(NBC News) – While vaping and e-cigarette use is an epidemic among teens, a survey shows adults in the United States are vaping less.
That’s according to the annual National Health Interview Survey.
Researchers from the University of Iowa examined the survey data for 2018, which involved roughly 153,000 people.
They found that e-cigarette use decreased from 2014 to 2017.
But it increased again in 2018, especially among those ages 18 to 24-years-old.
There was no increase among mid-age or older adults.
Other surveys show nearly 30-percent of high school students currently use e-cigarettes.
Even middle schoolers are vaping more each year.
Study authors say the trend is a public health concern.
