A new study for the Wyoming Department of Health says more people quit smoking in communities that have enacted strong laws against smoking in public places.

The study by the Survey and Analysis Center at the University of Wyoming comes as Wyoming lawmakers prepare to revisit a possible statewide smoking ban.

The study sums up previous findings about smoking and secondhand smoke. One is that smokers who live in communities with strong ordinances against public smoking are 38 percent more likely to quit than smokers in communities without such laws.

Cheyenne, Laramie and Evanston have banned smoking in bars and restaurants in recent years. Previous attempts to pass a statewide smoking ban have made little headway in the Legislature.
