Association of alcohol and drug use with use of electronic cigarettes and heat-not-burn tobacco products among Korean adolescents.

backgroundThe tobacco industry has aggressively introduced new and diverse products in the market, including electronic cigarettes (e-cigarettes) and heat-not-burn (HNB) tobacco products, to which adolescents are readily susceptible. Conventional cigarettes have a well-established relationship with adolescent risky behaviors such as alcohol and drug use; however, no studies exist on the association between alcohol consumption and use of e-cigarettes or HNB tobacco products among Korean adolescents. This study evaluated alcohol-related behaviors and drug use in relation to whether a Korean nationally representative adolescent sample had ever used e-cigarettes and HNB tobacco products.

methodsData from the 2018 Korean Youth Risk Behavior Web-based Survey were analyzed. The final study sample comprised 60,040 adolescents. Chi-square and logistic regression were used to examine whether the ever having used e-cigarettes and HNB tobacco products was associated with alcohol-related behaviors and drug use. P-values for trends were calculated to examine the dose-response relationship for each variable.

resultsRespondents with higher drinking frequency, drinking quantity, alcohol intoxication, alcohol availability, and drug use were more likely to report having used e-cigarettes and HNB tobacco products, thus implying a significant relationship between substance use and novel tobacco product (P < .001).

conclusionsOur findings suggest that at-risk adolescents who are engaged in other forms of risk-taking behaviors are prone to attract the experimentation with e-cigarettes or HNB tobacco products. Thus, smoking cessation programs related to substance use should be implemented, and there is an urgent need to monitor and regulate these products effectively.
