The Latinx population in the United States (U.S.) experiences significant tobacco and other substance userelated health disparities. Yet, little is known about the couse of combustible cigarettes and e-cigarettes (dual use) in relation to substance use behavior among Latinx smokers. The present investigation compared English-speaking Latinx adults living in the United States who exclusively smoke combustible cigarettes versus dual users in terms of alcohol use and other drug use problem severity. Participants were 297 Hispanic/Latinx daily cigarette smokers (36.4% female, Mage = 35.9 years, SD = 8.87) recruited nationally across the United States using Qualtrics Panels to complete self-report measures of behavioral health outcomes. Five analysis of covariance models were conducted to evaluate differences in overall alcohol consumption, dependence, related problems, hazardous drinking, and drug use problem severity between exclusive combustible cigarette smokers (N = 205) and dual users (N = 92). Results indicated that dual users evinced greater levels of alcohol consumption, dependence, alcohol-related problems, and hazardous drinking compared to exclusive combustible cigarette smokers (ps <.001). Dual users also reported greater levels of drug use problems relative to exclusive combustible cigarette smokers (p <.001). The current findings are among the first to document that dual cigarette and e-cigarette use status (compared to exclusive combustible cigarette smoking) may serve as a clinically relevant risk indicator for a range of deleterious substance use problems among Latinx individuals. Future research is needed to corroborate these findings and examine dual-use status as a longitudinal predictor of alcohol and other substance-related problems.
