A subsample of 5776 respondents to the California Tobacco Survey who do not smoke and work indoors outside of their home was analyzed regarding worksite smoking policy and worksite exposure to environmental tobacco smoke. To obtain study results, survey responses were linked to tobacco ordinance data. Nonsmokers who worked in localities with moderate or strong laws were more likely to report worksite smoking policies than nonsmokers in localities without laws. Even in localities with strong laws, 23.5% of respondents reported no worksite policy, and 26.4% reported recent exposure to environmental tobacco smoke at the worksite. Comprehensive laws with minimal exemptions may be necessary to ensure adequate compliance and protection from environmental tobacco smoke.
