Long-term health risks of e-cigarettes after smoking cessation

A study published in Nature Medicine in June 2026 examined the health effects of e-cigarettes after smoking cessation. Research based on data from a nationwide cohort suggests that using electronic cigarettes after quitting traditional smoking may reduce the benefits of cessation in lowering lung cancer risk and mortality. Scientists found that e-cigarettes may not provide the expected health benefits to former smokers. The results highlight the need for further research to develop evidence-based recommendations for clinical practice. The study emphasizes the importance of comprehensive understanding of the long-term effects of e-cigarettes on health.
