Supreme Court Shocks: Pot, Guns, and Power

The Supreme Court just ruled that the federal government cannot strip gun rights from occasional marijuana users — and Justice Clarence Thomas went even further, arguing Congress never had the power to pass the law in the first place.

Quick Take

The Supreme Court ruled unanimously in United States v. Hemani that banning occasional marijuana users from owning guns violates the Second Amendment.
Justice Clarence Thomas agreed with the ruling but added that Congress lacks the power under the Commerce Clause to ban gun possession based on drug use at all.
Thomas argues the Commerce Clause only lets Congress regulate the buying and selling of goods across state lines — not whether someone at home can own a firearm.
The federal government’s own “half-in, half-out” approach to marijuana enforcement has weakened its legal arguments, according to Thomas.

The Supreme Court Strikes Down a Federal Gun Ban

The Supreme Court ruled unanimously that the federal law banning “unlawful users” of drugs from owning firearms — known as 18 U.S.C. § 922(g)(3) — cannot be applied to occasional marijuana users. Justice Neil Gorsuch wrote for the Court that while habitual drug users who pose a real danger may still be disarmed, the government cannot assume every marijuana user is dangerous without proving it. The ruling is a major win for Second Amendment rights.

The case, United States v. Hemani, drew attention partly because the same federal law was used against Hunter Biden. The Court’s decision does not wipe out the entire statute. It leaves in place restrictions on people who are truly addicted or actively intoxicated. But it draws a clear line: the government must show an individual is actually dangerous before taking away their gun rights. A blanket ban based on drug use alone does not pass constitutional muster.

Thomas Goes Further: Congress Overstepped Its Authority

Justice Thomas joined the majority opinion but wrote separately to raise a bigger question. He argued that Congress never had the authority to pass this gun ban in the first place. His reasoning centers on the Commerce Clause — the part of the Constitution that lets Congress regulate trade between states. Thomas says that power only covers the buying and selling of goods across state lines, not what a person does with a firearm inside their own home. ^[3]

Thomas has made this argument before. Back in 2005, he dissented in Gonzales v. Raich, warning that if Congress can regulate homegrown marijuana under the Commerce Clause, “then it can regulate anything — and the Federal Government is no longer one of limited and enumerated powers.” ^[4] In his view, the Framers built the Constitution to prevent exactly this kind of federal overreach. Letting Washington control local gun possession under the guise of commerce regulation is a step too far.

A “Half-In, Half-Out” Federal Policy That Undermines Itself

Thomas also pointed out that the federal government’s own marijuana policies have become a legal mess. Dozens of states now allow medical or recreational marijuana, yet federal law still treats it as fully illegal. Thomas called this a “half-in, half-out regime that simultaneously tolerates and forbids local use of marijuana.” ^[4] That contradiction, he argued, makes it even harder for the government to justify sweeping gun bans tied to marijuana use.

SCOTUS Rules Gun Restriction On Unlawful Drug Users To Be ‘Inconsistent’ With Second Amendment

Why do we have the question about drug use on firearm questionnaires then?🤔

On one hand I am glad SCOTUS is taking 2A rights seriously, but am confused as to why that question was… pic.twitter.com/cxdtd9QgaT

The ruling fits a broader pattern at the Supreme Court. Since District of Columbia v. Heller in 2008 confirmed that gun ownership is an individual right, and since New York State Rifle & Pistol Association v. Bruen in 2022 required the government to show a historical tradition before restricting guns, federal courts have faced thousands of Second Amendment challenges. ^[13] The government keeps losing when it cannot point to a clear historical parallel for its restrictions — and in this case, it could not. The Constitution means what it says, and the Court is finally holding the government to that standard.
