The increase in vaping by 10th and 12th graders was the largest
year-over-year jump for any substance ever measured by the survey,
which started 44 years ago.
The annual survey, which also measures use of other substances
including marijuana, alcohol and opioids, questioned more than
44,000 students from 8th, 10th and 12th grades in U.S. public and
private schools.
The percentage of high school students who used nicotine-based
vaping devices, known as e-cigarettes, has risen by a third over the
past year, the survey showed.
E-cigarettes have been a divisive topic in the public health
community. Some focus on the potential benefit of shifting lifelong
smokers to less harmful nicotine products, while others fear it will
create a new generation addicted to nicotine.
Last month, the U.S. Food and Drug Administration, facing mounting
pressure to act on the rising popularity of vaping devices,
announced sweeping new restrictions on flavored tobacco products,
including e-cigarettes.

The one-year rise in vaping were mirrored by changes in the
perception of availability of e-cigarretes, the institute said in
its report, with more 8th and 10th graders reporting that vaping
devices and e-liquids containing nicotine were easier to obtain in
2018 than in 2017.
E-cigarette makers, including San Francisco-based Juul Labs Inc,
have also faced scrutiny from the FDA amid the increase in teenage
use of the devices, which look like a USB flash drive and vaporize a
flavored liquid containing nicotine.
Juul said in November it would pull popular flavors such as mango,
cucumber and fruit from many retail store shelves to reduce teenage
use of its products.
