In March, Congress amended the Federal Food, Drug, and Cosmetic Act to give the Federal Drug Administration authority to regulate synthetic nicotine in the same way it regulates other tobacco products. Regulators hope to close the loophole that allowed companies to continue selling flavored e-cigarettes, which many say enticed teens and young adults, even after the FDA cracked down on flavored e-cigarettes back in 2020. Congress’s move to clamp down on flavored nicotine products is part of regulators and policymakers' larger push to deter rising nicotine use among teenagers.
