  • Note: CI = confidence interval, ref = reference category, RR = relative risk.

  • * Sample sizes for unadjusted analyses were 2471 overall, 2143 for premium/discount brands, and 328 for contraband cigarettes; sample sizes for adjusted analyses were 2068, 1813 and 255, respectively. The total number of people who switched brands was 152 for premium/discount and 37 for contraband.

  • Population-weighted estimates.

  • Adjusted for all covariates listed in Table 1.

  • § Because only 1 respondent switched from contraband to premium/discount cigarettes and reported a period of 30-day cessation, the contraband portion of the analysis was omitted.
