Vaping May Raise Susceptibility To COVID-19, Study Warns

A recent study from the University of California, Riverside suggests that vaping may increase susceptibility to SARS-CoV-2, the virus that causes COVID-19. Researchers found that ingredients in vaping liquid, such as propylene glycol and vegetable glycerin, along with nicotine, could enhance susceptibility to the virus. However, the addition of benzoic acid to e-liquids can prevent this increased susceptibility. The study used airway stem cells to create a 3D model of human bronchial epithelium and observed increased activity of ACE2 and TMPRSS2, both necessary for the virus to infect cells. Researchers advise caution in vaping products and encourage users to quit or choose e-liquids with acidic pH or benzoic acid.
