E-cigarettes can be ‘gateway’ to cigarettes for teens with no prior intention to smoke

A new study, published in the journal Pediatrics, finds that e-cigarette use is associated with a higher risk of cigarette smoking among adolescents who had no prior intention of taking up conventional smoking. These findings have strong implications for practice and policy, researches say.
Cigarette smoking remains a leading preventable cause of morbidity and mortality in the United States. And while adolescent cigarette smoking has declined over the past several decades, e-cigarette use presents a new risk for nicotine use disorder.
“Research is showing us that adolescent e-cigarette users who progress to cigarette smoking are not simply those who would have ended up smoking cigarette anyway,” says Olusegun Owotomo, M.D., Ph.D., M.P.H., the study’s lead author and a pediatric resident at Children’s National Hospital. “Our study shows that e-cigarettes can predispose adolescents to cigarette smoking, even when they have no prior intentions to do so.”
In one of the first theory-guided nationally representative studies to identify which adolescent e-cigarette users are at most risk of progressing to cigarette smoking, Researchers looked at data of more than 8,000 U.S. adolescents, ages 12-17, who had never smoked. The data was collected by the Population Assessment of Tobacco and Health (PATH) study, an NIH and FDA collaborative nationally representative prospective cohort study of tobacco use, from 2014-2016. Among adolescents who did not intend to smoke cigarettes in the future, those who used e-cigarettes were more than four times more likely to start smoking cigarettes one year later compared to those who did not use e-cigarettes.
