Abstract
Tobacco is widely recognized as a leading cause of cardiovascular morbidity and mortality, accounting for approximately seventeen percent of all cardiovascular disease deaths globally. Electronic nicotine delivery systems such as e-cigarettes have been developed and advertised as safer alternatives to traditional tobacco cigarettes. Aggressive marketing strategies, as well as misleading claims by manufacturers, have largely contributed to the belief that e-cigarettes are harmless. In reality, e-cigarettes are far from innocuous. E-cigarette solutions and aerosols generally contain harmful substances that are commonly found in tobacco cigarette emissions. A growing body of literature suggests that e-cigarettes are associated with an increased risk of cardiovascular morbidity and mortality. In addition, the effectiveness of e-cigarettes as smoking cessation tools has yet to be determined. Concerningly, most smokers do not give up on tobacco cigarettes and eventually become dual users. Unregulated, e-cigarettes constitute a serious threat to established tobacco control policies. Fortunately, many countries have demonstrated that strong regulations were effective in protecting their populations from the dangers of e-cigarettes. The World Heart Federation recommends applying the precautionary principle and a set of measures to protect vulnerable populations, prevent exposure to second-hand smoking, and address misleading claims. In this regard, we recommend that governments, policymakers, and other relevant stakeholders enact or support the following measures, among others: Prohibit the sale and distribution of e-cigarettes to minors, as well as the use of flavouring agents.Prohibit the use of e-cigarettes anywhere tobacco cigarettes have been banned.Prohibit marketing, advertising, and misleading claims regarding e-cigarettes.Apply excise taxes on e-cigarettes.Conduct more research regarding the long-term effects of e-cigarettes on cardiovascular health. Lastly, countries that have banned the commercialization of e-cigarettes should maintain these measures.
