Three casinos in Colorado are claiming that the state?s smoking ban does not apply to them because they are ?cigar-tobacco bars,? which are exceptions to the law, which went into effect at the start of the year. The city of Cripple Creek, where the three casinos are located, claims that the law is written so ambiguously that it doesn?t feel comfortable enforcing the ban against the casinos, which claim that it doesn?t apply to them. The city has a total of 14 casinos. The casinos making the claim say that they sell enough tobacco?5 percent of total sales?to qualify for the exemption. A casino in Black Hawk also is making the claim.
