The U.S. Food and Drug Administration (FDA) has granted marketing authorization to 20 of Philip Morris International’s (PMI) ZYN brand nicotine pouch products, a landmark decision that solidifies the brand’s position as the leader in the rapidly growing smokeless nicotine market. The authorization, which covers various flavors including Wintergreen and the unflavored “Chill” in both 3 mg and 6 mg strengths, was met with a surge in PMI’s stock price as investors reacted to the regulatory green light.
