It seems to be still perfectly normal for people to smoke in Las Vegas Casinos. A recent NYTimes report uncovered that the public smoking ban was not enforced in casinos. The casino staff is pressing for change alarmed by the 2nd hand smoke they have to breath in everyday at work. Many casino is argue it would be bad for their revenue if they ban smoking but is that really the case?
Anyway if you do not want to sit in a smoked up environment I would recommend to play instead at a casino online. Online casinos such as Casino Classic and Casino Action, have other advantages as well. They often are cheaper and let you play for free if you use an online casino bonus.Might be the better option until Las Vegas casinos kick out smoking.
