According to the World Health Organization (WHO), one hundred million deaths were caused by tobacco smoking in the 20th century, and if current trends continue, there will be up to one billion deaths attributed to tobacco use in the 21st century. There are more than one billion smokers in the world, and globally the use of tobacco products is increasing, with the epidemic shifting to the developing world.
A Scientific Research by University of British Columbia scientists suggest that giving up smoking could lessen the chance that an infection with SARS-CoV-2 coronavirus will lead to severe COVID-19 disease. Their studies found that the lung cells of people who are current cigarette smokers, and individuals with chronic obstructive pulmonary disease (COPD), have increased levels of the angiotensin converting enzyme II (ACE-2) receptor that the SARS-CoV-2 virus uses to gain entry into host cells and cause infection.
It also found that patients with COPD and people who are still smoking have higher levels of ACE-2 in their airways, which might put them at an increased risk of developing severe COVID-19 infections.
