Association between long-term smoking cessation and COVID-19 outcomes: Findings from a nationwide cross-sectional online survey in China
Long-term smoking cessation was not associated with an elevated risk of COVID-19-related pneumonia compared to never smokers, whereas ex-smokers (<10 years) and current smokers remained high-risk groups. These findings support the potential benefits of sustained cessation, although further longitudinal studies are needed to confirm and extend these findings.
