A blueprint for assessing public support of citywide smoke-free legislation.

The tracking of public opinion can be a critical component of antitobacco campaigns, such as efforts to enact citywide Clean Indoor Air legislation. Grassroots tobacco control coalitions that work locally to promote smoke-free environments typically encompass individuals from a wide range of public health fields. Although knowledgeable, volunteer groups lack the financial resources to evaluate the impact of local efforts or determine their community's level of support for potential legislation. The steps taken by a grassroots organization to conduct a public opinion survey are outlined, including methodological, analytical issues, and resource requirements. A valid survey can be completed in 4 months with minimal financial resources. Individuals willing to voluntarily administer and analyze a survey can be identified at the local level. Results of a tobacco-related public opinion survey can be instrumental in the promotion of smoke-free environments and an effective tool in attracting media coverage.
