A study by chemists at the University of Connecticut offers new evidence that electronic cigarettes or e-cigarettes are potentially as harmful as tobacco cigarettes.
Using a new low-cost, 3-D printed testing device, UConn researchers found that e-cigarettes loaded with a nicotine-based liquid are potentially as harmful as unfiltered cigarettes when it comes to causing DNA damage.
The researchers also found that vapor from non-nicotine e-cigarettes caused as much DNA damage as filtered cigarettes, possibly due to the many chemical additives present in e-cigarette vapors. Cellular mutations caused by DNA damage can lead to cancer.
The findings appear in the journal ACS Sensors.
How much DNA damage e-cigarettes cause depends on the amount of vapor the user inhales, the other additives present, whether nicotine or non-nicotine liquid is used, and other factors, says Karteek Kadimisetty, a postdoctoral researcher in UConn's chemistry department and the study's lead author.
But one finding was clear.
"From the results of our study, we can conclude that e-cigarettes have as much potential to cause DNA damage as unfiltered regular cigarettes," Kadimisetty says.
