There is no research to support a connection between vaping and COVID-19.

The Food and Drug Administration (FDA) has stated, “E-cigarette use can expose the lungs to toxic chemicals, but whether those exposures increase the risk of COVID-19 is not known.” The FDA removed vaping from its risk statement to reference smoking only. “Cigarette smoking causes heart and lung diseases, suppresses the immune system, and increases the risk of respiratory infections,” FDA spokeswoman Alison Hunt said. “People who smoke cigarettes may be at increased risk from Covid-19, and may have worse outcomes from Covid-19.”

The Science Media Research Center released statements further clarifying what is known about vaping and COVID-19. “There is no evidence that vaping increases the risk of infection or progression to severe conditions of COVID-19. However, vapers with a long previous smoking history could exhibit conditions seen in vulnerable patients. However, this would not be an effect of vaping but of previous smoking. Since completely switching from smoking to vaping improves cardiovascular and respiratory conditions, smokers who switch to vaping might be expected to have a better prognosis if infected by COVID-19,” said Dr. Caitlyn Notley. “E-cigarettes are the most popular consumer option for stop smoking support, and they are effective. People should be encouraged to switch to vaping rather than continuing to smoke tobacco.”

The World Health Organization (WHO) released their statement “Tobacco use and COVID-19”, outlining the increased risk associated with smoking. The statement does not identify vaping as a risk factor.

A new study published in the British Medical Journal, “Risk of severe COVID-19 disease with ACE inhibitors and angiotensin receptor blockers: cohort study including 8.3 million people,” found decreased risk of both COVID-19 disease and intensive care admission in smokers. This data has been replicated by more than 720 studies globally.

Currently, some scientists believe that nicotine may reduce COVID-19 vulnerability, however no study has conclusively proven why statistically smokers are at decreased risk for COVID-19.
