Berry-flavored vaping products may weaken the lungs’ natural defense mechanisms, reducing the body’s ability to fight infections.
This is what emerges from a study in which the effects of flavored electronic cigarettes were compared to those of unflavored electronic cigarettes.
Research has already shown that any form of vaping can be harmful. However, the results of the present study suggest, like many other studies, that flavorings added to vaping solutions can aggravate the risks.
Following a series of cases of lung damage in adolescents in 2019, Ajitha Thanabalasuriar, assistant professor in the Department of Pharmacology and Therapeutics at theMcGill Universityin collaboration with Erika I think, from theUniversity of Saskatchewanhad the idea of exhibiting mouse to the steam of electronic cigarette for several days and to use a technique ofimagery live in order to observe temps real immune cells in their lungs.
Published in the journal PNAS, the study shows that certain chemicals in berry-flavored vapes paralyze immune cells in the lungs, whose role is to eliminate harmful particles, making the body more vulnerable to respiratory infections. . On the other hand, unflavored vapes did not have this effect.
“We must be careful with the flavors we add to vaping devices, because they can be harmful. This is the message to remember. Manufacturers market certain vaping items with the aim of attracting young people. Packaging and packaging “The products themselves are attractive, often very colorful. If our young people continue to inhale these flavored vapors, it could be disastrous for the future,” she says.
The researcher explains that it remains to find which compounds are damaging to immune cells in berry-flavored e-cigarettes and to confirm whether the effects observed in mice are reproducible in humans.
The study was funded by the Canadian Institutes of Health Research, Initiative interdisciplinary in infection and immunityUniversité McGill and the allocation granted by the Canada Research Chairs Program. The article “Alveolar macrophage function is impaired following inhalation of berry e-cigarette vapor”, by Ajitha Thanabalasuriar, Erika Penz et al., was published in the journal PNAS.
