FDA authorizes Zyn nicotine pouches, citing public health benefits for adult smokers, despite concerns over flavored products' appeal to teens.

The Food and Drug Administration OK'd 10 Zyn flavors, including coffee, mint and menthol. It's the first time regulators have authorized sales of nicotine pouches, which are the fastest-growing segment of the U.S. tobacco market.

Zyn products will be allowed to stay on the market after federal health officials said Thursday that the popular nicotine pouches can help adult smokers cut back or switch completely.
