SCOTUS Gun Watch 4/27/2026
The Supreme Court agreed to hear Harrison v. United States, a case challenging federal law that strips Second Amendment rights from medical marijuana users. The justices will decide whether 18 U.S.C. § 922(g)(3) violates the Constitution when applied to state-legal cannabis patients. Michael Harrison, a Colorado veteran with PTSD, was convicted of unlawful firearm possession after federal agents discovered his medical marijuana card during a routine background check audit. Harrison legally owned firearms for fifteen years before obtaining his medical cannabis license in 2023. The case marks the Court's first major gun rights decision since New York State Rifle & Pistol Association v. Bruen established the historical tradition test. Lower courts split on whether marijuana prohibition meets this standard.
Background and Context
Federal law prohibits anyone who is an "unlawful user of or addicted to any controlled substance" from possessing firearms. The ATF interprets this to include all marijuana users, regardless of state legalization. Thirty-eight states now allow medical marijuana, and twenty-one permit recreational use. An estimated 128,000 Americans hold both concealed carry permits and medical marijuana cards. The Tenth Circuit upheld Harrison's conviction, citing the government's interest in public safety. But the Fifth Circuit ruled differently in Texas v. Rodriguez, creating the circuit split that prompted Supreme Court review. Harrison's attorneys argue that historical evidence shows the Founders never intended substance use alone to disqualify citizens from gun ownership. The government maintains that intoxicating substances and firearms create inherent dangers.
What This Means for Gun Owners
A ruling for Harrison could restore gun rights to millions of Americans who use marijuana legally under state law. Currently, these individuals face a choice between medicine and constitutional rights. Form 4473 asks buyers whether they use marijuana, making legal gun purchases impossible for medical patients. Harrison's victory would likely invalidate this question and related ATF guidance. The decision could also affect other controlled substances prescribed by doctors. Veterans groups filed amicus briefs supporting Harrison, noting that many combat veterans rely on medical marijuana for PTSD treatment. The ruling may arrive before the 2026 midterm elections, potentially affecting races in states with large populations of medical marijuana patients. Gun stores report losing customers who refuse to lie on federal forms but need cannabis for medical conditions.
Industry Impact
Firearms manufacturers and retailers watch this case closely. A pro-Harrison ruling could expand their customer base significantly. Gun sales in Colorado dropped twelve percent after the state clarified that medical marijuana patients cannot purchase firearms. Industry analysts estimate that nationwide sales could increase by eight to fifteen percent if the prohibition falls. Background check systems would require updates to remove marijuana-related disqualifications. The case also affects firearms training companies and shooting ranges, many of which currently exclude known marijuana users. Cannabis industry lawyers expect increased business as gun owners seek medical marijuana cards they previously avoided. Some manufacturers already plan marketing campaigns targeting medical marijuana patients, pending a favorable Supreme Court decision.
What to Watch Next
Oral arguments are scheduled for October 2026, with a decision expected by June 2027. Gun rights groups plan coordinated amicus briefs emphasizing the historical tradition test from Bruen. The Biden administration will defend the current law, likely arguing that public safety justifies the prohibition. State attorneys general from marijuana-legal states may file briefs supporting Harrison. Lower courts nationwide have stayed similar cases pending this decision. Congress could also act before the Court rules. Representative Thomas Massie introduced legislation removing marijuana users from prohibited persons lists. The bill has bipartisan support in both chambers. Veterans organizations plan lobbying efforts regardless of the Court's timeline.
DownRange Bottom Line: This case could restore gun rights to millions of Americans caught between contradictory state and federal laws. The historical tradition test from Bruen gives Harrison a strong chance of victory.
