Smoking and COVID-19: what is the real situation?
Since late 2019, the world has been facing the consequences of the COVID-19 pandemic, a complex respiratory disease that has disrupted the lives of millions of people. This virus primarily affects the respiratory system, weakening lung function and causing serious complications.
Smokers whose lungs are already damaged by tobacco use and related health problems are at increased risk.
Interestingly, some studies have suggested that nicotine, the main component of tobacco, may have a protective effect against the severe symptoms of COVID-19.
But are such claims credible? Let’s take a look at the research and the latest data to better understand the link between smoking and COVID-19.
COVID-19 and smoking: do cigarettes reduce the risk of infection?
Unexpected clinical trials
At the start of the COVID-19 pandemic in late 2019, researchers began to investigate factors that could increase or decrease the risk of contracting the virus.
In some studies, smokers have been found to have lower seropositivity rates than the general population. This has led to speculation that nicotine may have a protective effect.
Hypothesis without foundation
Although the association between nicotine and COVID-19 has received a lot of attention, there is still no reliable evidence that smoking provides any protection.
Early studies had serious shortcomings, such as selection bias, errors in data interpretation and the exclusion of key factors such as pre-existing health conditions, access to health services and accuracy of testing from the analysis.
Some of these studies have already been retracted, so such claims should be treated with caution.
Smoking and COVID-19: increased risk in smokers
Worrying statistics in Lithuania
According to studies, smokers have a 40-50% higher risk of developing serious complications from COVID-19.
This includes a higher chance of hospital admission, artificial lung ventilation, intensive care unit treatment or even death. Some studies show that the risk of severe complications can be as high as 80% for smokers.
Smokers with comorbidities such as cardiovascular or respiratory diseases are particularly vulnerable.
These conditions, which are often exacerbated by tobacco use, significantly increase the likelihood of adverse outcomes from COVID-19.

Tobacco: an admitted killer
In Lithuania, tobacco use remains one of the leading causes of preventable deaths.
Smoking kills around 8,000 people every year and cigarettes contain more than 4,000 harmful substances, including carcinogens and toxins.
These substances contribute to many respiratory and heart diseases, such as:
- Chronic obstructive pulmonary disease (COPD)
- Arterial hypertension
- Bronchitis and recurrent infections
- Cardiovascular diseases
- Lung and other cancers
As well as impairing long-term health, these diseases increase the risk of serious complications from infectious diseases, including COVID-19.
Smoking habits and virus transmission
Smoking habits significantly increase the risk of spreading COVID-19.
Smokers frequently touch their faces, adjust their masks, and touch shared objects such as lighters or cigarette packets.
In addition, frequent coughing spreads respiratory droplets, which increases the chance of transmitting the virus to others.
Fight severe COVID-19 by quitting smoking
Tobacco and COVID-19 are a dangerous combination. Quitting smoking is one of the most effective ways to reduce the risk of contracting the virus and the severe form of the disease.
Taking action now is one of the best decisions you can make for your health.
