BackgroundThe proliferation of electronic vaping products raises many concerns, including whether these products will lead to risky behaviors among adolescents. Evidence suggests that e-cigarettes may be used to vaporize cannabis (marijuana). The current study examined associations between e-cigarette use, dual use of e-cigarettes and tobacco cigarettes, and frequency of cannabis use.MethodsData on high school students (grades 9–12) were from the 2014–2015 Canadian Student Tobacco, Alcohol and Drugs Survey (n=23,429 respondents). Multinomial logistic regression analyses were used to examine frequency of cannabis use among those who reported using only e-cigarettes, only tobacco cigarettes, both products, and nonusers.ResultsApproximately 15% of respondents reported using cannabis at least once in the past month. Likelihood of using cannabis was significantly higher for e-cigarette only and cigarette- only users. Users of both products had increased odds for a higher frequency of cannabis use. These results indicated a sequential risk gradient in the use of cannabis for dual use, cigarette only, e-cigarette only, and non-use groups, respectively.ConclusionsYouth who reported use of e-cigarettes, tobacco cigarettes, and both products showed a heightened risk of using cannabis more frequently.
