Property owners have been sued by people who claim they can smell smoke more than 100 yards away. So where does it stop?
At the property line. At the city limits line? At the county line? At the state line? Smoking is only step one in a long process of allowing government to dictate a long list of what people can and can't do.
Tolerance is the key issue here. Not government intervention. If we allow government to control any aspect of our lives with a legal product, it won't stop with just smoking.
Oh but wait! The government already has their teeth into private businesses by forcing smoking bans on them. It has already started.
