The more packets of cigarettes you smoke over your lifetime, the higher your risk may be of being hospitalised or dying from COVID-19, according to US research. Previously evidence to link smoking to COVID-19 risk had been limited and often contradictory but this study found that the cumulative exposure to cigarette smoke was an independent risk factor for hospital admission and death from COVID-19.
