The device is branded JUUL, but the basis of the acronym (if it is one) is unknown. The Boston Globe called it "Juul" in a November story that called it "the most widespread phenomenon you've likely never heard of."
Though the device is small, its nicotine is much more concentrated than in typical vaping device, so "One puff is powerful," Carly Jensen of KOLN/KGIN-TV in Lincoln, Neb., reported this week. "Teachers are being warned to watch out for the dangers of the new device."
