United States v. Oakland Cannabis Buyers' Cooperative

Background

A federal lawsuit challenged a nonprofit medical cannabis dispensary in Oakland and its director after California voters passed a law allowing seriously ill patients to use marijuana for medical purposes. The United States obtained a preliminary injunction halting the Cooperative’s distribution of marijuana under the federal Controlled Substances Act. The Cooperative violated that injunction, faced contempt proceedings, and the district court later modified the injunction to permit distributions in cases of claimed medical necessity.

Reasoning

The Court considered whether a medical-necessity defense can excuse manufacturing or distributing marijuana under the federal drug law. It explained that the law places marijuana in the strictest category (Schedule I) and contains only a narrow exception for government-approved research. Because Congress and the statute reflect a clear choice that marijuana has no accepted medical use for distribution, the Court held that judges may not read a medical-necessity exception into the statute. The Court reversed the Ninth Circuit’s ruling that had allowed such a defense and remanded the case.

Real world impact

The decision prevents dispensaries from using medical necessity to avoid federal enforcement, even where state law permits medical use. The ruling leaves open separate questions about whether individual patients or other narrow situations might be treated differently, and it does not resolve constitutional claims or all disputes between state and federal law.

Dissents or concurrances

Justice Stevens concurred in the judgment, agreeing distributors lack the defense but warning the Court not to announce broader statements about necessity beyond distributors; Justice Breyer did not participate.
