After reviewing the scientific evidence, the agency has decided 20 ZYN nicotine pouch products can legally be sold in the US.

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.

The FDA authorized the marketing of 20 Zyn products on Thursday, marking the first allowance for the fast-growing nicotine pouches.
