BACKGROUND: Smoke-free laws reduce disease prevalence. The impact of municipal smoke-free laws on lung cancer incidence in Kentucky was examined. The authors hypothesized that lung cancer incidence rates would be associated with the strength of smoke-free laws. METHODS: This was a secondary analysis of 83,727 Kentucky residents aged ≥ 50 years who were newly diagnosed with lung cancer from 1995 to 2014. In 2014, 33 municipalities had 1 or more smoke-free laws. County-level characteristics included adult smoking rate, sex, race/ethnicity, income, physician supply, observed radon values, and rurality. RESULTS: Individuals living in communities with comprehensive smoke-free laws were 7.9% less likely than those living in communities without smoke-free protections to be diagnosed with lung cancer. The difference in lung cancer incidence between counties with moderate/weak laws and those without laws was not significant. CONCLUSIONS: Comprehensive smoke-free laws were associated with fewer new cases of lung cancer, whereas weak or moderate smoke-free laws did not confer the same benefit. One hundred percent smoke-free laws, covering all workers and the public with few or no exceptions, may be key in reducing new cases of lung cancer. Cancer 2018;124:374-80.
