A new study suggests health officials have less reason to worry about students using e-cigarettes: most teens are vaping "just flavoring," not nicotine.
This finding challenges many common assumptions and practices, and points to the need for vaporizer-specific research.
A team of researchers at the University of Michigan's Institute for Social Research examined the results of a nationwide survey of 15,000 students. More than 3,800 of the students said they'd used e-cigarettes.
Of those students, two-thirds vaped with a device using a flavored ingredient.
[It] seems inaccurate for the description of a device that the majority of youth do not use to vape nicotine.
The Food and Drug Administration recently began regulating the manufacture and sale of what it calls "Electronic Nicotine Delivery Systems," which include vaporizers, vape pens, hookah pens, electronic cigarettes. The study's authors say that term isn't accurate when describing vaporizers.
Vaping is becoming increasingly common among students. According to the FDA, over 3 million middle and high school students used e-cigarettes in 2015. That's up from an estimated 2.46 million in 2014.
