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

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.

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.

Vaping delivers potentially cancerous chemicals found in tobacco cigarettes to teens, even if a e-cigarette has no nicotine, said a new study released on Monday by researchers at the University of California, San Francisco.

That risk level was the same for those using both e-cigs and tobacco.

Apparently, the "flavor" of the e-cigarette cartridge matters. E-cigarettes are more an more used by teenagers because of the massive marketing campaigns that promote them as safe alternatives to classic smoking.

Hess said there are countless other studies that prove vaping is 95 percent safer than smoking traditional cigarettes. "But when they're heated to the high temperatures required for vaporization, they can produce toxic substances that are potentially carcinogenic", he said. Some of the chemicals turned up even when teens used non-nicotine products like fruit flavored e-cigarettes.

The National Center for Biotechnology Information said acrylonitrile is a highly poisonous compound used widely in the manufacture of plastics, adhesives, and synthetic rubber.

Last week, a study of almost 70,000 people found that daily e-cigarette use can double the risk for heart attack.

Acrolein "is toxic to humans following inhalation, oral or dermal exposure", the Environmental Protection Agency says.

Propylene oxide and crotonaldeyde are probable carcinogens, the EPA says, while acrylamide's role in causing cancer is more controversial. However, the Centers for Disease Control and Prevention warns there is enough evidence that vaping can be harmful to teens.

Mark Rubinstein, the lead author of the study, said "the vapor produced by e-cigarettes is not harmless water vapor, but actually contains some of the same toxic chemicals found in smoke from traditional cigarettes".

In 2016, more than two million U.S. 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 USA adults.

The compounds examined in the study include acrylonitrile, acrolein, propylene oxide, acrylamide and crotonaldehyde, all of which have been associated with increased cancer-risk in previous studies.
