2023 Lawsuit Challenging Federal Cannabis Prohibition is the Most Consequential Federal-Court Test of State Legalization in Years.

What is the lawsuit?

In October 2023 a group of four cannabis businesses (Canna Provisions, delivery operator Gyasi Sellers, grower Wiseacre Farm, and multi-state operator Verano Holdings) filed a bold constitutional challenge to the federal ban on marijuana. Represented by attorney David Boies, the plaintiffs asked a federal court to declare that applying the Controlled Substances Act (CSA) to state-legal cannabis activity exceeds Congress’s constitutional powers, effectively asking the courts to carve out state-legal cannabis from the federal prohibition.

Timeline & procedural posture

The suit was filed in U.S. District Court for the District of Massachusetts in October 2023. Plaintiffs argued that Gonzales v. Raich (2005) – the Supreme Court decision that gave the federal government authority to regulate locally cultivated marijuana under the Commerce Clause is outdated. The district court heard motions and oral argument through spring 2024. In July 2024, U.S. District Judge Mark G. Mastroianni dismissed the complaint, saying the court was bound by existing Supreme Court precedent and that only the Supreme Court could overturn Raich. The plaintiffs appealed. (reuters.com) The appeal moved to the First Circuit, which reviewed the case and in an opinion issued in 2025 affirmed the district court, concluding that Congress’s authority under the Commerce Clause still encompasses the CSA’s control over marijuana even when the activity is intrastate. After the First Circuit ruling, the plaintiffs filed a petition for the U.S. Supreme Court to hear the case (a cert petition was filed in late October 2025). As of early December 2025, the matter is pending before the high court’s cert-consideration calendar; the justices are set to determine whether to take the case. (Justia)

Who are the plaintiffs?

The plaintiffs represent a mix of small and large operators: Canna Provisions is a Massachusetts retailer; Gyasi Sellers is a delivery-business owner; Wiseacre Farm is a cultivator; and Verano is a publicly traded multi-state operator. The plaintiffs retained David Boies and other counsel who argue the legal landscape has shifted dramatically since Raich, citing state legalization and changing federal enforcement policies. The U.S. Department of Justice defended the CSA and relied on Raich and related precedent. (reuters.com)

What’s at stake for the cannabis industry

If the Supreme Court agrees to hear the case and ultimately rules for the plaintiffs in a way that limits the CSA’s reach over state-legal, intrastate cannabis commerce, the effects would be seismic:

  • Banking and finance: Federal prohibition is the main reason many banks avoid or restrict cannabis clients. A ruling narrowing federal reach could open mainstream banking, credit, SBA loans and investment to state-legal businesses. (reuters.com)
  • Taxes and IP: Businesses now face tax disadvantages (e.g., Section 280E) and difficulty enforcing trademarks because federal law treats marijuana as illegal. A change in federal authority could allow tax parity and stronger IP protections. (reuters.com)
  • Interstate commerce and regulation: Depending on how the Court frames its ruling, Congress might retain some regulatory authority over interstate marijuana commerce, or the decision could force Congress to create a new federal regulatory framework — or leave states to police commerce among themselves. The precise contours would matter greatly for licensing, product standards, and supply chains. (Justia)
  • Criminal enforcement and public policy: A legal limit on federal enforcement against state-legal actors would reduce federal criminal exposure for many businesses and consumers, but federal law would still govern trafficking across state lines unless Congress acted otherwise.

What to watch next

The immediate next step is whether the Supreme Court grants review. If it does, a decision could come a year after briefing and oral argument — and could either confirm the status quo (leaving reform to Congress) or prompt a constitutional narrowing of federal authority that forces Congress to decide whether and how to regulate cannabis at the national level. If the Court declines review, the First Circuit ruling stands and change will remain legislative or administrative. (Supreme Court)

Bottom line

The suit is the most consequential federal-court test of state legalization in years. Even though early rulings bounced the plaintiffs back, the case has already pushed long-running policy questions into the open — and the industry is watching the cert docket closely.
