“Juuling” is the latest craze among teens that’s raising health concerns. It’s named after a vaping device, the JUUL, which is intended to help adults kick cigarettes. The JUUL delivers nicotine and looks like a flash drive. It can actually be placed into the USB port of a computer to be charged, but “Juuling” has become a big thing among young people. Doctors are concerned that there is a misconception among teenagers using the device and other e-cigarettes, thinking they are safe.
