Some evidence suggests that cigarette smokers are more likely to develop severe COVID-19 disease than non-smokers. Chronic smoke exposure appears to trigger the expansion of cell types in the respiratory tract that produce ACE2, the receptor for SARS-CoV-2. This observation provides a plausible hypothesis to explain why cigarette smokers might experience more severe COVID-19. A …
