In 2018, Illinois PTA Convention delegates passed a resolution on Electronic Nicotine Delivery Systems (ENDS). The resolution followed years of tracking the data and science surrounding ENDS use by youth, and Illinois PTA continues to keep its members informed about new developments. Once again, e-cigarettes are in the news, with reports of pulmonary illnesses and even deaths, including one here in Illinois.
The investigations into the causes of the illnesses and deaths are ongoing, with THC (the active ingredient in marijuana) vaping juice and vitamin E acetate found in many of those THC cartridges sampled being one early area of focus. However, a recent study in the journal Radiologyindicates that vaping itself can damage lungs.
The study by researchers at the Perelman School of Medicine at the University of Pennsylvania performed MRI exams on 31 healthy, non-smoking adults between 18 and 35 before and after taking 16 three-second puffs on an e-cigarette containing only “vaping juice,” a mixture of water, glycerol, and propylene glycol, the latter two being used in vaping cartridges to keep additional chemicals such as nicotine or flavorings dissolved in the cartridge.
The results of the study showed that even in non-smoking, first-time vapers with no nicotine in the cartridge, the use of an e-cigarette resulted in poorer circulation, stiffer arteries, and less oxygen in the blood. As the study’s principal investigator, Felix Wehrli, put it, “The results of our study defeat the notion that e-cigarette vaping is harmless.” Although both chemicals used in the study, glycerol and ethylene glycol, are considered safe to eat, they may not be safe to inhale.
