FAQs – Coronavirus (COVID-19) and Smoking

We answer commonly asked questions about COVID-19 and smoking.

People who smoke are generally at higher risk of respiratory tract infections, like chest infections, and there is growing evidence that people who smoke may be at higher risk of COVID-19 and its complications. People with poor lung health and other conditions like cardiovascular disease and cancer (which can be caused by smoking) are also at higher risk of complications if they do become infected with the virus. It’s not clear how long a person needs to stop smoking to reduce their risk of these complications. It’s important to remember stopping smoking has many health benefits, even beyond a link with COVID-19, so it’s always a good time to quit. Quitline continues to be available to offer support.

Q. Are people who smoke at more risk of COVID-19?

While it's not certain that people who smoke are more likely to get COVID-19, we know that they are at a higher risk of getting respiratory infections in general. This means that it’s more likely than not that people who smoke have a higher risk of getting COVID-19 compared to people who don’t smoke. 

Also, the hand-to-mouth action of smoking and e-cigarette use means that people who smoke may be more vulnerable to COVID-19, as they are touching their face and mouth more often.

It’s not known for sure, but it’s also possible the vapour from e-cigarettes may be able to spread the virus (either in the air or as it settles on surfaces).

Sharing any type of tobacco or smoking product (for example, cigarettes, e-cigarettes or shisha/waterpipes) can also increase the risk of spreading COVID-19. 

Q. Are people who smoke more likely to have severe complications if they do get COVID-19?

There is growing evidence to suggest that people who smoke are likely to be more severely impacted by COVID-19, because smoking damages the lungs so that they don’t work as well. For example, lungs naturally produce mucus, but people who smoke have more and thicker mucus that is hard to clean out of the lungs. This mucus clogs the lungs and is prone to becoming infected. Smoking also affects the immune system, making it harder to fight infection.

There is also evidence that people with other health conditions like cardiovascular disease and cancer are more likely to experience severe complications of COVID-19. Smoking increases the risk of many of these conditions.

Q. What if I previously smoked? Am I still at more risk of COVID-19?

It’s not currently known if people who have previously smoked have a higher risk of getting COVID-19 compared to people who have never smoked. People who smoke are at increased risk of lung infections in general, but the lungs do heal relatively rapidly when people stop smoking. It’s not yet known how long is long enough to reduce the risk to the same as someone who has never smoked. 

If you previously smoked and are now quit, it’s likely you’ll have a lower risk of severe complications (if you were infected with the virus) than you would have if you were still smoking.

Q. For how long do people have to stop smoking to reduce their risk of COVID-19 and possible complications?

This is not currently known for COVID-19 specifically, but it’s well-understood that stopping smoking improves lung health within a few months. Rates of lung infections like bronchitis and pneumonia also decrease.

If you’re still trying to quit (or even if you have recently quit), there are other things you can do to protect yourself and others at this time. Talk to your doctor or pharmacist about getting the flu shot for both you and your family. Also avoid exposing people around you to second hand smoke.

Q. Is it still safe to start, or continue to use, nicotine replacement therapy and other stop smoking medications?

For people who smoke, stop smoking medications like nicotine replacement therapy (NRT) can help to reduce cravings and manage withdrawal symptoms.  When combined with tailored support from Quitline, these medications give people the best chance of successfully quitting.

There is no evidence that COVID-19 has an impact on the safety and effectiveness of these medications. If you are already using these medications, it is safe to continue to do so, as instructed by your doctor. If you are thinking about starting these medications, it is best to first speak with a Quitline counsellor (13 7848) or your doctor.

As with any medication that means you need to touch your lips or mouth to take it, remember to wash your hands before you use any type of NRT or other stop smoking medication, just as you would before handling food.

Q. How can I tell the difference between nicotine withdrawal symptoms and COVID-19 symptoms?

People who have recently stopped smoking may experience nicotine withdrawal symptoms, which can include cravings, irritability, and difficulty concentrating. These symptoms are usually temporary and disappear after about 2 to 4 weeks. 

Less common symptoms of nicotine withdrawal might include a cough and sore throat, which are usually also temporary. These withdrawal symptoms may be confused with the symptoms of COVID-19. It’s important to remember that fever isn’t a symptom of nicotine withdrawal.  

It’s best to speak to your doctor if you are worried you may have COVID-19.
