 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 would create a registry of vape products approved by the FDA. The state would find stores that sell products not included on the registry list. The bill now goes to the full senate. It is unclear when or if it will be taken up in this session.
