Abstract
INTRODUCTION: Cannabis - including blunts (cannabis rolled in tobacco-containing cigar casing) - is commonly the first substance used among adolescents, and may increase the likelihood of subsequent initiation of combustible tobacco products. METHODS: Data were pooled from two prospective studies of adolescents in California and Connecticut (total N=4,594). Logistic regression models assessed the association of baseline ever blunt use and ever non-blunt cannabis use (vs. never cannabis use) with subsequent initiation of any combustible tobacco-only product (i.e., cigarettes, cigars, or cigarillos) by one-year follow-up after adjustment for demographic characteristics and other tobacco product use at baseline. We also assessed whether estimates differed by prior e-cigarette or hookah use at baseline. RESULTS: Among never combustible tobacco-only product users (N=2,973), 221 (7.4%) had ever used a blunt and 114 (3.8%) had ever used only non-blunt cannabis at baseline. Blunt use (adjusted odds ratio (AOR)=1.98, 95% confidence interval (CI): 1.30, 3.01) and non-blunt cannabis use (AOR=2.38, 95% CI: 1.41, 4.00) were independently associated with greater odds of combustible tobacco-only product initiation by follow-up. Among those who had not tried e-cigarettes or who had not tried hookah, blunt use and non-blunt cannabis use were associated with significantly increased odds of combustible tobacco product initiation; among those who had tried e-cigarettes or hookah, the association was not significant. CONCLUSIONS: We found blunt and non-blunt cannabis use to be associated with subsequent combustible tobacco-only product initiation, particularly among adolescents who had not also tried other products containing nicotine.
