The US Supreme Court rules unanimously to narrow the federal law that bars firearm possession by certain illegal drug users. In the case, a Texas man is charged after FBI agents find a handgun in his home during a raid. The man admits he smokes marijuana about every other day and keeps the firearm for self-defense. The federal government prosecutes him under a statute prohibiting gun ownership by “unlawful users” of controlled substances. Writing for the Court, Justice Neil Gorsuch finds the government’s reading of the law is overly broad and violates the Second Amendment because it does not require an adequate link between drug use and dangerousness. The Court rejects the government’s reliance on older historical laws that restricted firearm rights for “habitual drunkards,” saying those laws addressed different people, for different reasons, under different conditions. The Court notes prosecutors do not allege the defendant is addicted, uses the firearm while intoxicated, threatens anyone, or poses a danger. It also points to changes in federal and state marijuana policies, including steps to reduce enforcement and move marijuana to a less restrictive schedule.
