No longer the hot new thing? Teen vaping falls, study says

A government survey released Thursday suggests the number of high school and middle school students using electronic cigarettes fell to 2.2 million last year, from 3 million the year before.

Health officials have worried about the booming popularity of vaping products among kids and the potential impact on adult smoking rates in the future.

Studies suggest many kids who vape use the products less often than kids who smoke cigarettes — a sign that vaping seems to be more social and experimental, some experts said.

[...] health officials have warned nicotine in e-cigarettes is harmful to developing brains.

Based on the survey responses, the CDC estimates that the number of middle and high school students using tobacco products fell to 3.9 million last year, from 4.7 million the year before.
