Another scientific study has shown that the widespread use of flavorins in e-cigarette sidons increases the risk of lung damage and dysfunction. Researchers from the University of Rochester Medical Center said nearly 40 chemicals were found in seven JUUL flavors using mass spectrometry, including volatile organic compounds and hydrocarbons.
During the study, the researchers also exposed human lung tissue to e-cigarette smoke from JUUL flavor, which contains a mixture of flavoring agents and nicotine base fluids. The researchers said epithelial cells experienced “degradation” of integrity and inflammation, which can turn into lung disease and “acute lung damage.”
In addition, the team found that the lung tissue DNA exposed to e-cigarettes was damaged and could worsen toward cancer. Although JUUL recently stopped selling most flavorings in the U.S., it still sells menthol versions. The study found that menthol, like other flavors, carries a risk of lung health.
