So liberal society its bad to smoke unless it cannibas, or maybe even crack, then you're just doing you thing, harming no one, engaging in a victimless crime with no down side.
People with these gems got to be smoking, there just isnt any other explanation. Unless, of course, "crazy".
I don't think anyone can dispute the fact that smoking crack is absolutely terrible for you and has significantly worse physical and societal effects than weed or tobacco. To say otherwise wouldn't be a liberal position; it would be idiocy.
