Early results of an experimental vaping study have shown significant lung injury from E-cigarette (eC) devices with nickel-chromium alloy heating elements and were published in the Journal of American Heart Association. Robert A. Kloner, MD, PhD, chief science officer for Huntington Medical Research Institutes (HMRI) and professor of Medicine at USC, and Michael Kleinman, PhD, professor of occupational and environmental medicine at the University of California, Irvine’s School of Medicine and member of the UCI Center for Occupational and Environmental Health, led the study which was designed to explore the effect of e-cigarette and other vaping product use on the cardiovascular system. While conducting experiments, researchers observed eC or vaping product use-associated lung injury (EVALI) immediately after switching from a vaping device with a stainless steel heating element, to one that used nickel-chromium alloy (NC). The findings were consistent, with or without the use of nicotine, vitamin E oil or tetrahydrocannabinol (THC), which have previously been thought to contribute to the life-threatening respiratory problem.
The study was funded in part by the National Institutes of Health. In addition to Kleinman and Kloner, several researchers participated in the study, including HMRI researchers Jianru Shi, Wangde Dai, Juan Carreno, Jesus Chavez, and Lifu Zhao; and UCI researchers Rebecca Johnson Arechavala, David Herman, Irene Hasen and Amanda Ting.
