Vaping can cause significant harm to the lungs

Publications of Interest

New research carried out by Carolyn Baglole, PhD, and her team at the Research Institute of the MUHC affirms that vaping e-cigarettes can lead to significant lung damage. In a recent study, mice were exposed to mango-flavored JUUL (a popular brand of e-cigarette) at a low dose for four weeks. It was discovered that even at this low level of exposure, significant cellular and molecular changes to the lungs occurred. This habit, once considered a harmless tool to aid in smoking cessation, and a safe alternative to smoking, is evidently not as innocuous as originally believed.

Our results show that inhalation of the vapor generated by a popular brand of e-cigarette causes widespread changes inside the lungs, data that further highlights that these products are not inert and may lead to lung damage if used long term.

The use of e-cigarettes is on the rise, and we must wait to see if this type of research and the ensuing discoveries will help decrease the interest in this pass-time. There is still much to be learned about the effects of vaping on the body; the full effect of which may take a decade or more to reveal itself. It is evidently a topic of interest for the general public, as indicated by the number of general-interest articles published below.
