Our sample was comprised of participants who completed interviews for both assessments from the National Epidemiological Survey on Alcohol and Related Conditions (NESARC), a nationally representative, prospective longitudinal survey conducted by the National Institute on Alcohol Abuse and Alcoholism (NIAAA). As described elsewhere (Dawson et al., 2007; Grant et al., 2003a; Grant and Kaplan, 2005), the NESARC was collected via computer assisted personal interviews with civilian, non-institutionalized adults (≥18 years of age), residing in the U.S. over two waves (Wave I, 2001–2002, n = 43,093, 81% of those eligible; Wave II 2004–2005, n = 34,653, 86.7% of wave I participants). African Americans, Hispanics, and adults aged 18–24 were oversampled. The NESARC procedures were reviewed and approved by the U.S. Census Bureau and the U.S. Office of Management and Budget and all participants gave informed consent. State level smoke-free policy data was obtained from the American Nonsmokers’ Rights Foundation Ordinance Database (ANR, 2012).
