E-cigarettes are often touted as safer alternatives to cigarettes but they've also been tied to a spike in poisonings.

Vaping is becoming more popular especially to teenagers, even with all the studies claiming the harmful effects it gives to the body.

"Kids are actually using these electronic products for other behaviors, not just for vaping e-liquids from cartridges or tanks".

We had anecdotal evidence that youth were choosing to directly drip liquid onto exposed heater coils, instead of the normal use of an e-cigarettes where an automatic wick feeds the liquid into the electrical heater.

People who drip say it tastes better and produces a thicker cloud of vapor, but it also increases the amount of nicotine and unsafe chemicals like formaldehyde. What's worse is that a lot of teenagers have already tried "dripping".

One in four teens who use e-cigarettes say they've dripped, letting the nicotine-based liquid drop onto the e-cigarette's heating coils and then inhaling the vapors. But still, this practice is a cause for concern, many experts agree.

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

While not all e-cigarette products contain nicotine, increased nicotine levels can lead to stronger throat hits, too.

White students overall and boys were more likely than others to have tried dripping, the researchers said.

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

The authors called for additional research into the dangers of dripping and more education for youths.

The U.S. Food and Drug Administration has announced its intention to regulate e-cigarettes as tobacco products, but hasn't yet rolled out its new rules.
