One in four teen e-cigarette users have tried ‘dripping’

Yale researchers found in a study that one in four high schoolers who use electronic cigarettes are inhaling vapors produced by dripping e-liquids directly onto heating coils, instead of inhaling from the e-cigarette mouthpiece, possibly increasing exposure to toxins and nicotine.

This form of e-cigarette use, known as “dripping,” is gaining in popularity among youth, who report it produces thicker clouds of vapor, a stronger hit in the back of the throat when inhaled, and a more pleasurable taste, according to the study, published online Feb. 6 in the journal Pediatrics.

Applying the liquid directly to the battery-powered coil heats it at a higher temperature than inhaling from a cartridge or tank, possibly increasing exposure to harmful chemicals like formaldehyde, acetaldehyde, and acrolein in the vapors, according to other existing research.

Research Suggests Some E-Cigarettes Can Produce Cancer-Causing Substances

A new study suggests a type of e-cigarette called a “tank system” can produce some carcinogens also found in regular cigarettes, and at similar levels.

While e-cigarettes do not burn tobacco to create new chemicals, including cancer-causing ones, some brands get so hot they can produce carcinogens,  The New York Times reports.

The study found tank systems produce formaldehyde, known to be a carcinogen. Formaldehyde is formed when liquid nicotine and other ingredients are subjected to high temperatures. The findings will appear later this month in Nicotine and Tobacco Research.
