GAO Highlights Vulnerabilities in DEA and FDA Drug Scheduling Processes
Although DEA and HHS scheduling decisions aligned completely between 2020 and 2025, a new GAO report warns that missing agency policies and an outdated 40-year-old interagency agreement threaten operational consistency across federal drug oversight and defense health supply chains.
A new Government Accountability Office (GAO) report reveals that while the Drug Enforcement Administration (DEA) and the Department of Health and Human Services (HHS) maintain strong technical alignment on controlled substance scheduling, severe institutional policy gaps threaten long-term operational continuity. Between 2020 and 2025, the DEA conducted scheduling actions for 208 substances under the Controlled Substances Act, incorporating HHS scientific and medical evaluations for all 95 instances where consultation was statutorily mandated. Of the 84 finalized rulemakings completed during this six-year period, DEA scheduling decisions achieved a 100 percent alignment rate with HHS recommendations, with the remaining 11 substances maintained under active temporary scheduling orders.
Despite this surface-level harmony, the GAO uncovered critical governance deficiencies across participating agencies. The DEA currently lacks formalized internal policies outlining clear roles, responsibilities, and procedural benchmarks for executing scheduling determinations. Similarly, the Food and Drug Administration (FDA) operates without standardized written protocols governing how its scientific personnel conduct medical evaluations or formulate drug risk recommendations. Compounding these internal vulnerabilities, the foundational Memorandum of Understanding (MOU) establishing consultation protocols between the FDA and the National Institute on Drug Abuse (NIDA) has not been updated in over four decades, failing to reflect modern interagency structures, research methodologies, or administrative workflows.
