News release: "Thirty of America’s 50 largest cities are now covered by laws that prohibit smoking in all indoor areas of private workplaces, restaurants, and bars, according to a study from the Centers for Disease Control and Prevention. By late 2000, only one of the 50 largest U.S. cities—San Jose, Calif.—was covered by such a law. As of Oct. 5, 2012, 16 of the 50 largest cities were covered by local comprehensive smoke-free laws, and 14 more were covered by state comprehensive smoke-free laws. Today, almost half of Americans are protected by state or local laws of this kind, compared to less than three percent in 2000. Scientific studies have found that smoke-free laws reduce exposure to secondhand smoke, reduce smoking, and improve health, including reducing heart attacks. While new local comprehensive smoke-free laws continue to be adopted in a number of cities and counties, last week North Dakota voters approved the first statewide comprehensive smoke-free law adopted since 2010."
