What about the alcoholics, or the generally drink too much bunch. Domestic violence is usually committed by drunks, have you ever heard of a brawl amongst pot smokers as you do in most city pubs and clubs at some time or other. I don't take drugs, i work with alkies and junkies, the only difference is that drugs are illegal and the alkies sit still for longer. But if the governmant spent as much money encouraging youngsters to not take drugs or drink as they do punishing the criminals and hopeless cases that evolve from it all, we would all be better off.
By the way, you can expect a knock at your door sometime if you are promoting the idea of "screw you i don't like the way you live" coz someone will one day take exception to what you do, however innocuous it would appear to others, what goes around comes around
