North Carolina (where I'm sitting as I type this) actually has some fairly restrictive smoking laws. In Raleigh (the capital), there is no smoking allowed in public buildings except for in sections of restaurants. Las Vegas has way more smoke in it than Raleigh does. Then again, Raleigh is a pretty urban place. It's definitely worse out in the country, where you can still find some high schools that have smoking sections for students (this speaks to both the rural acceptance of smoking, as well as to the number of high school students over the age of 18).
