At many colleges, smokers are being run not just out of school buildings but off the premises. On Nov. 19, the University of Kentucky, the tobacco state’s flagship public institution, launched a campus wide ban on cigarettes and all other forms of tobacco on school grounds and parking areas. Pro-nicotine students staged a "smoke-out" to protest the new policy, which even rules out smoking inside cars if they’re on school property.
Kentucky joins more than 365 U.S. colleges and universities that in recent years have instituted antismoking rules both indoors and out. In most places, the issue doesn’t seem to be secondhand smoke. Rather, the rationale for going smoke-free in wide open spaces is a desire to model healthy behavior.
Purdue University, which has 30-ft. buffer zones, recently considered adopting a campus wide ban but tempered its proposal after receiving campus input. Smoking will now be restricted to limited outdoor areas.
A. a tobacco shop
B. a school cafeteria
C. an organic food store
D. an unhealthy food chain
