AOR = adjusted odds ratio; CI = confidence interval; Reference groups of covariates were older young adults (aged 25–29), racial/ethnic minority, male, two-year college students, non-current marijuana use, and non-past 14-day binge drinking; Reference group of cigarette smoking intensity is heavier smoker. ATP=alternative tobacco product.
