E-cigarettes deliver cancer-causing chemicals that enter the body of teens who vape or smoke them, a new study has found.
The variety of vaping chemicals popular among teenagers are fruity flavors, which appear to be the most deadly, scientists reported Monday.
They stated teens who attempt vaping are poisoning themselves with much of the very same chemicals that make traditional cigarettes so dangerous.
Tests on teenagers show that those who smoke tobacco-based cigarettes have the highest levels of these chemicals in their bodies.
But researchers were surprised to find that those who vape e-cigarettes also have far greater levels of the cancer-causing chemicals than nonsmokers.
The study was carried out by an independent research group at the University of California, San Francisco.
“The presence of harmful ingredients in e-cigarette vapor has been established; we can now say that these chemicals are found in the body of human adolescents who use these products,” they composed in their report, released in the journal Pediatrics.
E-cigarettes utilize a device that provides fluid laced with nicotine and tastes, producing a smoke-like haze.
They’re promoted as a “safer” method to use over tobacco, with e-cigarette use typically called vaping.
A lot of traditional cigarette smokers use vaping as a method to stop tobacco smoking.
E-cigarettes found to be dangerous for teens who vape
However, public health groups, the cosmetic surgeon general’s office, and the Centers for Disease Control and Prevention fret about evidence that vaping can get teens addicted to nicotine, and will lead them to cigarette smoking cigarettes.
Many research studies support the theory that kids who vape are more likely to go on to utilize other tobacco items.
However, there hasn’t been much difficult proof about how straight dangerous e-cigarettes are.
Monday’s study reveals vaping provides harmful chemicals and possibly damaging chemicals.
The chemicals are not listed on the active ingredients of the vaping liquid.
They’re found under the catch-all description of “flavorings” which allows manufacturers to “side-step” regulations, the scientists said.
Dr. Mark Rubinstein, of UCSF’s Division of Adolescent Medicine, and colleagues evaluated 67 teens who vape and compared them to 16 teenagers who both vape and smoke tobacco cigarettes and to 20 teens who do not utilize either kind of cigarette.
They tested their urine and saliva and asked questions about cigarette use.
Dangerous levels of toxic chemicals found
Those who used both types of cigarette had significantly higher levels of unsafe chemicals, including acrylonitrile, acrolein, propylene oxide, acrylamide and crotonaldehyde, the group reported.
And those who inhale just e-cigarettes had much greater levels than those who used neither product.
“Among our e-cigarette–only participants, the use of fruit-flavored products produced significantly higher levels of the metabolites of acrylonitrile,” they wrote.
“Acrylonitrile is a highly poisonous compound used widely in the manufacture of plastics, adhesives and synthetic rubber,” the National Center for Biotechnology Information says on its website.
Acrolein “is toxic to humans following inhalation, oral or dermal direct exposure,” the Environmental Protection Agency said.
Some studies reveal it can play a part in producing lung cancer, although the EPA noted that there is not adequate information to reveal whether it causes cancer in individuals.
Propylene oxide and crotonaldehyde are likely carcinogens, the EPA states, while acrylamide’s role in causing cancer is more questionable.
Other groups have actually found other potentially cancer-causing chemicals in e-cigarette vapor, including diacetyl, the chemical blamed for triggering “Popcorn lung” in employees at microwave popcorn product packaging plants.
Teens who vape are truning to vaping more frequently than they are smoking cigarettes, the CDC says.
The current report on teen smoking shows 20 percent of high school trainees have used a minimum of one tobacco product just recently– primarily e-cigarettes.
In 2016, 11 percent of high school students had actually utilized an e-cigarette in the previous 30 days at the time of the study– the CDC’s definition of present usage.
“Teenagers need to be warned that 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,” Rubinstein stated in a declaration about the disturbing findings.
“Teenagers should be inhaling air, not products with toxins in them.”
