes) you'll eventually become a danger to yourself and probably others. That's literally the opposite of being responsible.
