United States v. Hemani: Supreme Court Strikes Down Gun Ban for Marijuana Users Amid Civil Rights Enforcement Vacuum
On June 18, 2026, the Supreme Court ruled in United States v. Hemani that the federal ban on firearm possession by unlawful drug users is unconstitutional as applied to a regular marijuana user. The decision removes a tool used to address gun violence in Black and Brown communities, while the DOJ Civil Rights Division has abandoned pattern-or-practice police investigations, with no new probes opened since the Trump administration took office.
The Supreme Court's ruling in United States v. Hemani struck down a statute that prosecutors historically used to deter gun violence in marginalized neighborhoods, even as that same statute was applied unequally. As the Harvard Law Review Foreword (Vol. 136) observes, the Roberts Court often deploys constitutional doctrines that leave racial stratification intact—here, it limited a tool that, while flawed, served as a deterrent in communities where both drug enforcement and gun violence are concentrated. The decision comes at a time when the federal government is actively retreating from civil rights enforcement.
The DOJ Civil Rights Division, under the current administration, has dismissed Biden-era pattern-or-practice investigations into police departments in Louisville and Minneapolis. According to the ACLU, from 2021 to early 2025, the DOJ launched 12 such investigations; as of May 2025, the administration has opened zero new pattern-or-practice probes and has abandoned those that were underway (see ACLU press release, May 21, 2025; NYCLU press release, May 21, 2025; ACLU of Arizona press release, May 21, 2025). The ACLU of Kentucky specifies 11 investigations in some versions, but the majority of sources confirm 12. This abandonment of the strongest federal tool for reforming police departments—authorized by the Violent Crime Control Act of 1994, 42 USC 14141—leaves victims of police violence without a federal remedy.
The path forward requires Congress to restore staffing to the Civil Rights Division, compel the DOJ to resume pattern-or-practice investigations, and ensure that Section 2 of the Voting Rights Act is applied to address systemic inequities the Court's decision did not touch. Without these steps, communities of color lose both criminal justice tools and civil rights protections in one blow.
The humanitarian alternative
Congress should amend 18 U.S.C. § 922(g)(3) to clarify that any person who is a current, regular user of a controlled substance (including marijuana) is presumptively prohibited from possessing firearms, while creating a clear, time-limited pathway for individuals to demonstrate they are no longer a user—such as a 12-month abstinence period and a certified drug test. Separately, to address the tension with state-legal cannabis, Congress could reschedule marijuana under the Controlled Substances Act to Schedule III or lower, allowing states to regulate use while preserving the federal government’s ability to enforce firearm restrictions based on actual impairment risk, not just scheduling status. This approach would maintain public safety without undoing the narrow constitutional analysis, and it would give law enforcement a clear, enforceable standard.
Falsifiable predictions
What this entry claims will happen, and what data would prove it wrong. The Reckoner revisits these against current reality.
- Within 12 months, federal prosecutors will decline to bring charges under § 922(g)(3) in at least 60% of cases involving only marijuana use, citing the Hemani burden of proving addiction or dangerousness.
- At least one circuit court will extend Hemani to cover other controlled substances (e.g., cocaine or opioids) within 24 months, arguing the same as-applied logic.
