Supreme Court Narrows Gun Ban for Marijuana Users in Hemani Ruling

The Supreme Court’s unanimous ruling in United States v. Hemani (24-1234) on June 18, 2026, is a narrow constitutional carve-out that leaves the federal statute intact but hollows out its practical reach. By a 9-0 vote, the Court held that the federal ban on firearm possession by 'unlawful drug users' cannot automatically strip Second Amendment rights from a Texas man who uses marijuana a few times a week—without evidence of addiction or dangerousness. This decision does not overturn 18 U.S.C. § 922(g)(3), but it effectively ends routine enforcement against millions of occasional cannabis consumers in states where marijuana is legal under local law.

The practical consequence is a two-tiered system: federal prosecutors can still charge individuals with addiction histories or evidence of impairment, but enforcement against casual users is now off-limits. This creates a vacuum in states with weak background-check laws and high gun-violence rates—disproportionately impacting Black and Brown communities, where federal firearm prosecutions under § 922(g)(3) have historically been a tool to disrupt gun trafficking. Without a clear standard for 'addiction' or 'dangerousness,' the ruling invites inconsistent application across circuits, potentially worsening enforcement disparities.

The proper fix is congressional action to update 18 U.S.C. § 922(g)(3) with evidence-based criteria or to deschedule marijuana federally, eliminating the conflict between state marijuana laws and federal prohibition. Until then, the ruling leaves public safety agencies with fewer tools and risks unequal enforcement across jurisdictions.
