It would be pretty hard to find someone who hadn’t smoked pot in their youth. I gave that up 25 years ago but I am not trying to hide the fact that I smoked pot in my youth. Pot makes people stupid and lazy but it should not be illegal just as alcohol makes people bad drivers and meth makes people into tweakers. None of it should be illegal and the problems of drugs should be addressed as social issues not legal issues.
Crimes comitted in order to maintain a drug habit are most assuredly legal issues. Some are violent.
