Modeling the Public Health Impact of E-Cigarettes on Adolescents and Adults

TL;DR

This paper develops a dynamical systems model to analyze how e-cigarettes impact smoking prevalence among adolescents and adults, assessing whether vaping offers net public health benefits or harms.

Contribution

It introduces a novel mathematical model to evaluate the competitive dynamics between traditional and electronic cigarettes and their societal health impacts.

Findings

E-cigarettes can reduce traditional smoking prevalence under certain conditions.

Vaping may attract non-smokers, potentially increasing overall health risks.

The model identifies parameters where e-cigarettes are beneficial or harmful.

Abstract

Since the introduction of electronic cigarettes to the United States market in 2007, vaping prevalence has surged in both adult and adolescent populations. E-cigarettes are advertised as a safer alternative to traditional cigarettes and as a method of smoking cessation, but the U.S. government and health professionals are concerned that e-cigarettes attract young non-smokers. Here, we develop and analyze a dynamical systems model of competition between traditional and electronic cigarettes for users. With this model, we predict the change in smoking prevalence due to the introduction of vaping, and we determine the conditions under which e-cigarettes present a net public health benefit or harm to society.
