Nicotine Dependence and Its Impact on Poly-Tobacco Use Among US Adults.

ABSTRACT:

Background

Poly-tobacco use (PTU), the consumption of multiple tobacco products, is linked to higher mortality rates compared to single product use. Existing cross-sectional studies have demonstrated a relationship between PTU and nicotine dependence (ND).

A standardized ND score, calculated from 16 items, was assigned to each participant at baseline. ND was treated as a continuous variable ranging from 1 (least dependent) to 5 (most dependent).
