ZYN pouches contain no tobacco, only nicotine, offering a potentially less harmful option for tobacco users, with lower levels of cancer-causing constituents than traditional tobacco products.

The FDA said "an extensive scientific review" found the products were found to pose lower risks of cancer and other serious health conditions compared to cigarettes and smokeless tobacco products.

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.

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