This study examines the relationships between self-reported exposure to smokeless tobacco marketing and initiation/onset of smokeless tobacco use/susceptibility at 6-month follow-up, among a cohort of young adults in urban Texas.Participants were 3597 18-25 year old never smokeless tobacco users, attending 24 Texas two-year colleges and four-year universities. A multi-level, multivariate logistic regression model, accounting for school clustering, examined the impact of self-reported recall of smokeless tobacco marketing exposure at baseline and subsequent initiation of smokeless tobacco use. A subsample analysis of non-susceptible never users (n = 3097) examined the impact of self-reported exposure to smokeless tobacco marketing at baseline and onset of susceptibility to use smokeless tobacco. Both outcomes were assessed at 6-month follow-up. Baseline covariates included age, race/ethnicity, sex, two-/four-year institution, and other tobacco use. For the full analysis, susceptibility to use smokeless tobacco at baseline was included as a covariate.From baseline to 6-month follow-up, 6.1% of never users initiated smokeless tobacco use (n = 219) and 7.0% of non-susceptible never users became susceptible to smokeless tobacco use (n = 221). Self-reported recall of smokeless tobacco marketing exposure at baseline was associated with initiation of smokeless tobacco (Adj OR: 1.17; 95% CI: 1.08-1.27) and onset of susceptibility to use smokeless tobacco (Adj OR: 1.11; 95% CI: 1.02-1.21) at 6-month follow-up, controlling for all covariates.Findings build on previous research by demonstrating an association between recall of smokeless tobacco marketing and subsequent use. Findings are concerning given the 300% increase in smokeless tobacco marketing expenditures from 2006 to 2016.
