WASHINGTON DC – Millions of Americans who legally use marijuana may have gained significant Second Amendment protections Thursday after the U.S. Supreme Court unanimously ruled that the federal government cannot automatically prosecute a cannabis consumer simply for possessing a firearm.

In a 9-0 decision, the court sided with Texas resident Ali Hemani, a regular marijuana user charged under a federal law that bars firearm possession by unlawful users of controlled substances. The ruling could have major implications for Michigan’s more than $3 billion cannabis industry and the hundreds of thousands of consumers who legally purchase marijuana under state law.

The decision addresses one of the longest-running conflicts between state marijuana legalization and federal law. While Michigan and 23 other states allow adult-use cannabis sales, marijuana remains a Schedule I controlled substance under federal law. As a result, cannabis consumers have faced uncertainty about whether using marijuana could jeopardize their constitutional right to own firearms.

For years, federal law has prohibited firearm possession by anyone deemed an unlawful user of a controlled substance. Because marijuana remains illegal under federal law, that restriction has applied even to consumers who purchase cannabis legally under state programs.

The issue has been especially controversial among medical marijuana patients, military veterans, hunters, sport shooters, and concealed pistol license holders who legally consume cannabis under state law but risked running afoul of federal firearms regulations.

What The Supreme Court Decided

The case centered on Ali Hemani, a Texas man who admitted to regularly using marijuana while also possessing firearms.

Federal prosecutors charged Hemani under a section of the Gun Control Act that makes it illegal for unlawful drug users to possess guns.

However, the Supreme Court ruled that the government failed to demonstrate that prosecuting Hemani under the statute was consistent with the nation’s historical tradition of firearm regulation, the constitutional test established by the court’s landmark 2022 Bruen decision.

Writing for the court, Justice Neil Gorsuch concluded that while governments historically have restricted firearm possession by dangerous individuals, the federal government did not prove that Hemani’s circumstances justified such a prohibition.

The ruling does not eliminate the federal statute altogether. Instead, the court found that the law could not constitutionally be applied to Hemani under the facts of his case.

Legal experts expect the decision to trigger additional challenges to federal firearm restrictions involving marijuana consumers and potentially reshape how courts evaluate similar cases nationwide.

SUPREME COURT GUN RIGHTS RULING

  • Decision: 9-0

  • Plaintiff: Ali Hemani, Texas cannabis user

  • Issue: Federal ban on firearm possession by unlawful drug users

  • Court ruling: Government failed to justify applying the ban in this case

  • Michigan impact: Potentially affects hundreds of thousands of legal cannabis consumers

  • What’s next: Additional legal challenges and DEA rescheduling hearings beginning June 29

Why It Matters In Michigan

Michigan’s legal cannabis market generated more than $3 billion in sales in 2025, making it one of the largest marijuana markets in the United States.

The state also has a large population of hunters, recreational shooters, veterans, and firearm owners who have long questioned how federal gun restrictions apply to legal marijuana consumers.

The issue often arises when consumers attempt to purchase firearms from federally licensed dealers.

Federal Form 4473, which must be completed during firearm purchases, specifically asks whether the buyer is an unlawful user of marijuana or other controlled substances. The form warns that marijuana remains illegal under federal law regardless of whether it has been legalized or decriminalized under state law.

That contradiction has placed many cannabis consumers in a difficult position. A consumer may legally purchase marijuana from a state-licensed dispensary while simultaneously risking denial of a firearm purchase under federal regulations.

Thursday’s ruling does not completely eliminate those questions, but it significantly weakens the government’s ability to automatically treat all marijuana users as prohibited firearm possessors.

Impact Beyond Cannabis

The decision arrives at a pivotal moment for federal marijuana policy.

The Drug Enforcement Administration is preparing to hold hearings later this month on a proposal to move marijuana from Schedule I to Schedule III of the federal Controlled Substances Act.

If marijuana is ultimately rescheduled, pressure could increase on federal agencies and lawmakers to revisit additional restrictions that continue to treat cannabis consumers differently from users of other legal substances.

For Michigan’s cannabis industry, the ruling represents another sign that federal courts are increasingly scrutinizing long-standing federal marijuana policies that conflict with state legalization laws.

The Michigan Cannabis Regulatory Agency referred requests for comment to the Bureau of Alcohol, Tobacco, Firearms and Explosives. Additional reaction from state regulators, attorneys, and industry organizations will be included in follow-up coverage.

For now, cannabis consumers across Michigan have received what may become one of the most significant federal court victories since states first began legalizing marijuana.
