In a landmark ruling that redefines the boundaries of federal regulatory power, the U.S. Supreme Court has ruled against the Food and Drug Administration (FDA) in a high-profile dispute over its authority to regulate tobacco products. The decision—stemming from FDA v. Alliance for Tobacco-Free Kids (No. 23-1187)—strikes at the heart of how agencies interpret their own power, effectively weakening the FDA’s ability to enact broad tobacco control measures without direct congressional approval.
The June 2025 decision is part of a broader rollback of the so-called Chevron deference, a legal doctrine that has for decades allowed federal agencies to interpret ambiguous laws. By reversing Chevron, the court has altered the regulatory landscape across a wide swath of issues, with tobacco regulation now squarely in the spotlight.
What the ruling says
The case focused on whether the FDA could treat certain nicotine delivery systems—like synthetic or flavored e-cigarettes—as “tobacco products” under the 2009 Family Smoking Prevention and Tobacco Control Act. The Court found that the FDA overstepped its bounds by applying its interpretation of “tobacco products” too broadly, asserting that only Congress has the authority to expand the definition.
Writing for the majority, the Court emphasized that administrative agencies must now receive clear authorization from Congress when interpreting statutory ambiguities. This limits the FDA’s flexibility in pursuing aggressive regulatory actions against emerging tobacco and nicotine products.
Background: Tobacco control and Chevron deference
The FDA has long relied on Chevron deference to regulate tobacco products, especially in gray areas where statutory language was unclear. Under Chevron, courts typically deferred to agency interpretations if the law was ambiguous and the interpretation was deemed reasonable.
This principle has been critical in the FDA’s expansion of its oversight to include e-cigarettes, synthetic nicotine, and flavored tobacco—products that did not exist when the 2009 tobacco law was written. However, critics argue the doctrine gave too much power to unelected officials.
The Court’s decision to overturn Chevron now shifts the burden back to Congress to spell out regulatory details in future laws.
Impact on FDA regulation and tobacco oversight
The ruling significantly constrains the FDA’s ability to:
- Impose marketing restrictions on flavored e-cigarettes
- Require premarket authorization for synthetic nicotine products
- Enforce bans or limits on tobacco advertising practices
- Expand its authority to regulate new nicotine technologies
This decision will likely stall or block several pending FDA enforcement actions. The agency must now return to Congress if it seeks new authority to regulate tobacco innovations that fall outside the 2009 law’s original scope.
Public health groups warn that the ruling could open the door to increased youth nicotine use, especially through unregulated vaping products. Industry advocates, meanwhile, hailed the decision as a victory against regulatory overreach.
What happens next?
Congress will now face increased pressure to update the Tobacco Control Act to reflect the evolving nicotine marketplace. Without explicit legislative action, the FDA’s hands are tied in areas like synthetic nicotine and emerging smokeless products.
This decision also sets a precedent for other federal agencies, requiring them to seek clearer statutory mandates before implementing major regulatory changes.
The ruling in FDA v. Alliance for Tobacco-Free Kids may become a turning point in the balance of power between the executive and legislative branches—and between regulators and the industries they oversee.
