Note: CIG=cigarettes only; NCC=non-cigarette combustibles only; NC=non-combustibles only; NCC&NC=dual non-cigarette combustibles and non-combustible; CIG&NC=dual cigarettes and non-combustibles; CIG&NCC=dual cigarettes and non-cigarette combustibles; POLY=poly-tobacco. Unadjusted means and confidence intervals (CI) are presented. Estimates are adjusted for age, gender, race/ethnicity, and education. Tobacco product use in dual and poly-tobacco use T-PUPs were compared to corresponding single product category T-PUPs (e.g., CIG&NC, CIG&NCC, and POLY were compared to CIG).
