In a unanimous decision released Thursday, the U.S. Supreme Court sided with a Texas man and narrowed a key federal law that had barred firearm possession by unlawful users of controlled substances, including marijuana. The ruling in United States v. Hemani limits criminal enforcement of 18 U.S.C. § 922(g)(3) in cases involving regular marijuana use without additional evidence of impairment or danger.
Justice Neil Gorsuch wrote the opinion. The Court affirmed lower court decisions that dismissed charges against Ali Danial Hemani. In 2022, FBI agents searched his Texas home and recovered a Glock pistol along with marijuana. Hemani told agents he used marijuana about every other day. Federal prosecutors later charged him under the statute, which makes it a felony for any “unlawful user of or addicted to any controlled substance” to possess a gun.

The Supreme Court held that applying the law to Hemani violated the Second Amendment. Using the history-and-tradition framework from the 2022 Bruen decision, the justices found the modern categorical ban does not align closely enough with historical regulations. Laws targeting “habitual drunkards” historically required proof of severe, ongoing incapacity and often involved judicial process before disarming someone. The federal statute, by contrast, automatically prohibits possession based on regular use of substances like marijuana without showing current impairment or individualized risk.
The decision is narrow. It does not strike down the entire statute. Prohibitions can still apply to individuals proven to be addicted, presently intoxicated while possessing a firearm, or in circumstances demonstrating specific danger to others. The Court focused on the facts presented in Hemani’s case.

Impact for Ohio residents
Ohio voters approved recreational cannabis for adults 21 and older through Issue 2 in November 2023. Many residents now use marijuana legally under state law while also owning firearms. This Supreme Court ruling reduces the likelihood of federal felony charges based solely on regular marijuana use combined with gun possession.
Ohio gun owners and cannabis consumers should still exercise caution. Federal law continues to classify marijuana as a Schedule I controlled substance. Possessing or using a firearm while impaired by marijuana or any other substance remains risky and potentially unlawful. The ruling addresses criminal prosecution under this specific provision. It does not automatically change all aspects of federal background checks or purchase forms, though it signals limits on broad categorical enforcement.
Ohio maintains its own firearms laws, which operate separately from federal rules. Residents must comply with both. Some states, including Ohio, had supported the broader federal position in friend-of-the-court filings emphasizing public safety, but the Supreme Court reached a different conclusion on the constitutional question presented.
Gun rights organizations and cannabis advocacy groups praised the outcome. Public safety advocates had raised concerns about access to firearms by individuals who use controlled substances.
Practical advice for central and southern Ohio residents
Anyone with questions about their individual circumstances should consult a qualified attorney experienced in both federal firearms law and Ohio controlled substances regulations. This area of law involves overlapping state and federal rules that can change. Reliable, case-specific guidance is the best way to ensure compliance.
