Menthol flavors have been linked to poorer lung function in e-cigarette users, researchers report in the journal Respiratory Research. This is probably because they produce more toxic microparticles when used compared to menthol liquids.

Using specially designed machines that closely mimic human breathing when vaping e-cigarettes, the research team was able to show that using e-cigarette liquids containing menthol produces more toxic microparticles than other flavors. A study of a group of e-cigarette smokers found that menthol vapers had lower respiratory rates and poorer lung function than those using non-menthol products.

Although the sale of traditional menthol cigarettes has been banned across Europe for years, the market for e-cigarettes is growing worldwide, with mint and menthol flavors popular with young people. However, menthol additives can be just as dangerous as vitamin E acetate, which has been linked to lung damage in e-cigarette users. Vitamin E acetate is a common additive in e-liquids that contain cannabinoids. It produces toxic small particles that penetrate the narrowest airways and mucous membranes of the lungs.

“Many people, especially teenagers, mistakenly believe that vaping electronic cigarettes is safe. But even nicotine-free e-liquids contain many compounds that can damage your lungs. Just because something is safe to eat doesn't mean it's safe to inhale,” said Prof. Dr. Kambez H. Benam from the University of Pittsburgh. He advises young adults who have never smoked to be aware of the risks: “Transition . . E-cigarettes can be a better and safer alternative for someone trying to quit smoking traditional tobacco products. However, it is important to fully understand the risks and benefits of e-cigarettes.
