Tobacco use among high school students fell significantly last year, from 16.5% to 12.6%.

That’s according to a CDC and FDA study, which says that drop was driven largely by a 4% reduction in e-cigarette use, from 14% to 10%.

But in Arizona, state epidemiologists report only an insignificant downward blip in high-schoolers using electronic vaping products (a broader category that includes e-cigarettes and vapes). And those who do use them are doing so more often.

Nationally, e-cigarettes — mainly flavored varieties — have dominated tobacco use by middle school and high school students for the past decade.

Research shows half of kids who tried such products continued using them.

Nicotine use is unhealthy, addictive and can harm developing adolescent brains.
