The students wait eagerly for their teachers to turn their backs.

That’s their cue to reach quietly for a small, sleek device they can easily conceal in their palms. It resembles a flash drive, but instead of computer files, this device stores nicotine.

They take a hit, sucking on the device as they would a cigarette. Then, “they blow into their backpacks … or into their sweater when the teacher isn’t looking,” said Elijah Luna, 16, a sophomore at Vista del Lago High School in Folsom, Calif., about 30 miles east of Sacramento.

The vapor cloud is so small and dissipates so quickly that teachers are usually none the wiser, said Luna, who added he’s never tried it himself.

The device is a Juul, a popular electronic cigarette that’s a sensation among teens, especially in wealthier neighborhoods — and a nightmare for school administrators and public health advocates.
