 A UNC professor has likened the effort to curb youth vaping as a game of whack-a-mole. You try to understand what's in a product, what's going in the bodies of these young people, and it's just really hard to understand, and another one pops up. It's unmanageable. A committee in the state senate last week signed off on a bill that could create a registry of vape products approved by the FDA. The state of North Carolina would fine stores that sell products not included on the registry list.
