A new Centers for Disease Control and Prevention (CDC) study has shown that the figures for vaping by youth for 2017 to be almost the same as 2016 figures.
Data in the 2017 National Youth Tobacco Survey (NYTS), released by the CDC and the Food and Drug Administration’s (FDA) Center for Tobacco Products, indicates that 3.6 million middle and high school students used tobacco in the last 30 days. Of the 3.6 million, 2.1 million used e-cigarettes. The number of young people surveyed who smoked e-cigarettes in 2017 is very close to the 2016 total when e-cigarette use came in just under 2.2 million.
The study was based on a questionnaire filled out annually by roughly 20,000 students in grades 6 through 12, focusing on current users — defined as youth who said they had used a tobacco product in the previous 30 days.
