Health problem facing decade, Juul e cigarettes and teens seem to be the new mantra of gen next. They appear with a sleek device resembling a flash drive that can fit in their palms. But instead of flash drive it stores nicotine.

They inhale the device just like a cigarette, then they blow into their backpacks or on their sweaters when the teacher is not paying any attention to them said Elijah Luna, 16, a sophomore at Vista del Lago High School in Folsom, Calif., about 30 miles east of Sacramento.

The vapor cloud dissipates quickly so no one actually notice it. The device is a Juul, a popular electronic cigarette, that’s a furor among teens, especially in well to do homes. Milagros Vascones-Gatski, a substance abuse counselor at Yorktown High School in Arlington, Va said that it will be a long lasting problem. In almost 17 years of working she has not witnessed such an upsurge of tobacco product. She added that three or four students are held smoking e cigs on campus each week and are debarred.

Vascones-Gatski, along with other perturbed and health care authority contemplates juuling beyond just a youthful rebellion. As it is high in nicotine they are concerned that the device is very compelling for its endangered population. To fight the escalation of the devices some schools have debarred flash drives as well to evade any confusion between the items.
