Gun Rights Groups Back Cannabis Users in Supreme Court Case

A coalition of Second Amendment advocacy organizations filed an amicus brief with the U.S. Supreme Court on Thursday, urging justices to uphold a lower court decision that struck down the federal prohibition on gun ownership for cannabis users.

The Second Amendment Foundation (SAF) and California Rifle and Pistol Association are among the groups arguing that the longstanding federal ban violates constitutional protections. The brief supports a Fifth Circuit Court of Appeals ruling that found the restriction unconstitutional when applied to marijuana consumers in states where cannabis is legal.

The case centers on a decades-old federal statute that prohibits anyone who uses marijuana from purchasing or possessing firearms—even in states where cannabis is legal for medical or adult use. Gun purchasers must attest on ATF Form 4473 that they don't use cannabis, and lying on the form constitutes a felony.

The Constitutional Question

The gun rights coalition argues that the federal ban fails the Supreme Court's own test for firearms restrictions, established in the landmark 2022 New York State Rifle & Pistol Association v. Bruen decision. That ruling requires gun laws to align with the nation's "historical tradition" of firearm regulation.

"There's no historical precedent for disarming citizens based on their use of a substance that's legal in 38 states," the brief contends. The groups point out that the federal government can't demonstrate a consistent historical pattern of denying Second Amendment rights to people who consume intoxicating substances.

The case has created an unusual legal collision between two major policy debates: cannabis legalization and gun rights. As marijuana laws have liberalized across the country, the federal prohibition on gun ownership has increasingly come under scrutiny from both cannabis advocates and Second Amendment groups.

Industry Implications

The numbers underscore the scope of the conflict. Roughly 280 million Americans now live in states with some form of legal cannabis access—whether medical or recreational. Meanwhile, an estimated 40% of U.S. households own firearms. The overlap between these populations creates millions of potential cases where citizens face a choice between exercising two separate rights.

Cannabis industry operators have watched the case closely, recognizing that the gun ban affects not just consumers but also business owners and employees in the legal marijuana sector. Many state-licensed cannabis professionals have faced federal prosecution for possessing firearms while working in the industry.

The Justice Department has defended the ban, arguing that marijuana use poses safety risks that justify the restriction. Federal prosecutors have successfully brought charges against several cannabis users for illegal gun possession, even when both activities were legal under state law.

What's Next

The Supreme Court hasn't yet decided whether to hear the case on its merits. If the justices decline to take it up, the Fifth Circuit's ruling would stand—but only in that circuit's jurisdiction, covering Texas, Louisiana, and Mississippi. A Supreme Court decision would establish a nationwide precedent.

Legal observers note that the Court's conservative majority has shown increasing skepticism toward gun restrictions in recent years. The Bruen decision significantly raised the bar for justifying firearms regulations, requiring the government to prove historical analogues for modern gun laws.

The case could have far-reaching consequences beyond cannabis policy. A ruling in favor of gun rights could potentially affect other federal firearms restrictions, while upholding the ban might give the government more leeway to regulate gun ownership based on behavior or substance use.

The Court typically announces which cases it will hear several months in advance of oral arguments. A decision on whether to grant review in this case is expected within the next few months.
