Users of E-Cigarettes Are Inhaling Harmful Chemicals

In the case of e-cigarettes, the ingredients listed are not all that customers are consuming. Yale researchers discovered that chemical reactions in flavored liquids of the popular Juul e-cigarette create unexpected chemicals that may irritate customers’ airways.

The scientists focused on acetals, which are chemicals that type when the common flavoring vanillin interacts with alcohols that carry the flavors and nicotine in e-cigarettes. Led by the lab of Zimmerman, professor of environmental engineering and chemical at Yale, the research was published July 30.

Regardless of the popularity of Juul, little is known about the composition of its aerosol (generally known as “vapor”). The scientists used a “vaping machine” custom-built in Zimmerman’s lab to research the chemical makeup of various flavors of the Juul refill cartridges, together with “Crème Brulée,” “Fruit Medley,” and “Cool Cucumber.”

“We have been able to detect these acetals both in ‘Crème Brulée’ e-liquid as well as in the generated from it,” mentioned lead author Hanno Erythropel, including that, is the first study of the presence of glycerol acetals in e-cigarette aerosol. Erythropel, an associate analysis scientist in Zimmerman’s lab, additionally noted that 60%-70% of the acetals transferred from the liquid to the vapor.

“Folks typically assume that these e-liquids are a closing product once they’re mixed,” Erythropel stated. “However, the reactions create new molecules within the e-liquids, and it doesn’t just occur in e-liquids from small vape retailers, but in addition in those from the biggest producers within the U.S.”
