ATF 2026 Rule Change: Drug User Definition and New York Impact

On January 22, 2026, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) published an interim final rule revising the definition of "unlawful user of or addicted to any controlled substance" in 27 CFR 478.11.^[1] The rule narrows the regulatory definition and removes single-incident inference examples. It creates no new prohibition and does not change 18 U.S.C. 922(g)(3).

What Changed

Under 18 U.S.C. 922(g)(3), it is unlawful for any person who is "an unlawful user of or addicted to any controlled substance" to possess firearms or ammunition.^[2] The ATF's previous regulatory text included inference examples such as a conviction for use or possession within the past year, multiple arrests within five years when the most recent occurred within the past year, a failed drug test within the past year, and specified military actions based on confirmed drug use. The new rule removes those examples and replaces them with a more specific definition.

Revised "Unlawful User" Definition

Under the new rule, "unlawful user" means a person who regularly uses a controlled substance over an extended period of time continuing into the present, without a lawful prescription or in a manner substantially different from that prescribed by a licensed physician.^[1] A single past incident of drug use no longer establishes unlawful-user status under the regulation. ATF explained that a single incident did not reflect its enforcement practice, conflicted with the weight of recent decisions, and raised constitutional concerns.^[1]

Separate "Addicted" Definition

The rule also separately defines "addicted" as a person who uses a controlled substance and demonstrates a pattern of compulsively using the substance, characterized by impaired control over use.^[1] These are the two distinct regulatory definitions ATF uses when applying Section 922(g)(3).

Cannabis Scheduling After the April 2026 Rules

Federal scheduling now depends on the product and regulatory setting. An April 28, 2026 final rule placed FDA-approved drug products containing marijuana and marijuana subject to a state medical-marijuana license in Schedule III. Marijuana outside the categories covered by that rule generally remains in Schedule I while a broader rescheduling proceeding continues.^[3]

Scheduling alone does not determine the outcome of every firearms case. Section 922(g)(3) applies to an unlawful user of or person addicted to a controlled substance, and the Supreme Court has limited how the unlawful-user provision may be applied under the Second Amendment.

Impact on New York Gun Owners

New York's firearms licensing system under Penal Law Section 400.00 incorporates federal disqualifiers, including 922(g)(3), as part of the eligibility determination for pistol permits and concealed carry licenses. When an applicant answers "yes" to the question about controlled substance use on ATF Form 4473, or when a background check reveals information suggesting unlawful use, the revised ATF definition determines whether that use rises to the level of a disqualifying prohibition.

After the April 2026 scheduling rules and Hemani, regular marijuana use cannot be described as an automatic federal firearms disqualification in every case. The analysis depends on whether the use is unlawful under current federal rules, whether the person meets ATF's current definitions, and whether the government can constitutionally apply Section 922(g)(3) on the specific facts. A person should not rely on state legality alone when completing Form 4473 or evaluating possession.

United States v. Hemani: The June 2026 Decision

The Supreme Court decided United States v. Hemani on June 18, 2026. The government relied solely on Hemani's regular marijuana use, which occurred a few times each week. The Court held that prosecuting him under the unlawful-user provision was inconsistent with the Second Amendment. The decision does not address bans involving addiction or present intoxication, or a prosecution supported by individualized proof that a person's drug use makes that person dangerous.^[4]

Interim Final Rule Status

The January 22, 2026 interim final rule took effect immediately, and its public comment period closed on June 30, 2026.^[2] ATF may revise the regulatory definition after reviewing comments. The April scheduling rules and the Supreme Court's Hemani decision must also be considered when evaluating current law.
