Concern over the detrimental effects of secondhand tobacco smoke on nonsmokers has grown in recent years. The U.S. Environmental Protection Agency classified secondhand tobacco smoke as a known cause of cancer in humans in a December 1992 report. In an effort to reduce the risk of tobacco smoke-related health problems in Colorado, the General Assembly passed the Colorado Clean Indoor Air Act (“act”) in 2006, which prohibits tobacco smoking in indoor areas throughout the state.1 As of March 31, 2016, 25 other states have also banned tobacco smoking in restaurants, bars, and workplaces.2
