AOR = adjusted odds ratio; CI = confidence interval; HSI = Heaviness of Smoking Index; OR = odds ratio. All logistic regression analyses adjusted for time in sample. Demographics include age, sex, household income and education. Bolded text indicates significance of P < .05.

^aAbstinence = abstinence from cigarettes.
