액상형 전자담배의 호흡기 건강 영향

Abstract

Electronic cigarettes (e-cigarettes) are battery-powered nicotine delivery systems that generate an inhalable aerosol containing nicotine, flavors, propylene glycol, and vegetable glycerin. Even though there is little evidence on e-cigarettes’ safety and effectiveness as a smoking cessation aid, e-cigarette usage has drastically increased globally. E-cigarettes reached the market without extensive preclinical toxicology testing or long-term safety trials that would be required of conventional therapeutics or medical devices. In August 2019, several cases of e-cigarette or vaping use-associated lung injury have been reported in the United States and this outbreak reminded the potential health risks of e-cigarette. Herein, we review the evidence on the effects of e-cigarettes on respiratory health.
