It's a burning issue that's heating up the American Gaming Association.
Its executives want to ban smoking in casinos across the country, including right here in northern Nevada.
One New Jersey study concluded it could cost Atlantic City $93 million annually.
Some smokers visiting the biggest little city this Christmas say they wouldn't come back if they couldn't smoke in casinos. They would go to California to the Indian gaming casinos where they allow smoking.
A few of the smokers say cigarettes and gambling don't necessarily go hand in hand.
They understand secondhand smoke can kill you, and they don't want to endanger the lives of other tourists as well as casino workers.
And speaking of casino workers; Chair of Nutrition Department at the University of Nevada Chris Pritsos says they're five times as likely to come down with cancer or heart disease than other workers in smoke-filled environments.
