Note. The percentages adopting a smoke-free policy presented in this table differ from those shown in Figure 1 because these results are restricted to the subpopulation of smokers who did not have a smoke-free home policy in 2001, whereas the data in Figure 1 are among all smokers.

^aResults from a logistic regression controlling for sex, age, race, income, education, amount smoked, time to first cigarette, and other household smokers.

*Statistically significant at the 5% level.
