Study Finds E-Cigarettes May Be As Harmful As Smoking Tobacco

Since e-cigarettes came on the market in 2004, there has been much debate on their safety and health effects on users. Concerns regarding e-cigarettes prompted the U.S. Food and Drug Administration to tighten regulations on e-cigarettes in 2016.

"Some people use e-cigarettes heavily because they think there is no harm," Karteek Kadimisetty, a postdoctoral researcher at UConn's chemistry department, said in a press release. "We wanted to see exactly what might be happening to DNA, and we had the resources in our lab to do that."

The team at UConn created a low-cost 3D-printed electro-optical screening device that quickly detects carcinogenic chemicals that may cause DNA damage from e-cigarette vapor. Cellular mutations caused by DNA damage can cause cancer.

Using the device, researchers found e-cigarettes containing a nicotine-based liquid are potentially as harmful as unfiltered tobacco cigarettes in causing DNA damage.

The study also found that the vapor from non-nicotine e-cigarettes can cause as much DNA damage as filtered cigarettes due to the chemical additives found in e-cigarette vapors.

According to Kadimisetty, the amount of DNA damage caused by e-cigarettes depends on the amount of vapor a person inhales, other additives present and whether nicotine or non-nicotine liquid is used.
