CHEYENNE, Wyo. -- The University of Wyoming's Survey and Analysis Center says an anti-tobacco program in Wyoming is showing some success.

The center says that for every $1 million invested in the Tobacco-Free Wyoming Communities program, cigarette sales have decreased by 2.2 million packs.

The center also estimates that the program saves $650,000 a year in health care costs.

Nanette Nelson with the Survey and Analysis Center says cigarette sales are on the decline in most Wyoming counties. Sales in Albany County, for example, have dropped from an average of 70 packs per person in the 1990s to 50 packs now.

Cigarette sales are up in Campbell County. Nelson attributes that to an influx of workers in the energy industry over the past decade.
