The key to it should always be adequate ventilation. I was always raised to never go into a building smoking a cigarette and anytime I went into any building I always put out my cigarette. There is a town here in Arkansas which does not allow smoking even on your own front porch, now that is going too far. The California law is ridiculous too, not allowed to smoke anywhere in public. The problem is that people are getting too lazy and want the government to do everything for them instead of dealing with little problems themselves. I have a problem with people wearing the pants halfway down to their knees as well but I do not want to make a law to stop it. Don't make laws to stop behavior unless it infringes on other people rights. Repeal the seat-belt law.
