The best way to get people to quit smoking is to prevent them from getting really hooked in the first place.
That's the theory behind a new wave of anti-tobacco policies targeting some of the youngest smokers: college students.
From banning tobacco companies from advertising to kicking cigarettes off school grounds altogether, colleges are making it harder or even impossible to smoke on campus. The American Nonsmokers' Rights Foundation estimates there are about 700 smoke-free campuses around the country.
One of the pioneers in Alabama, Troy University, will go 100 percent smoke-free -- that means no smoking anywhere, indoors or out -- at its main campus starting in August.
