Study: 1 in 4 Teen E-Cigarette Smokers Use Dangerous “Dripping” Technique

By Alan Lyndon

e-cigaretteOne in four high school teens who use electronic cigarettes have tried “dripping” e-liquids directly into the heating coils of the device to produce more intense sensations, according to a new study from Yale University.

Researchers surveyed 7,045 Connecticut high school students and found that more than 26 percent of e-cigarette users were dripping to produce effects including thicker clouds of vapor, better flavor and a stronger throat hit.

While it is still too early to show the negative effects of e-cigarettes and dripping, in particular, the study authors say that applying liquid nicotine directly onto the devices’ atomizers can expose users to higher temperatures and toxic chemicals like formaldehyde, acetaldehyde and acetone.

“Everybody assumes vaping is a safer way (than cigarettes) of administering nicotine, but we know so little about the risks of vaping,” said Suchitra Krishnan-Sarin, professor of psychiatry at Yale and first author of the study.

According to the Centers for Disease Control and Prevention (CDC),  electronic vapor products, including e-cigarettes, are now the most commonly used tobacco products among U.S. high school students, surpassing conventional cigarettes in 2014.

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. White, male teens were most likely to use e-cigs for dripping, according to the study published online in the February 6 edition of the journal Pediatrics.

“Dripping is a more labor-intensive method of vaping in which the user manually applies a few drops of liquid directly to the exposed heating coil of the e-cig every so many puffs,” Alan Shihadeh, professor of mechanical engineering and director of the Aerosol Research Laboratory at the American University of Beirut, told CNN.com.

Shihadeh said that in addition to the other enhanced sensations derived from the procedure, some people prefer dripping because “it allows them to conveniently change from one liquid flavor to another without wasting liquid.”


  1. Use CBD and never use nicotine and you are correct, no addiction. Just be totally, totally sure that your CBD is pharmaceutical grade and unadulterated–and much of it is adulterated read:


    “Dripping” with nicotine simply makes the body addicted to higher nicotine “rewards,” resulting in the desire for more potent inhalations. Nicotine is an addictive substance and many, once started are hooked.

    CBD is another story and an interesting one. The body’s cabbanoid system is fascinating.

  2. Please educate yourselves about the real data. Dripping is just another form of vaping. It uses the same process that regular vaping does, and existed before vaping.

    Vaping had still to be shown to have detrimental effects to the human body. Ther fact that nicotine is an optional additive doesn’t seem to affect you at all. I vape 0mg nicotine and about 1 mg CBD per ml. It has made a vast difference in my quality of life. My brain isn’t the huge battlefield it was.
