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

In a statement, the FDA said it has authorized the marketing and sale of Philip Morris International’s Zyn nicotine pouches. The pouches, which are placed between the lip and gum, are tobacco-free but contain nicotine. They come in different strengths and a variety of flavors such as citrus, coffee, peppermint and berry.

This marketing decision from the FDA covers 2 nicotine strengths, 3 mg and 6 mg, and 10 flavors of the small tobacco-free synthetic pouches.

The FDA authorized the marketing of 20 different Zyn nicotine pouch products -- the first brand to clear this regulatory hurdle in the increasingly popular class of single-use sachets of flavored nicotine designed to be placed between the lip and gums, which have been available for more than a decade.

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

The U.S. Food and Drug Administration authorized the marketing of 20 Zyn products on Thursday, marking the first such move by the regulator for the fast-growing nicotine pouches segment in the country.

The pouches are used by less than 2% of US teens, the FDA said in granting the application allowing them to continue to be sold.

The U.S. Food and Drug Administration on Thursday okayed the marketing of 20 Zyn nicotine pouch products after undertaking an extensive scientific review of them.

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 FDA has given marketing authorization to Zyn nicotine pouches. That doesn't necessarily mean they're safe to use, especially for young people, and experts say there's little evidence that they help adults quit smoking.
