Teen vaping in the U.S. has dropped to its lowest level in a decade. That's according to new survey data reported Thursday. U.S. health officials say the drop in the number of teens using e-cigarettes has pushed the underage vaping rate to below 6%. They attributed the decline to fewer high school students using Elf Bar and other vapes that come in fruit and candy flavors. The drop in vaping didn’t coincide with a rise in use of other products, such as nicotine pouches. Sales of small, flavored pouches like Zyn have surged among adults. But the survey shows their use remains rare among teens.
