LEXINGTON, Ky. (Aug. 10, 2020) — We now know more about the risks of smoking and COVID-19, though studies are still ongoing. Early reports found people sickened with the Coronavirus-19 (COVID-19) infection had more severe illness if they smoked.
A recent review of five published studies supports this finding: Persons who smoke have double the risk of severe infection compared to those who do not smoke.
We know that smoking and vaping:
- Cause damage to our lung’s natural defenses against invasive bacteria and viruses.
- Expose users to chemicals that weaken the immune system and limit the body’s ability to fight off infection.
- Increase the risk of heart and lung disease, conditions which also increase the risk of severe COVID-19 illness.
The actions of putting hand to mouth in smoking and vaping can increase the risk of exposure to bacteria and viruses. Smoking one pack a day results in around 300 hand-mouth contacts. Smoking and vaping also decrease mask-wearing time, limiting protection from virus exposure.
Support and medications, such as nicotine replacement products, can make the process of quitting tobacco products easier and success more likely as only four to five out of 100 people who try to quit on their own succeed. Talk to your healthcare provider, call the Tobacco Quitline (1-800-QUITNOW) or visit www.smokefree.gov for help.
