We conducted a longitudinal study among Oregon households with at least one smoker to assess smoking-related associations with ban adoption, to examine smoker support for bans, and to examine barriers to ban establishment. We followed a cohort of 1,604 baseline survey respondents for a median time of 21 months and re-interviewed 825 respondents (51.4% response rate). Of these, 512 did not have a full household ban in place at baseline. Thirty-two percent of the respondents without a ban at baseline adopted a full ban. Baseline smoking-related factors associated with ban adoption were: longer time until first cigarette, stage of change, and attitudes towards respondent's smoking. Associated follow-up factors included cessation and reduced consumption. Ninety-one percent of respondents reported smoker support of a ban. Future work should focus on ban establishment in households with more highly addicted smokers.
