- What it's about
The Supreme Court held that 18 U.S.C. §922(g)(3), which bars gun possession by anyone who is an unlawful user of or addicted to a controlled substance, violated the Second Amendment as applied to Ali Danial Hemani, who admitted regularly using marijuana and kept a gun in his home. The Court concluded the government had not shown a historical tradition of disarming people like Hemani based only on regular drug use, without proof of intoxication, dangerousness, or a similar legal process.
Question presented
Does a federal law that prohibits the possession of firearms by a person who “is an unlawful user of or addicted to any controlled substance” violate the respondent’s Second Amendment right to bear arms?

Briefing
What it's about
The Supreme Court said the federal law in 18 U.S.C. §922(g)(3) could not be applied to Ali Danial Hemani, who admitted regularly using marijuana and kept a gun in his home. The justices said the government had not shown a historical tradition for disarming someone like him based only on regular drug use.
Vote
Impact
The decision limits how the federal government can use this gun ban in cases built only on regular drug use. For example, a person accused under §922(g)(3) may now argue the law cannot be used against them without proof of intoxication, dangerousness, or a similar legal process.
What's next
Lower courts must apply this ruling in similar Second Amendment challenges to §922(g)(3). Federal prosecutors and agencies enforcing gun laws will need to review pending cases and decide whether their evidence goes beyond regular drug use alone.
What was the main dispute in United States v. Hemani?
The case asked whether the federal gun ban for unlawful drug users could be applied to Hemani without violating the Second Amendment.
What are the real-world consequences of this decision?
People charged under §922(g)(3) may cite this case when the government relies only on regular drug use, not intoxication or proven danger.
What happens next after the Supreme Court's decision?
Lower courts must follow this ruling in similar cases. Prosecutors must review pending cases and decide whether their evidence shows more than regular drug use.
Decision
What the Court decided
The Court said the government could not strip Hemani of his gun rights under this law based only on his regular marijuana use.
Impact
This affects people prosecuted under §922(g)(3) for gun possession based only on regular drug use. For them, the federal government cannot automatically take firearm rights without showing incapacitation, dangerousness, or violence risk. Example: Hemani admitted using marijuana about every other day and kept a gun at home. Next, similar cases may test whether prosecutors can enforce this law without individualized proof (person-specific evidence). The ruling also pressures the government to find historical laws closely matching modern gun restrictions.
