Analytic sample includes individuals with harm perception recorded in Wave 1 and Wave 2 for at least one tobacco product and complete data on adjustment variables (N=7370).

Adjustment variables: gender (female vs. male), age group (15–17 vs. 12–14 years), race/ethnicity (Hispanic/Latino, Non-Hispanic Black, Non-Hispanic White, other), US Census region (Northeast, Midwest, South, West), sensation seeking score (range: 3–15), home tobacco use (yes/no), alcohol ever use (yes/no), tobacco advertisement receptivity (yes/no), parental education attainment (at least some college vs. less), baseline perceived harm, and initiation of each other tobacco product type.

Smokeless tobacco includes conventional moist snuff or chewing tobacco, snus, and dissolvable tobacco. Other combustible tobacco includes cigars, pipes, bidis, and kreteks.
