ZYN pouches contain no tobacco, only nicotine, offering a potentially less harmful option for tobacco users, with lower levels of cancer-causing constituents than traditional tobacco products.

Federal health officials are backing the health benefits of nicotine pouches, ruling that Philip Morris International’s Zyn can help adult smokers cut back or quit cigarettes.

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.
