Leto,
My intent was speaking strictly of bars and restaurants excluding casinos. However, some Las Vegas casinos have smoking bans in their restaurants. It’s true that casinos are totally different because it seems gambling, smoking and drinking go hand in hand. As a matter of fact I read a study once where smokers and drinkers gamble more often than non-smokers and non-drinkers. It’s doubtful that Nevada would enact a smoking ban in public buildings either. California has banned smoking in all public buildings except Native American casinos. A state of the art air exchange and ventilation system would be a great improvement though.
