Comment on FR Doc # 2026-01141

Bureau of Alcohol, Tobacco, Firearms, and Explosives, Docket No. ATF-2026-0034; RIN 1140-AB03. As a person interested in the regulatory processes that govern firearm eligibility, I am writing to provide comments regarding the interim final rule published by the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) to revise the definition of "unlawful user of or addicted to any controlled substance." The proposed changes seek to align agency regulations with a body of judicial precedent that has increasingly emphasized the necessity of a "temporal nexus" and "regularity" of drug use to trigger the prohibition found in 18 U.S.C. 922(g)(3). By removing specific, arguably overbroad inference examples—such as those based on a single instance of drug use or possession—the rule intends to bring greater consistency between administrative background check outcomes and the legal interpretations applied by federal courts. From a technical perspective, the effect of this rule is a shift from a bright-line, inference-based administrative standard to a more qualitative, case-by-case evaluation of whether an individual’s conduct constitutes "regular" use "over an extended period of time." This transition will likely alter the workflow for the National Instant Criminal Background Check System (NICS) examiners, who have historically relied upon the specific inference examples in 27 CFR 478.11 to make rapid determinations. By removing these benchmarks, the rule necessitates that agencies develop new operational guidance to determine what constitutes sufficient evidence of "regular and recent" use. This ensures that determinations are better grounded in the evidentiary requirements recognized by the circuits, but it also introduces a need for clear, standardized training for those tasked with enforcing these prohibitions to prevent inconsistent application across different jurisdictions. While the reduction in potentially erroneous denials is a significant outcome of this policy, it is worth considering the downstream implications of this transition. Moving away from clear, time-limited inference triggers may create ambiguity for both licensees and prospective purchasers who may now face uncertainty regarding how their past conduct is categorized under federal law. Furthermore, because this rule acts as an interpretive measure, it is critical that the agency provides robust, transparent guidance to the public regarding what evidentiary threshold will satisfy the new requirement of "regularity." Clarity on this front will be essential to ensure that the regulatory environment remains predictable for all stakeholders. I encourage the agency to continue its efforts to develop clear, evidence-based standards that honor both the statutory intent of the Gun Control Act and the constitutional interests of the public.
