E-cigarettes are battery-powered devices with a heating element that turn flavored liquid nicotine into a cloud of vapor users inhale - all developed by big US tobacco companies. This is different from the normal vaping method that slowly releases the liquid from a wick onto a hot atomizer, and is more risky. "When e-liquids are heated at high temperatures, like with dripping, they can produce high levels of carcinogenic compounds".
Yale researchers are out with a study that shows more teenagers are trying something new and possibly risky with electronic cigarettes. The study did not assess if the students added nicotine to the e-liquids used for dripping, or how frequently e-cigarettes were used for dripping, Science Daily reported.
"E-cigarette users use dripping to produce thicker clouds of vapor, a stronger throat hit, and make flavors taste better", researchers wrote.
Their findings, published in the journal Pediatrics, showed that 26.1 per cent had tried dripping. Vaping uses the reservoir and wick of the e-cigarette in a controlled way, but some will try to bypass the process and use a more manual form of vaping to increase the amount of vapor.
Electronic cigarettes are battery-operated devices that heat liquid and turn it into vapor - instead of smoke - which a person inhales.
Researchers have found though, that higher coil temperatures associated with dripping emit more harmful chemicals.
Story called e-cigarettes an adult product but said he would rather see a teenager use an e-cigarette than a traditional cigarette.
Housing White Paper quotes Pink Planning reports
The Tories' Housing White Paper released this week marks a shift away from the pretence that everyone can buy their own home. The Homes and Communities Agency will rebrand as Homes England, according to today's Government housing white paper.
In August, the Food and Drug Administration began regulating all tobacco products, including e-cigarettes, prohibiting sales to youths under the age of 18.
"Adolescents should not be using nicotine at all", Wilson said.
In an unrelated study previous year, Shihadeh and his colleagues approximated realistic dripping scenarios under laboratory conditions and then measured temperatures and emissions.
Krishnan-Sarin, however, said more research is needed on the long- and short-term effects of e-cigarettes.
And the liquid they're using could contain nicotine.
There's an alternative use of e-cigarettes trending among teenagers.
"This is one of the reasons why teens seem to like these devices", Krishnan-Sarin said.
