The use of e-cigarettes, or vaping, causes serious damage to the lungs. After the novel coronavirus responsible for the respiratory disease COVID-19 emerged last year, there have been ongoing concerns about how vaping might impact risk of infection and severity of symptoms. Some evidence shows an increased risk of COVID-19 among those who vape. Research also shows a higher COVID-19 mortality rate in men compared to women, and men are more likely to vape than women. However, there is no evidence to link these two observations.
