The use of e-cigarettes among high school students served as a significant predictor that they would subsequently smoke traditional cigarettes, according to a study published in the January 2018 issue of Pediatrics. Yet the reverse did not hold true among students who reported using traditional cigarettes, as this did not predict future use of e-cigarettes, according to the study, "Trajectories of E-cigarette and Conventional Cigarette Use Among Youth," (published online Dec. 4). Researchers followed 808 students in three public high schools in Connecticut, and analyzed the results of longitudinal surveys that students submitted in 2013, 2014 and 2015 that reported their past-month's use of e-cigarettes and traditional cigarettes.
The study found that the frequency of both e-cigarette use and traditional cigarette use also increased over time. The authors suggest more research is needed to develop effective e-cigarette regulation and prevention programs.
