Shocking Study: E-Cigarette Vapor Kills 85 % of the Cells in Your Mouth


Smoking e-cigarettes may not be much safer than tobacco when it comes to oral health, a new study suggests. People claim that EC can reduce the harm which regular cigarettes are causing. But this theory has many holes in it. According to the Centers for Disease Control and Prevention (CDC), between 2011-2012, e-cigarette use more than doubled among 15 and 19 age students in the United States, and in 2014, more than a fifth of adults who currently smoke reported also using e-cigarettes.

What Are E-Cigarettes?

E-cigarettes are battery-operated electronic devices that provide a way to get nicotine. Nicotine is an addictive drug that is naturally found in tobacco. E-cigarettes also allow nicotine to be inhaled, but they work by heating a liquid cartridge containing nicotine, flavors, and other chemicals into a vapor.

New Study Conducted by Dr. Shen Hu

A number of studies have shown that electronic cigarettes are not as harmful as the conventional cigarettes. New researchers found e-cigarettes contain toxic substances and nano-particles that could kill the top layer of skin cells in the oral cavity behind teeth and gums.

The researchers – led by Dr. Shen Hu, an associate professor of oral biology at the University of California-Los Angeles (UCLA) – came to their conclusion by analyzing the effects of e-cigarette vapor on cell cultures in laboratory tests.

How it Effects Our Oral Health

Inhaling heated chemicals, including the e-liquid ingredients nicotine, couldn’t possibly be good for you.

Vapours contain toxic substances and particles which damage skin cells.
Exposure reduced body’s natural defences of the antioxidant glutathione.
Scientists say it could lead to increased risk of oral disease like cancer.


“On assessing the effects of e-cigarette vapor on oral cavity cell cultures, the researchers found that the vapor reduced levels of glutathione within the cells, which is an important antioxidant that protects them from damage. As a result, the e-cigarette vapor destroyed around 85 percent of the cells.”

The substance directly kills airway cells and weakens the immune system, researchers found.
