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] This rule change directly affects the federal firearms eligibility of millions of Americans -- including New York gun owners -- by narrowing when a person's drug use disqualifies them from possessing firearms under 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 a list of "inference" examples under which a person could be classified as an unlawful user -- including a single failed drug test, a single drug-related arrest or conviction, or a single admission of use within the past year. The new rule eliminates those inference 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 automatically disqualifies an individual from firearms possession. The ATF determined that classifying individuals as prohibited persons on the basis of a single unlawful use is inconsistent with ATF practice, the weight of court decisions over the past 20 years, and potentially unconstitutional under the Second Amendment.^[3]

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] This creates two distinct paths to disqualification: regular ongoing use (unlawful user) and compulsive use with impaired control (addicted).

What Did Not Change: Cannabis Remains Federally Prohibited

The revised rule does not exempt marijuana users from the firearms prohibition. Cannabis remains a Schedule I controlled substance under federal law, and current, regular marijuana users remain prohibited persons under 922(g)(3) regardless of whether their state has legalized cannabis.^[1] This distinction is critical for New York gun owners because New York legalized recreational cannabis in 2021 through the Marijuana Regulation and Taxation Act (MRTA). A New Yorker who uses cannabis lawfully under state law but does so regularly and on an ongoing basis is still federally prohibited from possessing firearms or ammunition.

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.

For New York gun owners who use cannabis, the practical reality remains unchanged: regular, current marijuana use -- even use that is entirely lawful under New York state law -- continues to disqualify a person from possessing firearms under federal law. The narrowed ATF definition may provide relief only to individuals whose past drug use was limited, isolated, and not continuing into the present.

U.S. v. Hemani: The Supreme Court Weighs In

The constitutionality of Section 922(g)(3) itself is currently before the U.S. Supreme Court in United States v. Hemani. The Court heard oral arguments on March 2, 2026, in a case challenging whether the federal prohibition on firearms possession by unlawful users of controlled substances violates the Second Amendment as applied to marijuana users.^[4] The Department of Justice filed a brief urging the Court to uphold the ban, but several justices appeared skeptical during oral arguments.^[5]

If the Court strikes down 922(g)(3) as applied to cannabis users, the conflict between New York's cannabis legalization and federal firearms law could be resolved -- at least partially. A decision is expected by the end of the Court's current term in June 2026.

Interim Final Rule Status

The ATF rule is an interim final rule, meaning it took effect immediately on January 22, 2026, but is subject to a public comment period through June 30, 2026.^[2] The ATF may revise the rule based on comments received. Gun owners and attorneys should monitor both the rulemaking process and the Hemani decision for developments that may further change this area of law.
