Federal health officials on Thursday backed the public health benefits of nicotine pouches, authorizing Philip Morris International’s Zyn to help adult smokers cut back or quit cigarettes.

The Food and Drug Administration (FDA) announced on Thursday that it authorized the marketing of Zyn nicotine pouches but will be "closely monitoring youth use." Newsweek reached out to Zyn for comment.

The U.S. Food and Drug Administration formally authorized Zyn nicotine pouches for sale after conducting an "extensive scientific review" about their safety.
