Exposure to secondhand smoke from burning tobacco products causes disease and premature death among people who do not smoke.1 There is no risk-free level of secondhand smoke, and even brief exposure can cause immediate harm.1 Studies have shown that smokefree laws that prohibit smoking in public places like bars and restaurants help improve the health of workers and the general population.1-17 Some of these improvements in health outcomes, such as reductions in hospital admissions for heart attacks, begin to be realized shortly after the laws take effect.1\u20135 Smokefree laws also can make it easier for people who smoke to quit, reducing their risk of disease.

Hospitality Workers\u2019 Health

\n

In 2009, a report by the International Agency for Research on Cancer concluded that there is sufficient evidence (the highest level of evidence under the report\u2019s rating scale) that implementation of smokefree legislation decreases respiratory symptoms in workers.4

\n
    \n
  • In 2009, a report by the International Agency for Research on Cancer concluded that there is strong evidence (the second highest level of evidence under the report\u2019s rating scale) that implementation of smokefree legislation causes a decline in heart disease morbidity.4
    • \n
  • In 2010, a report by the Institute of Medicine concluded that there is a causal relationship between smokefree laws and decreases in acute coronary events, although the report was unable to estimate the magnitude of this association.5
    • \n
  • In 2010, a Cochrane review of 12 studies found consistent evidence of a reduction in hospital admissions for cardiac events following implementation of smokefree laws.6
    • \n
  • In 2010, a meta-analysis of 17 studies of the effect of smokefree laws on acute coronary events reported a pooled estimate of relative risk of 0.90 (95% confidence interval: 0.86 to 0.94) and concluded that a large body of evidence exists supporting a reduction in acute coronary events following the implementation of smokefree laws, with the effect increasing over time.7
    • \n
  • In 2012, a random-effects meta-analysis of 45 studies of 33 smokefree laws with a median follow-up of 24 months (range: 2\u201357 months) found that comprehensive smokefree laws were associated with lower rates of hospital admissions or deaths for: \n
      \n
    • Coronary events (relative risk: 0.848)
      • \n
    • Other heart disease (relative risk: 0.610)
      • \n
    • Cerebrovascular accidents (relative risk: 0.840)
      • \n
    • Respiratory disease (relative risk: 0.760)
      • \n
    • \n
\n

The difference in risk did not change with longer follow-up. More comprehensive laws were associated with larger decreases in risk.8
