Background and Objectives: Electronic cigarettes are devices that heat liquids containing nicotine and chemicals to produce aerosols that can be inhaled. Although these products have been marketed as a less harmful alternative to traditional cigarettes, there is evidence indicating that their use also carries specific risks. Advertising and the influence of social media, particularly among young individuals, have led to increased consumption of these cigarettes and serious concerns. This study aimed to examine the benefits and drawbacks of electronic cigarettes.
Methods: In this narrative review, PubMed and Google Scholar databases were searched in a non-systematic manner using relevant keywords to identify studies related to the health effects, history, evolution, and cost-effectiveness of electronic cigarettes.
Results: Electronic cigarettes entered the market for the first time in 2003 and quickly gained popularity among consumers. These cigarettes were marketed as a healthier alternative to traditional cigarettes; however, they contain various chemicals, some of which decompose when heated, producing toxic compounds. Electronic cigarettes can have multiple impacts on health, including cardiovascular issues, respiratory problems, and the potential risk of cancer.
Conclusion: Electronic cigarettes may assist in smoking cessation in some cases, but significant drawbacks accompany these benefits. Given the potential risks, there is a need for further research to comprehensively assess their effects on health for a more informed understanding of the advantages and disadvantages of these products.
