As our Tobacco + Nicotine team previously reported, FDA’s May 8, 2026 guidance (the 2026 Guidance or the Guidance) on enforcement priorities for certain unauthorized ENDS and nicotine pouch products created a path for products with pending premarket tobacco product applications (PMTAs) to remain on the market. That Guidance is now being challenged in federal court by advocacy organizations, threatening the viability of FDA’s enforcement discretion.

In October 2022, the U.S. Food and Drug Administration (FDA) announced that the Department of Justice (DOJ), on its behalf, filed complaints against six electronic nicotine delivery system (ENDS) companies in federal district courts, seeking permanent injunctions. These cases are important because they mark the first time the FDA has litigated against companies to enforce the Federal Food, Drug, and Cosmetic Act’s premarket review requirements for new tobacco products.
