The Dormant Commerce Clause and the Future of Cannabis Markets

On August 12, 2025, the Second Circuit handed down its ruling in Variscite NY Four Inc. v. New York Cannabis Control Board, striking down New York's licensing preferences that favored in-state residents. The decision has significant implications for every state cannabis market in the country - and opens the door to a new era of interstate commerce challenges.

The Dormant Commerce Clause

The Dormant Commerce Clause is a constitutional doctrine derived from the Commerce Clause of Article I, Section 8. While the Commerce Clause explicitly grants Congress the power to regulate interstate commerce, the "dormant" aspect implies a negative restriction on states: they may not pass laws that unduly burden or discriminate against interstate commerce, even when Congress has not acted.

In the cannabis context, this is explosive. Nearly every state with a legal cannabis program has some form of residency requirement or in-state preference baked into its licensing framework. The Second Circuit's ruling calls the legality of those provisions into serious question.

The Variscite Decision and Its Reach

The court found that New York's licensing structure, which gave preference to applicants with ties to the state, violated the Dormant Commerce Clause by discriminating against out-of-state operators. This follows on the heels of Northeast Patients Group v. Maine and Toigo v. Missouri, both of which raised similar issues.

Cannabis attorney Andrew Deweese has noted that the standing problems that historically shielded these state programs from challenge are eroding. As more operators gain standing through denied applications or competitive harm, the floodgates for DCC challenges are opening.

Oregon's Total THC Rule - Low-Hanging Fruit

Oregon's total THC measurement rule for hemp products is another area ripe for a Dormant Commerce Clause challenge. By imposing stricter testing standards than the federal framework requires, Oregon arguably creates an impermissible barrier to interstate commerce in legal hemp products. This kind of regulatory overreach is precisely the sort of state action the DCC was designed to prevent.

The Federal Hemp Debate

The broader federal hemp debate intersects with these DCC concerns. As states impose varying and sometimes contradictory regulations on hemp-derived products, the resulting patchwork creates the exact kind of interstate commerce barrier that the Dormant Commerce Clause prohibits. Whether Congress steps in to create uniform standards - or whether the courts force the issue - remains to be seen.

What is clear is that the era of purely state-by-state cannabis regulation is coming under increasing legal pressure. Operators, investors, and regulators should be paying close attention to how these cases develop.
