New Teen E-Cigarette Trend 'Dripping' Raises Health Concerns

New Teen E-Cigarette Trend 'Dripping' Raises Health Concerns

There's a rising trend among e-cigarette users, and a survey finds that teens make up the largest group who practice "dripping".

An increasing number of high school students, who use e-cigarettes, are also "dripping", Yale University researchers reported in a new study.

It has grown in popularity because it produces a stronger hit, a thicker cloud of vapor, and increased taste.

"This study is the first systematic evaluation of the use of dripping among teens", said Suchitra Krishnan-Sarin, a professor in the department of psychiatry at the Yale University School of Medicine and the lead author of the study.

The culprit, according to the CDC, is the liquid nicotine in the e-cigarettes. "It changes the brain chemistry, and adolescents are uniquely susceptible to the addictive properties of nicotine". Krishnan-Sarin said a variety of vapor patterns can be produced with thicker clouds, such as "tornadoes and rings".

The study, conducted in CT, found that among 1,874 students, 1,080 had tried vaping.

Liverpool: Klopp takes the blame for Wolves loss
Klopp added: "For each single performance maybe there is an explanation, but I'm not sure that we should look for it". Shane Long's victor against Liverpool in the EFL Cup on Wednesday was only his third goal this season.

Story called e-cigarettes an adult product but said he would rather see a teenager use an e-cigarette than a traditional cigarette.

Better flavor was the reason cited by almost two out of five students who dripped, and simple curiosity attracted 22 percent.

Krishnan-Sarin said in general people who use e-cigarettes tend to puff on them throughout the day, and that researchers don't know the short- and long-term consequences of exposing lungs to the vapors.

Here is a recent unrelated study on dripping published past year. They observed that volatile aldehyde emissions (like formaldehyde) were higher with direct dripping than with conventional e-cigarette or combustible cigarette use. "They like that they can do these novel things with them", she told CBS News.

"This points out why we need FDA providing oversight over these products and how they're being used in the real world", Billings said.

Funding for it was provided by the National Institutes of Health and the U.S. Food and Drug Administration Center for Tobacco Products. Pediatrics. Feb. 6, 2016,
