E-cigarette vapors kill cells, UCLA study finds


Youth now use e-cigarettes more than any other tobacco product, giving rise to sharp concerns among parents, health practitioners and public health advocates. However, evaluating the risks of e-cigarette use has been challenging due to the lack of research – at least, until now. A new UCLA study provides information about the harmful effects of e-cigarettes.

Published in the PLOS One journal, the study found that the toxic substances contained in e-cigarettes could kill the top layer of skin cells in the oral cavity and increase the risk of oral disease.

The UCLA research team conducted its study on cultured cells, exposing them to machine-generated e-cigarette vapor for 24 hours. As a result of a decrease in an antioxidant (glutathione) and subsequent weakening of the oral cavity’s defense mechanism, 85 percent of the tested cells died.

The research team indicated that a human study could produce similar results, and is planning additional studies with UCLA School of Dentistry patients who have used e-cigarettes.

More information about the study is available at dentistry.ucla.edu.

The secretary of state officially validated the tobacco tax measure for the November ballot on June 30 and announced that it will be Proposition 56. This is the result of efforts by the Save Lives California coalition, a partnership of health care and other organizations including CDA, which worked to get this life-saving initiative on the Nov. 8 statewide ballot.

With the passing of Major League Baseball great Tony Gwynn from mouth cancer, CDA reminds dentists that there are many resources available to help their patients stop using tobacco and smokeless tobacco products. Though Gwynn's mouth cancer was never medically linked to the use of smokeless tobacco, he believed it was related to his cancer diagnosis. Experience shows that an oral cancer lesion, which often grows slowly and may be painless, can easily be overlooked by a patient who has "had this spot forever."
