More teenagers than ever are exposed to second-hand spray cans from electronic cigarettes, a new study warns.

Researchers discovered that a third of high and high school students said they were exposed to vapes in 2018.

This is a 30 percent increase compared to the teenagers who reported exposure between 2015 and 2017.

E-cigarettes have been associated with an increased risk of lung diseases and possibly certain cancers, including oral cancer.

The team at the Dana-Farber Cancer Institute in Boston, Massachusetts, says that clean air laws and interventions to reduce juvenile vaping are urgently needed to reverse the trend.

E-cigarettes are devices, often like cigarettes, cigars, or pipes, designed to provide users with nicotine or related substances in the form of a vapor.

They contain a solution that is heated and converted into an aerosol, which is then inhaled.

E-cigarettes are the most widely used tobacco product among American teenagers.

The Surgeon General 2016 report showed that the use of e-cigarettes among young people had increased by 900 percent between 2011 and 2015.

"There is a rising trend of vape among young people in the US, including JUUL and pod-based e-cigarettes," Dr. told. Andy Tan, a researcher at the Center for Community Based Research at the Dana-Farber Cancer Institute, at DailyMail.com.

& # 39; We were concerned that some who did not use were exposed to second-hand aerosols. & # 39;

Proponents have promoted e-cigarettes as healthier, safer alternatives to traditional tobacco products.

But health experts say that many of the toxins in the product make them harmful.

This includes ultra-fine particles that can be inhaled deep into the lungs, flavors associated with a serious lung disease and an increased risk of oral cancer.

& # 39; Unlike claims in marketing and advertising, aerosols are not only water vapor, they contain harmful substances, & # 39; said Dr. Tan.

For the study, published in JAMA Network Open, the team analyzed data from the national youth tobacco survey from 2015 to 2018, which is being conducted by the Centers for Disease Control and Prevention.

Participants were asked how often in the last 30 days they had inhaled smoke in public places by someone using tobacco products or e-cigarettes.

Exposure to second-hand spray cans increased from around one in four teenagers between 2015 and 2017 to one in three in 2018.

The most significant increase occurred from 2017 to 2018, rising from 25.6 percent of secondary and secondary school students to 33.2 percent.

This is despite 16 states and more than 800 municipalities that have introduced or introduced restrictive laws use of e-cigarettes in recent years.

Moreover, two months ago, San Francisco became the first major US city to ban the sale of e-cigarettes.

Between 2015 and 2018, half of the teenagers are in the survey said they were exposed to second-hand tobacco smoke.

Although this is a & # 39; significant downward trend & # 39; is from previous years, says Dr. Tan that passive smoking is much more harmful than e-cigarette emissions.

& # 39; This is very worrying, & # 39; said Dr. Tan. & # 39; Trends in the increase in second-hand spray cans are (also) important, but we must keep in mind that second-hand smoke is being reduced. & # 39;

The team recommends a number of proposals, including clean air laws, more education of second-hand spray cans with parents and interventions to reduce the vaping of young people.
