Chemical and liquid flavorings used in electronic cigarettes and vaping devices may be harmful to white blood cells called monocytes, according to report in Frontiers in Physiology. Monocytes help to fight infection, remove damaged tissues, destroy cancer cells, and regulate immunity.
Researchers at the University of Rochester Medical Center in New York found that flavorings in e-cigarettes may be safe to consume in general, but they can cause significant inflammation and damage to monocytes cells when they’re inhaled. The study also suggests that the toxic effects of the flavorings, which include cinnamon, vanilla, buttery flavors, and others, are much worse when flavors are combined.
These findings add to the mounting evidence that e-cigarettes – even those that do not contain nicotine – may be harmful and should not be marketed to young people.
