Securing clean indoor air laws is a major tobacco control accomplishment of the past 15 years. The public quickly adopted and supported such policies both in public and private spaces. Clean indoor air is now threatened by the emergence of e-cigarettes. E-cigarette aerosol contains nicotine, heavy metals, and carcinogens, and the long-term effect of secondhand exposure is unknown. Surveillance is necessary to track voluntary rules on smoking and vaping in the home. The Minnesota Adult Tobacco Survey (MATS) is a series of cross-sectional, random-digit-dial telephone surveys on smoking, vaping, and other tobacco-related behaviors, attitudes, and beliefs among Minnesota adults. MATS measured voluntary smoke-free rules in the home in 2014 (N = 9,304) and measured both smoke-free and vape-free home rules in 2018 (N = 6,055). The prevalence of smoke-free home rules among Minnesota adults in 2018 was 91.5% (95% CI, 90.5%-92.5%), up slightly from 89.3% (95% CI, 88.4%-90.2%) in 2014. In comparison, 84.0% (95% CI, 82.7%-85.3%) reported vape-free home rules. Although 70.0% (95% CI, 66.0%-73.0%) of smokers in 2018 reported smoke-free home rules, only 23.3% (95% CI, 15.0%-31.6%) of e-cigarette users reported vape-free home rules. Living with children younger than 18 years significantly increased the odds of having smoke-free and vape-free home rules. Although widespread adoption of voluntary smoke-free and vape-free home rules demonstrates a positive change in social norms, most e-cigarette users allow vaping in their homes, including those who live with children younger than 18. Tracking voluntary smoke-free and vape-free home rules and efforts to encourage them are important to improve the public's health.
