Smoking has been shown to promote gambling, even prompting people to “crave” the pastime, according to a University of Connecticut study. While indoor smoking is prohibited in other parts of the country, gamblers can still light up in Las Vegas casinos, much to the chagrin of non-smokers.Ĭasinos defend their smoking policy because it benefits their bottom line. With the exception of tobacco businesses, strip clubs, private houses, select stand-alone bars, and, of course, casinos, the Nevada Clean Air Act prohibits smoking indoors.
