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

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.

These items have become popular in c-stores as traditional tobacco sales plunge, and their approval sets the stage for continued growth.
