From Science Daily: US teens are more likely to vape for the flavorings found in e-cigarettes rather than nicotine, suggests research published online in the journal Tobacco Control.
The findings call into question the designation of e-cigarettes as Electronic Nicotine Delivery Systems (ENDS) and suggest that the recent spike in the popularity of e-cigarettes among this age group doesn't signal a 'nicotine epidemic' as feared, conclude the researchers.
It is widely assumed that teen vapers are vaping nicotine, so in a bid to find out exactly what substances they are vaping, the researchers quizzed almost 15,000 students about their vaping experiences as part the 2015 Monitoring the Future Survey -- an annual, nationally representative study of 8th, 10th, and 12th grade students.
Some 3837 of the students had vaped at some point, and of those who had vaped within the past month, 1701 had done so at least once; 1085 had done so up to five times; and 616 had done so more than half a dozen times.
Among those who had ever vaped "just flavoring" was by far the most commonly vaped substance at last use for around two thirds of students across all three grades.
This answer was more common than all the others combined.
