Smoking and COVID-19: What’s the truth?

Since the end of 2019, the world has been battling the complex and devastating COVID-19 pandemic, a respiratory illness that has disrupted millions of lives. The virus primarily targets the respiratory system, impairing lung function and causing severe complications. Smokers, whose lungs are already weakened by tobacco use and its associated diseases, are particularly vulnerable.

Some studies have even suggested that nicotine, a key component of tobacco, might offer a form of protection against severe COVID-19 symptoms. But how credible are these claims? Let’s explore the scientific literature and emerging research to understand the connection between smoking and COVID-19.

COVID-19 and smoking: Do cigarettes lower the risk of infection?

Surprising clinical studies

During the initial outbreak of SARS-CoV-2 in late 2019, researchers investigated factors that might predispose or protect individuals against the virus. Some studies suggested that smokers had a lower seropositivity rate compared to the general population, sparking speculation about nicotine’s potential protective effect.

A hypothesis that lacks evidence

While the relationship between nicotine and COVID-19 remains an area of interest, there is no conclusive evidence to support the theory that smoking provides protection. Initial studies faced methodological concerns, including selection bias, data interpretation flaws, and uncontrolled variables like comorbidities, healthcare access, and testing sensitivity.

Several of these studies have since been retracted, highlighting the need for caution when interpreting such findings.

Smoking and COVID-19: Additional risks for smokers

Alarming statistics from canada

According to studies published, smokers have a 40–50% increased risk of developing severe COVID-19. This includes a higher likelihood of hospitalization, requiring mechanical ventilation, admission to intensive care, or even death. Some research suggests that the risk for smokers may rise as high as 80% for severe complications.

Smokers with pre-existing conditions, such as cardiovascular or respiratory diseases, face compounded risks. These conditions, exacerbated by tobacco use, significantly increase the likelihood of poor outcomes in COVID-19 cases.

Tobacco: A recognized killer

In Canada, tobacco use remains the leading cause of preventable deaths, accounting for over 48,000 fatalities annually. Cigarettes contain more than 4,000 harmful substances, including carcinogens and toxins, which cause a range of cardiorespiratory diseases, such as:

  • Chronic obstructive pulmonary disease (COPD)
  • Hypertension
  • Bronchitis and recurrent infections
  • Cardiovascular disease
  • Lung and other cancers

These comorbidities not only compromise long-term health but also worsen the prognosis for COVID-19 infections.

Smoking habits and virus transmission

The habits associated with smoking further increase the risk of COVID-19 transmission. Smokers frequently touch their faces, adjust masks, and handle shared items like lighters or cigarette packs. Additionally, a smoker’s persistent cough can spread respiratory droplets, facilitating the virus’s spread in their immediate environment.

Combat 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 your risk of contracting the virus and experiencing severe illness. Taking steps to quit now is the best action you can take to protect your overall health.
