The primary purpose of smokefree laws and policies is to protect people who do not smoke from secondhand smoke.1 However, smokefree laws can also motivate and help tobacco users quit and prevent initiation of tobacco use. Studies have shown that the implementation of smokefree laws and policies can increase cessation and reduce smoking prevalence among workers and the general population1-6 and may also reduce smoking initiation among youth.1,7

U.S. Surgeon General

\n

In 2014, the U.S. Surgeon General concluded that smokefree laws in workplaces and communities help smokers quit and reduce tobacco use. In addition, smokefree workplaces and communities make youth and young adults less likely to start smoking due to a number of factors, including lower visibility of people who smoke, fewer opportunities to smoke alone or with others, and reduced social acceptability for smoking. The implementation of smokefree laws also increase the adoption of voluntary smokefree rules in homes, which can further protect those who do not smoke\u2014especially those most vulnerable that are exposed to secondhand smoke in the home, such as children.1

\n

Residents of multi-unit housing, like apartments or condos, are particularly likely to be exposed to secondhand smoke. Approximately 25% of the U.S. population lives in public or private multi-unit housing.8,9 In 2016, the U.S. Department of Housing and Urban Development finalized a rule requiring public housing authorities to prohibit smoking in their buildings, including in residents\u2019 units. The policy was combined with promotion of tobacco cessation and cessation resources. Promoting cessation services together with smokefree policies in multi-unit housing could help motivate those who smoke to quit, and may encourage more private multi-unit facilities to adopt smokefree policies.10

Task Force on Community Preventive Services

\n

In 2010, a systematic review by the Task Force on Community Preventive Services reported that:2

\n
    \n
  • Eleven studies found that smokefree laws and policies in workplaces were associated with a median 6.4% increase in tobacco use cessation.
    • \n
  • Twenty-one studies found that these laws and policies were associated with a median 3.4% decrease in tobacco use prevalence.

International Agency for Research on Cancer

\n

In 2009, a report by the International Agency for Research on Cancer on the effects of smokefree laws concluded that:3

\n
    \n
  • There is sufficient evidence (the highest level of evidence under the report\u2019s rating scale) that smokefree workplaces reduce cigarette consumption among people who continue to smoke.
    • \n
  • There is strong evidence (the second highest level of evidence) that smokefree workplaces lead to increased successful cessation among people who smoke.
    • \n
  • There is strong evidence that smokefree policies reduce tobacco use among youth.
    • \n
\n

Cochrane Review

\n

In 2010, a Cochrane review of 23 studies of smokefree laws reporting measures of active smoking reported:4

\n
    \n
  • There was no consistent evidence of a reduction in smoking prevalence attributable to these laws.
    • \n
  • However, total tobacco consumption was reduced in studies where smoking prevalence decreased.

Australian, Canadian, German, and U.S. communities (2002)6A smokefree workplace policy: \n
    \n
  • Reduces smoking prevalence by 3.8% among employees who smoke

Effects of Reduced Smoking Among Youth

\n Effects of Reduced Smoking Among Youths \n
Studies in:Found that:
Massachusetts (2008)7Youth living in towns with laws making restaurants smokefree were less likely to progress to established smoking than youth who lived in towns with weak smoking restrictions (odds ratio: 0.60, 95% confidence interval: 0.42\u20130.85).

This effect was found to be entirely due to a reduced likelihood of progressing from experimentation with smoking to established smoking.
