Section 922(g)(3): Unlawful Drug Users, Firearm Bans, and the Second Amendment

Federal law prohibits firearm possession by any person who is an unlawful user of or addicted to a controlled substance. That provision—18 U.S.C. § 922(g)(3)—has become a major post-Bruen battleground. United States v. Hemani (2026) is among the ultra-recent decisions testing the statute; because 2026 slip opinions may not yet be reliably present in every case corpus, cite Hemani (2026) in plain text and build the research spine from New York State Rifle & Pistol Ass’n v. Bruen, 597 U.S. 1 (2022), United States v. Rahimi, 602 U.S. 680 (2024), and District of Columbia v. Heller, 554 U.S. 570 (2008).

Background: status-based prohibitions after Bruen

Bruen requires the government to justify firearm regulations with historical tradition once plain text covers the conduct. Status-based bans—felons, fugitives, unlawful drug users, persons under certain restraining orders—raise recurring questions: Who counts as outside the “people” protected by the Amendment? Alternatively, if the person is covered, what historical analogues justify disarmament?

Heller itself noted that nothing in its opinion should cast doubt on longstanding prohibitions on firearm possession by felons and the mentally ill, or laws forbidding firearms in sensitive places and imposing conditions on commercial sales. McDonald repeated those assurances in the incorporation context: McDonald v. City of Chicago, 561 U.S. 742 (2010). Bruen then changed the method lower courts must use to test modern statutes. Rahimi showed that a modern domestic-violence restraining-order ban can fit a tradition of disarming dangerous persons.

What the governing precedents establish

Bruen’s rule remains the screen:

If the Second Amendment’s plain text covers an individual’s conduct, the Constitution presumptively protects it, and the government must demonstrate that its regulation is consistent with the Nation’s historical tradition of firearm regulation.

Rahimi’s application supplies the closest Supreme Court template for status-based disarmament:

The Second Amendment permits the government to disarm individuals who present a credible threat to the physical safety of others when the prohibition fits within historical tradition, as § 922(g)(8) does for qualifying restraining orders.

§ 922(g)(3) litigation asks whether unlawful drug use or addiction is relevantly similar—whether history supports disarming persons whose status is thought to indicate danger, impairment, or unreliability with firearms, and how narrowly the statute must be construed (active use versus remote past use, addiction versus occasional unlawful use, marijuana’s changing state-law status, and so on). Hemani (2026) should be read for those particulars in plain text, then compared line-by-line to Rahimi’s danger-and-process logic and Heller’s illustrative limits.

Why it matters

Drug-user prohibitions affect millions of potential defendants and civil possessors, including in states that have legalized cannabis under state law while federal prohibition remains. Second Amendment challenges therefore carry both criminal-procedure and regulatory consequences. Researchers must track not only merits doctrine but also scienter, definitional regulations, and as-applied records (timing of use, type of substance, nexus to possession).

Keep neighboring cases in their lanes. Public-carry and sensitive-place disputes—including Wolford v. Lopez (2026), citeable in plain text—concern where arms may be borne, not who is categorically barred. Speech-platform cases such as Moody v. NetChoice (2024) or Counterman v. Colorado, 600 U.S. 66 (2023) do not decide § 922(g)(3); mention them only for interdisciplinary contrast. Reed v. Town of Gilbert, 576 U.S. 155 (2015) likewise is a First Amendment content-neutrality case, useful at most as methodological contrast.

Practical takeaways

• Frame § 922(g)(3) memos as Bruen text-and-history analyses, with Rahimi as the leading status-ban analogue.
• Cite United States v. Hemani (2026) in plain text until a stable opinion link exists; deeply link Bruen, Rahimi, Heller, and McDonald.
• Develop facts on recency and nature of drug use; as-applied challenges often turn on status breadth.
• Separate “who may possess” questions under § 922(g) from “where may one carry” sensitive-place questions.
• Use Heller’s list of presumptively lawful regulations as persuasive context, not as a substitute for Bruen’s historical showing.
• Watch federal-state marijuana conflicts as statutory and practical overlays, not as automatic Second Amendment answers.

Frequently asked questions

What is 18 U.S.C. § 922(g)(3)?

It is the federal prohibition on firearm possession by any person who is an unlawful user of or addicted to a controlled substance.

How should researchers cite United States v. Hemani (2026)?

Cite Hemani (2026) by name and year in plain text when corpus links are unreliable, and anchor the doctrine with linked Bruen, Rahimi, Heller, and McDonald precedents.

Does Rahimi automatically uphold § 922(g)(3)?

Not automatically. Rahimi upholds a different subsection keyed to judicial findings of interpersonal danger. § 922(g)(3) requires its own historical-tradition comparison under Bruen.
