Smoking harms your lungs and respiratory tract. It also damages your immune system. This means that smokers are at higher risk for acute respiratory infections, which last longer and are more severe than non-smokers.

Quitting smoking will help you stay healthy and can also reduce the risk of serious health problems if you become infected with COVID-19.

Experts advise that the best thing a smoker can do for their current and future health is to quit and quit now.
