E-cigarettes produce cancer-causing chemicals in bodies of vapers

Tests on teenagers show that those who smoke tobacco-based cigarettes have the highest levels of these chemicals in their bodies, but those who vape e-cigarettes also have higher levels of the cancer-causing chemicals than nonsmokers, the team at the University of California, San Francisco, found.

"Although e-cigarette vapor may be less hazardous than tobacco smoke, our findings can be used to challenge the idea that e-cigarette vapor is safe, because numerous volatile organic compounds we identified are carcinogenic", Dr. Rubinstein and colleagues wrote in the conclusion.

While those who smoke regular cigarettes had the highest levels, the study said e-cigarettes also pose a significant risk, in part because they are often promoted as being safer despite containing numerous same toxic chemicals. He agrees that teens should not have access to e-cigarettes, but overall, he says the benefits outweigh the risks. According to Rubinstein, the toxicity of non-nicotine e-cigarettes is caused by the propylene glycol and glycerin used to preserve the flavors.

To assess the connection between teenage use of e-cigarettes and later established smoking in those who have previously tried cigarettes, the researchers analyzed data concerning adolescents aged between 12 and 17 years who had reported smoking one or more puffs of a cigarette but not more than 100 cigarettes in the Population Assessment of Tobacco and Health survey.

In 2016, more than two million United States middle and high school students used e-cigarettes in the past 30 days, including 4.3 percent of middle school students and 11.3 percent of high school students, compared with 3.2 percent of U.S. adults.

"We touch on vaping and electronic cigarettes and how electronic cigarettes also have some chemicals that have been found to cause cancer", Meza said. "Teenagers should be inhaling air, not products with toxins in them".

They're promoted as a safer way to use tobacco - e-cigarette use is called vaping - and as a way to quit smoking. If the user continues to smoke regular cigarettes each day along with e-cigarettes, the combined risk goes up five times.

Teens are vaping more often than they are smoking cigarettes, the CDC says.

The same CDC report found that only 2.2 percent of middle-schoolers and eight percent of high-schoolers had smoked traditional cigarettes in the past 30 days. But public health groups, the surgeon general's office, and the Centers for Disease Control and Prevention worry about evidence that vaping can get teens addicted to nicotine, and will lead them to smoking cigarettes.

Dr Rubinstein said: 'I do not think teens are aware of the risks.

GOING VAPE? More than a million adults use e-cigs to stop smoking - but is vaping safe?

"The way they advertise them is they have different flavors and different flashy packages so they look more like candy", Meza said.
