With the concerns of COVID-19 and its potential for increased harm to smokers, MDQuit is compiling resources and information concerning smoking, vaping and COVID-19.

No peer-reviewed population-level studies have been conducted to determine the risk of infection associated with smoking.1  However, tobacco users may be vulnerable to being seriously infected by COVID-19 due to reduced lung capacity, and possible lung disease, which would greatly increase their risk of serious illness from the disease.1 Additionally, “the act of smoking means that fingers (and possibly contaminated cigarettes) are in contact with lips, which increases the possibility of transmission of virus from hand to mouth.”2

The damage caused to the cardiovascular and respiratory systems by tobacco use can lead to a higher risk for severe illness from COVID-19. A systematic review of five studies found that compared to non-smokers, smokers were 1.4 times more likely to have severe symptoms of COVID-19 and 2.4 times more likely to be admitted to an ICU, require mechanical ventilation, or die.3

Studies have shown that exposure to nicotine and other chemicals in e-cigarettes can damage lungs comparable to combustible cigarettes.4,5 Also, as with cigarettes, the hand-to-mouth action of e-cigarette use may increase risk of transmission of the virus. A population-based study led by researchers at Stanford University found that adolescent and young adult (aged 13–24 years) users of e-cigarettes and dual-users of e-cigarettes and cigarettes are at greater risk of COVID-19.6 

Individuals who used both e-cigarettes and cigarettes in the past 30 days were 4.7 times more likely to experience COVID-19-related symptoms.6 Those who had ever used e-cigarettes were 5 times more likely to be diagnosed with COVID-19.6 Ever-dual-users were 7 times more likely and past 30-day dual-users were 6.8 times more likely to be diagnosed with COVID-19.6 

Leading health authorities thus continue to recommend that tobacco users (cigarettes, e-cigarettes, cigars, hookah, and smokeless) try to quit.
