Health effects of electronic cigarettes

E-cigarettes cause harm to adolescent users. The devices and constituents create multiple substances which are toxic on inhalation, including nicotine, metallic nanoparticles, particulate matter, and carbonyls. In addition, there is a robust relationship between youth vaping and use of combustible cigarettes as adults. This finding is based on longitudinal research and is found among youth who were at low risk for use of combustible cigarettes. Therefore, the most substantially confirmed health hazard of youth vaping is creating a new generation of smokers of combustible cigarettes and the documented health risks of such use. The physiological and psychological harms of nicotine dependence during adolescence also have been well documented. Additionally, population-based research has shown a consistent link between current vaping and respiratory issues during adolescence itself. Significant lung disease (EVALI) has occurred in adolescents and not all cases are linked to vitamin E acetate. Finally, extrapolating research on adults to adolescents raises the possibility that e-cigarette use is linked to pre-symptomatic cardiovascular dysfunction and may have a significant health impact during adulthood. The combination of this evidence, from pre-clinical to population-based longitudinal studies, conclusively demonstrates that e-cigarettes are not safe for youth.
