Introduction: The present study reports on the prevalence of smoke-free homes, the characteristics of participants who adopted a smoke-free home policy, and the association between smoke-free homes and subsequent predictors of smoking cessation.

Methods: Data are reported on 4,963 individuals who originally participated in the Community Intervention Trial for Smoking Cessation between 1988 and 1993 and completed follow-up surveys in 2001 and 2005. The relationship between home smoking policy and smoking behavior was examined with a multivariate regression model.

Results: Among those who were smokers at the 2001 follow-up, the percentage reporting that no smoking was allowed in their home increased from 29% in 2001 to 38% in 2005. Smokers most likely to adopt smoke-free home policies between 2001 and 2005 were males, former smokers, and those who had lower levels of daily cigarette consumption (among those who continued to smoke), those with higher annual household incomes, and those with no other smokers in the household. Some 28% of smokers with smoke-free homes in 2001 reported that they had quit smoking by 2005 compared with 16% of those who allowed smoking in their homes (odds ratio [OR] = 1.7, 95% CI = 1.4-2.2), and baseline quitters with smoke-free homes also were less likely to relapse (OR = 0.6, 95% CI = 0.4-0.8).

Discussion: Smoke-free homes are becoming more prevalent, and they are a powerful tool not only to help smokers stop smoking but also to help keep those who quit from relapsing back to smoking.

Smoke-free home status from 2001 to 2005 among smokers in 2001 (N = 2,601). Respondents were asked, “What are the smoking rules or restrictions in your household”, if any? Those who responded, “smoking is sometimes allowed,” “smoking is allowed in some rooms only,” or “there are no rules about smoking in the house” were not considered to have a smoke-free home. Those who responded, “smoking is never allowed in the house” were considered to have a smoke-free home.
