Teenagers who smoke the popular electronic cigarettes (e-cigarettes) are less likely to use substances than adolescents who use both cigarettes and e-cigarettes (dual users) but more likely to use them than teenagers who have never used either product (nonusers).
Teenagers who smoke electronic cigarettes (e-cigarettes) are less likely to use substances than adolescents who use both cigarettes and e-cigarettes (dual users) but are more likely to use them than teenagers who have never used either product (nonusers). This was one of the primary findings of a school-based survey of 1941 high school students (mean age, 14.6 years) in Hawaii. In addition to addressing the prevalence of smoking e-cigarettes and cigarettes, the survey assessed psychosocial and demographic variables as well as perceived health effects of e-cigarettes.
A full 96% of participants were aware of e-cigarettes; 67% considered them healthier than cigarettes. Of students surveyed, 68% were nonsmokers; 17% used e-cigarettes alone; 12% used both cigarettes and e-cigarettes; and 3% used cigarettes only. Dual users and cigarette-only users had the highest risk status for substance use compared with e-cigarette users and nonusers.
For example, compared with dual users, e-cigarette-only smokers had fewer known risk factors for substance use (such as conflicts with parents, sensation seeking, and rebelliousness) and more protective factors (such as parental support and emotional self-control). However, compared with nonusers, e-cigarette-only smokers had more risk factors and fewer protective factors. In other words, the risk status-levels of risk and protective factors--of e-cigarette-only smokers was in between those of nonusers and dual users (Wills TA, et al. Pediatrics. 2015;135:e43-e51).
Commentary: In this survey of ninth and tenth graders, 29% of students have used either e-cigarettes or e-cigarettes and traditional cigarettes. Other studies have confirmed a rapid increase of “vaping,” often in children. I find it alarming that so many young people are adopting this practice. We need to know more about the long-term effects of vaping and we need the US Food and Drug Administration to regulate this $11.7 billion industry while we await answers. -Michael G Burke, MD
