Vaping pen and cigarettes

Current and former smokers have a higher severity of COVID-19, recent studies indicate.

COVID-19 patients who smoke, vape, and are former smokers make up a higher percentage among those who have had severe cases and needed ICU support and mechanical ventilation. They also make up a higher percentage of those who have died. Smokers were 1.4 times more likely to have severe cases of COVID-19 and approximately 2.4 times more likely to be admitted to an ICU, need mechanical ventilation, or die, compared to nonsmokers.

Smoking inflames the lungs and suppresses immune function. Smoking is a known risk factor for influenza, and long-term smoking can lead to chronic obstructive pulmonary disease (COPD), a condition that also makes people more susceptible to infection.

While there is clear scientific evidence for the risk of viral infections and cigarette smoking, there are few studies focused on vaping. However, the studies that have been done on vaping point to similar inflammation issues connected to respiratory infections, especially in those who have previously never smoked.

Those who smoke or have smoked in the past should take special precautions to prevent contracting COVID-19. For those who do not smoke, now is not the time to start. You may place yourself at a higher risk of a severe or fatal case of COVID-19 if you do contract the illness.
