Juul E-Cigarettes Contain These Unexpected Chemicals

The U.S. Centers for Disease Control and Prevention (CDC) has marked e-cigarettes unsafe for kids, teens and people in mid-20s due to its impact on their brains. The nicotine and other substances used in the device have been linked to addiction and problems with attention, learning and mood. 

E-cigarettes have also been found containing unknown ingredients that can be harmful. Researchers from Yale University found that products from the company Juul have chemicals that could irritate the airways of users. 

The additional chemicals were found in the liquid vanillin that provides a vanilla flavoring. The chemicals, called acetals, appeared from the flavored liquid after it interacted with alcohols used in vapes to add nicotine and flavors. 

The study, published in the American Journal of Preventive Medicine, analyzed Juul e-cigarettes using a vaping machine built at Yale. 

“We were able to detect these acetals bothin ‘Crème Brulée’ e-liquid as well as in the generated from it,” Hanno Erythropel, lead study author and an associate research scientist at the university, said in a press release

He added their study provides the first information on the presence of acetals in e-cigarette aerosol. During tests, the chemicals were produced by Juul products when exposed to glycerol.

Acetals were also present in tested flavors that contained menthol. The chemicals came surprising for the team, according to Sven-Eric Jordt, study co-author from Duke University. 

Acetals have been banned in traditional cigarettes. However, manufacturers are allowed to mix the chemicals in e-cigarettes.

“People often assume that these e-liquids are a final product once they are mixed,” Erythropel said. “But the reactions create new molecules in the e-liquids, and it doesn’t just happen in e-liquids from small vape shops, but also in those from the biggest manufacturers in the U.S.”

The researchers hope their study would guide the government in creating new e-cigarette regulations to address the presence of unknown and potentially toxic compounds. They added the health effects of e-cigarette liquids should also get more attention from regulators. 

The CDC estimates there are more than three million people currently using e-cigarettes in the U.S.
