Smoking and COVID-19

What You Should Know About Smoking and COVID-19

Coronaviruses are a large family of viruses that can cause illness in people. Human coronaviruses are not new — they are common throughout the world and typically cause mild to moderate illnesses. The novel coronavirus, or COVID-19, is a respiratory virus first identified in December 2019. COVID-19 is not the most contagious of the coronavirus family, but what makes it so dangerous is that no one is immune. SARS (severe acute respiratory syndrome) and MERS (Middle East respiratory syndrome) are much more contagious but can be controlled through vaccinations.

As with any lung illness, smoking increases the risk of negative health effects, including severe illness and death, among those infected with COVID-19. Current and former smokers are at greater risk for developing severe illness from COVID-19.  Preliminary research suggests that smokers infected with COVID-19 are nearly 1.5 times more likely to have severe symptoms and 2.5 times more likely to be admitted to the ICU, need mechanical ventilation, or die compared to non-smokers.

New research suggests that current smokers may also be at a greater risk of contracting COVID-19. In a recent study, researchers found that cells exposed to cigarette smoke were two to three times more likely to become infected with COVID-19 than cells not exposed to cigarette smoke. Smoking blocks the immune response in the body’s cells, which makes people who smoke more susceptible to disease.

To help protect yourself, the best thing you can do for your health is to stop smoking if you currently smoke, and if you used to smoke, do not start again. If you are interested in quitting smoking, visit our Courage to Quit page.

Vaping and COVID-19

New research suggests vaping affects lung health, decreases the body’s ability to respond to infection, and increases the severity of lung diseases. E-cigarette users are likely at an increased risk of developing more severe complications if they contract COVID-19 than people who do not vape. Recent research suggests young adults who vape are five times more likely to receive a positive COVID-19 diagnosis compared to their non-vaping peers. While research into e-cigarettes and their effects on lung health continues, the safest option to prevent serious risks is to stop use of all e-cigarettes.

Thinking About Quitting?

In addition to following social distancing guidelines and other recommendations to reduce the likelihood of contracting the virus, smokers and e-cigarette users should take additional steps to reduce their chances of developing severe symptoms if they get sick. Now is a great time to consider quitting smoking and other forms of tobacco use, including e-cigarettes. If you are a smoker, quitting smoking is one of the most important things you can do to protect your health and prevent severe outcomes that may result from COVID-19.

Quit Tips While at Home

1. Prepare your environment. Use this time to get rid of any reminders of smoking or vaping around your home. Wash your clothes, get rid of any smoking or vaping supplies, and dispose of all your cigarettes or vapes. Keeping cigarettes, vapes, or lighters “just in case” undermines your self-confidence.
2. Find support. Have someone you can call or reach out to when you have the urge to smoke or vape. Share your decision to quit with someone else who can hold you accountable.
3. Stay motivated. Make a list of reasons to quit and keep the list where you can see it. Revisit these reasons when you have the urge to smoke or vape.
4. Get moving. Plan ahead for ways to stay active at home when a craving hits. Find free workout videos online. Do yoga, lunges or push-ups in your home. Staying active will keep your mind off of smoking or vaping until the craving passes.
5. Reward yourself for not smoking or vaping. Set short and long term goals, and reward yourself for each milestone you reach. Making a “contract” with yourself or a friend can help you stay resolved.
6. Don’t be discouraged. Many former smokers tried to stop several times before they finally succeeded. If you give in to a craving, don’t let it get you down. Examine what went wrong, learn from what happened and quit again!
