Weighing the Risks and Benefits of Electronic Cigarette Use in High-Risk Populations.

Abstract

This article reviews the current evidence on electronic cigarette (e-cigarette) safety and efficacy for smoking cessation, with a focus on smokers with cardiovascular disease, pulmonary disease, or serious mental illness. In the United States, adult smokers use e-cigarettes primarily to quit or reduce cigarette smoking. An understanding of the potential risks and benefits of e-cigarette use may help clinicians counsel smokers about the potential impact of e-cigarettes on health.
