E-cigarettes and the risk of contracting COVID-19: possible connection found
Scientists have found a possible relationship between e-cigarettes and COVID-19. However, only samples of JUUL™ nicotine e-liquid were used in the study.
Scientists have analyzed the relationship between tobacco use and SARS-CoV-2 infection. In the study, they’ve tested the hypothesis that e-liquids and aerosols with a high concentration of nicotine contribute to the infection of the coronavirus, allowing it better penetration into the respiratory tract.
The study was based on a comparative method. The laboratory looked at cell responses both to the aerosols themselves and to their individual components: propylene glycol (PG), vegetable glycerin (VG) and nicotine. These cells were also immersed in different environments to account for possible fluctuations in the indicators.
As a result of the study, scientists came to an ambiguous conclusion. E-liquids can affect lung function regardless of the presence of nicotine or the type of e-cigarettes. What’s more, some flavorings provide additional detrimental effects.
Such an effect of fumes can disrupt the functioning of pulmonary surfactant, a fluid that prevents the alveoli and bronchi from sticking together. This increases the risk of developing pulmonary dysfunction. The latter, in turn, is a favorable condition for the penetration of COVID-19 into the body or an additional risk factor for the patient.
Details of the research methods can be found in the report published by scientists. It is also worth noting that the US Food and Drug Administration banned the sale of both JUUL e-cigarettes and their cartridges on June 23rd this year.
