There are those who hate cigarette smokers and who are proto-fascist when it comes to others not toeing the line of their own peculiar form of moral codex. You’ll meet them. They’re tolerable in a forum, but if you’d meet them in a dark alley, keep your hand on the safety.
I don't smoke, can't stand it, don't think it's wise, but I can't see any justification for banning it or essentially taxing it out of existance except greed and/or tyranny. Life is awful short to be legislating folks from such an activity.
