Recent Study Suggests That Some Vape Flavour Additives Are Toxic

Titled, “In Vitro And In Vivo Cardiac Toxicity Of Flavored Electronic Nicotine Delivery Systems,” the current aimed to determine the impact of flavouring chemicals on heart health, by exposing heart cells from mice to flavour additives in a lab environment.

“The flavored electronic nicotine delivery systems widely popular among teens and young adults are not harm-free,” said lead study author Dr. Sami Noujaim in a university release. “Altogether, our findings in the cells and mice indicate that vaping does interfere with the normal functioning of the heart and can potentially lead to cardiac rhythm disturbances.”

More specifically, reported the study, vanillin aldehyde flavoured e-liquids reduced the hERG current in transfected human embryonic kidney cells, while in mice, the inhalation of this flavour additive increased sympathetic predominance in heart rate variability measurements.

However, commenting on the study, best selling author and health expert, Hank Campbell explained that the conclusions derived from study are flawed. “A new paper claims that people vaping instead of smoking are putting their hearts at risk but their study does not show that. Instead, they mixed chemicals in Petri dishes with heart cells and used mice. Both of those are fine exploratory experiments but they are scientifically invalid to make the conclusions the authors make in their press release,” said Campbell.

“Mice are not little people. No drug can get into the approval cycle at the US Food and Drug Administration if it only studied them or cells in dishes,” he added. Moreover, explained Campbell, the HL-1 cells from mice and later the lab produced human cells, were inundated with levels of vaping chemicals that a human body could not get exposed to in 40,000 years.
