On June 18, 2026, the Supreme Court affirmed a ruling for Ali Hemani, who had been prosecuted under the federal ban on firearm possession by an unlawful user of a controlled substance. Because marijuana remains federally controlled, the case reached conduct that may be legal under state cannabis law.
The Court concluded that applying 18 U.S.C. § 922(g)(3) to Hemani—based on his regular marijuana use and firearm possession in the home—was inconsistent with the Second Amendment. The government had not shown a historical analogue sufficient for that prosecution.
Why the Government’s Analogy Failed
The government pointed to historical laws involving habitual drunkards. The Court found that those laws targeted different people, for different reasons, and operated differently. The opinion emphasized that the prosecution did not depend on how much marijuana Hemani used, whether he was impaired while handling the gun, or whether he posed a danger.
What the Opinion Did Not Say
The decision does not create a right to carry or use a firearm while intoxicated. It does not invalidate laws targeting dangerous conduct, unlawful discharge, impaired handling, domestic violence, or other disqualifying circumstances. State firearm rules may raise different language and facts.
The opinion also does not change marijuana’s federal controlled-substance status. A state medical recommendation or adult-use purchase can still intersect with federal forms and statutes in ways that require current legal advice.
Facts Will Drive the Next Cases
Courts will now confront how Hemani applies to different patterns: infrequent use, simultaneous possession and cannabis, evidence of intoxication, other controlled substances, public carry, or a documented danger. A broad slogan—“marijuana users can own guns now”—skips the analysis that made Hemani prevail.
Practical Caution
Anyone facing a firearm purchase, federal background-check question, criminal case, protection order, or state licensing issue should consult a qualified attorney in the relevant jurisdiction. Do not answer a government form based on a social-media summary.
Hemani is a major Second Amendment decision because it rejects automatic lifetime-style disarmament on the theory the government presented. Its importance is not a reason to make it broader than the Court wrote it.
