E-cigarettes and vaping, new spotlight on smoking as an old cardiovascular risk factor?

Abstract

Smoking is one of the leading causes of chronic non-communicable diseases and a significant risk factor for cardiovascular and respiratory diseases. While global tobacco consumption has decreased over the past two decades, the use of e‑cigarettes and water pipes (shisha) has surged at an alarming rate, particularly among younger individuals. E‑cigarettes do not offer a completely risk-free alternative to traditional cigarettes, as the vast array of flavors and ease of use contribute to a growing number of dependent users. Furthermore, they are not necessarily effective in overcoming nicotine addiction. This contribution provides an overview of the cardiovascular health impacts associated with shisha smoking and e‑cigarette vaping, with a particular emphasis on the detrimental effects on endothelial function. The harmful biological effects of the toxic substances in these products, especially oxidative stress and inflammatory responses, are also discussed. Finally, the current state of recommendations, legal regulations, and commercial advertising are summarized.
