An increasing number of studies show that smokers may be more vulnerable to coronavirus disease (COVID-19) because they are at increased risk of severe symptoms and complications. Less is known about the risk of COVID-19 associated with vaping, but vaping might also have harmful health effects.

Risks associated with smoking and vaping

Smoking can reduce lung capacity and weaken the immune system. Smokers are at increased risk of developing respiratory infections, such as the flu or bacterial pneumonia. Smoking is also known to be the main risk factor for chronic obstructive pulmonary disease (COPD). People who have COPD are more prone to infections that can aggravate the symptoms associated with their lung condition.

People who smoke and who contract COVID-19 are thought to be at increased risk of complications (hospitalization, admission to intensive care, ventilatory support, death).

As yet, few studies have been done on the risk of COVID-19 associated with vaping. However, an increasing number of studies show that vaping could have harmful effects on the lungs and immune system. To learn more about the health risks of vaping, go to the page Electronic cigarettes.

Risk of transmission of COVID-19

Smoking and vaping involve frequent hand-to-mouth contact and sometimes sharing of products in some social situations, which could increase the risk of transmission of the virus according to the World Health Organization.


The pandemic may cause people to smoke more because they feel stressed and anxious about the situation: afraid of getting infected, feeling helpless, financial worries, being isolated, etc. However, having less social contact with coworkers and friends who are smokers could help people quit smoking. The current context would help even more, for in addition to the many benefits that usually come with quitting smoking, it could minimize the risks associated with COVID-19.
