So can plenty of prescription drugs. I suspect you wouldn't criticize someone for suggesting, "unwarranted", that someone tries anti-depressants or any number of potentially dangerous anxiolytics.
I would absolutely give them flak because you are exactly right about these drugs. If certain medications/"medications" can help people in any way, that's awesome! But we can't treat them like harmless fun candy or like a productivity/meditation hack.
Cool it with your moral authority.
