Electronic cigarettes (e-cigarettes) were originally developed in 2003 as healthier alternatives to conventional tobacco cigarettes. Their popularity has since significantly increased and both users and nonusers are exposed to their aerosol and product constituents. Although some evidence suggests that e-cigarette use may facilitate smoking cessation, definitive data are lacking and e-cigarettes are not approved by the Food and Drug Administration as a cessation aid. While e-cigarette aerosol contains fewer toxins than conventional cigarette smoke, studies evaluating whether e-cigarettes are less harmful are inconclusive. The health impact of e-cigarettes for both users and nonusers cannot be determined with currently available data, and there are both environmental concerns and issues regarding nonuser exposure. Most of the currently available data related to the health effects of e-cigarettes do not evaluate their effects on the general population and evidence regarding the systemic health effects of e-cigarettes is limited. In addition, there has been a recent rise in vaping-related lung injuries. Therefore, the detrimental effects of e-cigarette use should be further investigated, and every effort should be made to increase public awareness of the harmful effects of e-cigarettes.

电子烟：一种新颖的疗法或迫在眉睫的灾难


电子香烟（电子烟）最初是在2003年开发的，是传统烟草香烟的更健康的替代品。此后，它们的受欢迎程度显着提高，使用者和非使用者都暴露于其气雾剂和产品成分中。尽管一些证据表明，使用电子烟可能有助于戒烟，但缺乏确切的数据，并且美国食品和药物管理局未批准将电子烟用作戒烟辅助工具。尽管电子烟气雾剂比常规香烟烟雾所含的毒素更少，但评估电子烟是否危害较小的研究尚无定论。电子烟对使用者和非使用者的健康影响无法通过当前可用数据来确定，并且存在环境问题和与非使用者接触有关的问题。目前有关电子烟健康影响的大多数可用数据并未评估其对普通人群的影响，有关电子烟对系统健康的影响的证据有限。此外，最近与雾相关的肺损伤有所增加。因此，应进一步研究电子烟的有害作用，并应尽一切努力提高公众对电子烟有害作用的认识。
