The second series of events began in the mid-1970s. In 1973, Arizona passed a comprehensive law that limited smoking in public places, the first effort to formally control public smoking. This was followed by a more restrictive set of laws including the 1975 Minnesota Clean Indoor Air Act, which required restaurants to have nonsmoking sections; another twelve years would pass until Aspen, Colorado, became the first city to formally ban all cigarette smoking in restaurants. The push for bans in all restaurants was bolstered by the nineteenth Surgeon General’s Report (USDHHS 1986), which argued that the “simple separation of smokers and nonsmokers within the same airspace may reduce but cannot eliminate nonsmoker exposure to environmental tobacco smoke” (p. 7).
