WASHINGTON (AP) – U.S. health officials will begin cracking down on most flavored e-cigarettes that are popular with underage teenagers. But the plan from the Trump administration includes major exceptions that benefit companies that make and sell e-cigarettes and adults who use the nicotine-delivery devices. The Food and Drug Administration said Thursday the policy won’t affect menthol or tobacco flavors. The policy also won’t affect large, tank-based vaping products sold in vape shops that cater to adults. Those changes are a major step back from President Donald Trump’s original plan announced in September, which would have banned nearly all flavors in all vaping products.
