The Food and Drug Administration Thursday authorized marketing of 20 nicotine pouches — the first time the products have been greenlit by the agency. Nicotine pouches are tobacco-free sachets filled with nicotine and flavorings that are held between the gums and lips similar to snus,

The FDA announced it has authorized the marketing of 20 Zyn nicotine pouch products, citing their greater health benefits vs. cigarettes and other tobacco products. It is the first time the agency has authorized the sale of nicotine pouches,

Zyn and the retailers who sell the product have run afoul of regulators in recent years. The FDA in April of last year warned 119 retailers to stop selling Zyn to underage people, and the company was ordered to pay $1.2 million last year for violating Washington, D.C.’s smokeless tobacco ban.
