(Radio Iowa) – A coalition of groups is celebrating the 15th anniversary of the state law that banned smoking in most public places and urging lawmakers to do more. Threase Harms of the Iowa Tobacco Prevention Alliance says the adult smoking rate has fallen 33 percent since the Iowa Smokefree Air Act passed. Representatives from the American Lung Association, the American Cancer Society and the American Heart Association are calling on lawmakers to increase the state tax on tobacco products and close a loophole that allows smoking on the gaming floors at the state’s casinos.

The coalition also wants e-cigarette use banned in the same places where it’s not legal to smoke a cigarette or a cigar.
