Best way to help teens addicted to vaping? No one knows

WASHINGTON — The nation’s top health authorities agree: Teen vaping is an epidemic that now affects some 3.6 million underage users of Juul and other e-cigarettes. But no one seems to know the best way to help teenagers who may be addicted to nicotine.

E-cigarettes are now the top high-risk substance used by teenagers, according to the latest U.S. figures, which show that Juul and similar products have quickly outpaced cigarettes, alcohol, marijuana and other substances that have been tracked over more than four decades.

The handheld devices heat a liquid solution that usually contains nicotine into an inhalable vapor.
