Little pouches of nicotine sold by the brand ZYN were given the green light for marketing this week through the U.S. Food and Drug Administration’s premarket tobacco product application (PMTA) pathway.

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

Following an extensive scientific review, the U.S. Food and Drug Administration has authorized the marketing of 20 ZYN nicotine pouch products. Nicotine pouches—small synthetic fiber pouches containing nicotine—are designed to be placed between a person's gum and lip.
