Flavored electronic cigarette use and smoking among youth

Abstract

BACKGROUND AND OBJECTIVE: Flavored electronic cigarettes (e-cigarettes) are not prohibited in the United States, and e-cigarette flavors proliferate on the market. This study sought to examine flavored e-cigarette use and its association with smoking among youth. METHODS: Estimates of flavored e-cigarette use from the 2014 National Youth Tobacco Survey were investigated. A logistic regression model was used to assess whether flavored e-cigarette use was associated with (1) intention to initiate cigarette use among neversmoking youth (n = 16 471), (2) intention to quit tobacco use among current-smoking youth (n = 1338), and (3) perception of tobacco's danger among all respondents (n = 21 491). RESULTS: A total of 2017 respondents reported using e-cigarettes in the last 30 days, of whom 1228 (60.9%) reported using flavored e-cigarettes. Among never-smoking youth, 55.6% (288) of current e-cigarette users reported using flavored e-cigarettes. Among current smokers, 68.4% (495) of current e-cigarette users reported using flavored e-cigarettes. Compared with not using e-cigarettes in the past 30 days, using flavored e-cigarettes was associated with higher odds of intention to initiate cigarette use among neversmoking youth (adjusted odds ratio [aOR] = 5.7; P
