Gonzales v. Raich

Background: Prop 215 and two California patients

In 1996, California voters passed Proposition 215, the Compassionate Use Act, making California the first state to legalize medical cannabis under state law ^[1]. The federal Controlled Substances Act (CSA), passed in 1970, still classified cannabis as Schedule I — no accepted medical use, high abuse potential ^[2].

Angel Raich and Diane Monson were two California residents using cannabis on their physicians' recommendations. Raich, of Oakland, had an inoperable brain tumor and a list of other serious conditions; her doctor stated that cannabis kept her alive ^[3]. Monson, of Oroville, used cannabis for chronic back pain and cultivated six plants at home. On August 15, 2002, federal DEA agents and county sheriffs raided Monson's home. The local officers concluded she was in compliance with state law; the DEA seized and destroyed her plants anyway ^[3].

Raich and Monson sued to block federal enforcement against them, arguing the CSA exceeded Congress's Commerce Clause power as applied to purely intrastate, noncommercial, medically necessary cannabis.

Path to the Supreme Court

The case was originally filed as Raich v. Ashcroft in the Northern District of California, which denied a preliminary injunction. On appeal, the Ninth Circuit reversed in December 2003, holding that the plaintiffs had shown a strong likelihood of success — their conduct was a 'separate and distinct class of activities' from the interstate drug market Congress meant to regulate ^[4].

The Ninth Circuit relied heavily on two recent Rehnquist Court federalism decisions, United States v. Lopez (1995) and United States v. Morrison (2000), which had struck down federal statutes for exceeding Commerce Clause authority ^[5]. Advocates believed those cases signaled a real limit on federal power over local, noneconomic conduct.

The United States petitioned for certiorari. By the time the Supreme Court heard argument on November 29, 2004, John Ashcroft had been succeeded as Attorney General by Alberto Gonzales, and the case was renamed Gonzales v. Raich ^[3].

The decision: Wickard's long shadow

On June 6, 2005, the Court ruled 6–3 for the government ^[3]. Justice Stevens's majority opinion — joined by Kennedy, Souter, Ginsburg, and Breyer, with Scalia concurring separately — leaned on Wickard v. Filburn (1942), the New Deal case that upheld federal wheat quotas against a farmer growing wheat for his own consumption ^[3][6].

The reasoning: even purely local, noncommercial cultivation, taken in the aggregate, could substantially affect the interstate market Congress was trying to regulate. Homegrown medical cannabis could leak into the illicit market, or displace demand for illicit cannabis, either way affecting interstate commerce. Under the CSA's comprehensive scheme, Congress could rationally conclude that carve-outs would undermine the whole regime ^[3].

Justice Scalia concurred separately, grounding his vote in the Necessary and Proper Clause rather than a pure Commerce Clause theory ^[3].

Justice O'Connor dissented, joined by Chief Justice Rehnquist and Justice Thomas, warning that the majority had gutted Lopez and Morrison and given Congress essentially unlimited reach into local conduct ^[3]. Justice Thomas wrote a separate, sharper dissent: 'If Congress can regulate this under the Commerce Clause, then it can regulate virtually anything — and the Federal Government is no longer one of limited and enumerated powers' ^[3].

Aftermath for the plaintiffs

The case went back down on remand. Raich pursued a separate theory — that the Fifth Amendment's substantive due process and the common-law defense of medical necessity should shield her. In March 2007, the Ninth Circuit rejected those arguments in Raich v. Gonzales ^[7]. Raich continued using cannabis publicly and was never federally prosecuted; Monson likewise avoided prosecution. Neither woman was ever criminally charged after the litigation.

Legacy and what Raich did — and didn't — do

A few things Raich actually established:

• The CSA's Schedule I classification of cannabis applies inside states that have legalized it. State medical or adult-use laws don't preempt federal law ^[3].
• Federal agents retain authority to raid, seize, and prosecute even fully state-compliant patients and providers.
• Commerce Clause challenges to federal drug prohibition are effectively dead at the Supreme Court.

A few things Raich did not do, contrary to common misreadings:

• It did not strike down Prop 215 or any state medical marijuana law. Those remain in force as state law.
• It did not require states to help enforce federal cannabis law. Under the anti-commandeering doctrine (Printz v. United States, 1997), states can decline to enforce federal drug law, which is exactly what every legalization state now does ^[8].
• It did not settle the medical necessity defense — that was resolved separately, and unfavorably for patients, in United States v. Oakland Cannabis Buyers' Cooperative (2001) ^[9].

The practical compromise the country has lived under since Raich — legal weed under state law, illegal weed under federal law, tolerated by prosecutorial discretion (the 2013 Cole Memo, the annual Rohrabacher–Farr appropriations rider protecting state medical programs) — exists because Raich foreclosed the constitutional path and left only the political one ^[10].

Common myths about Raich

Myth: 'Raich made medical marijuana illegal.' Disputed It didn't. It confirmed that federal law still applies; state medical programs continued and expanded.

Myth: 'Justice Thomas voted against medical marijuana patients.' Disputed Thomas dissented for Raich and Monson, on federalism grounds. He wrote one of the strongest defenses of the plaintiffs' position.

Myth: 'Raich means the DEA can arrest any state-legal dispensary any time.' Legally, yes — the authority exists. In practice, since the 2014 appropriations rider, DOJ has been prohibited from spending funds to prosecute state-compliant medical operators, a limit the Ninth Circuit enforced in United States v. McIntosh (2016) ^[10]. That's a spending restriction, not a constitutional shield, and Congress renews it annually.
