Effects of tobacco cigarettes, e-cigarettes, and waterpipe smoking on endothelial function and clinical outcomes
Key result
Tobacco and e-cigarette use linked to impaired endothelial function, higher CVD risk, and severe COVID-19.
Why the study?
Despite declines in global tobacco use, e-cigarette and waterpipe use is emerging, with growing evidence that e-cigarettes are not harm-free and debate over whether they save smokers or generate new addicts.

Implication
Supports avoiding e-cigarettes as safe alternatives; challenges consensus but remains hypothesis-generating pending trials.
Key Points
- To review the effects of conventional tobacco cigarettes, e-cigarettes, waterpipes, and heat-not-burn products on endothelial function, molecular pathways, and cardiovascular disease risk.
- Synthesized findings from human and animal studies evaluating the vascular impact of tobacco cigarettes, waterpipes, and e-cigarettes.
- Assessed mechanistic disruptions across the proteome, transcriptome, epigenome, microbiome, and circadian rhythms.
- Reviewed current regulatory frameworks, advertising approaches, and potential links to COVID-19 symptom severity in the USA and Europe.
- Tobacco smoking, waterpipe use, and e-cigarette vaping all impair endothelial function, serving as an early indicator of subclinical atherosclerosis.
- Toxic constituents across these nicotine delivery systems induce adverse alterations in gene expression, epigenetic marks, and host microbiome composition.
- Evidence indicates e-cigarettes are not harm-free alternatives and, alongside traditional smoking, may exacerbate COVID-19 severity and cardiovascular disease progression.
