Compliance with statutes and regulations enforced by the Drug Enforcement Administration (DEA) is not optional – nor is it theoretical. DEA audits of veterinary clinics are now common nationwide, and when violations are identified, the consequences can be severe. These may include monetary fines, suspension or revocation of DEA registration, loss of licensure, and, perhaps most damaging of all, irreparable reputational harm to the practice and the veterinarian.

In my experience, DEA violations in veterinary practices are rarely intentional. Instead, they typically arise from preventable operational blind spots, inconsistent documentation, informal habits that replace written procedures, or inadequate staff training. Understanding the most common compliance failures – and how to proactively avoid them – can significantly reduce regulatory risk and protect both the practice and the DEA registrant.

The Most Common Mistakes and How to Safeguard Compliance

Recordkeeping
Incomplete/inconsistent controlled‑substance logs are the most common issue identified during DEA inspections. These errors include missing or delayed entries, incomplete documentation, or logs that do not reconcile with physical inventory. Poor documentation alone can result in fines. The DEA requires accurate, real‑time records for the receipt, dispensing, administration, and inventory of controlled substances. Therefore: a) maintain meticulous, real-time controlled substance logs which should be completed at the time of receipt, dispensing, or administration. Any discrepancy should be investigated immediately; and b) every DEA registrant must complete an initial controlled‑substance inventory and a biennial inventory and document these properly. Best practice: inventory at least monthly – if not more frequently – so discrepancies are identified and addressed as soon as practicable.

Storage and Security
Controlled substances must be stored in a securely locked, substantially constructed cabinet or safe. Best practice: a safe dedicated solely to controlled substances should be immovable without detection, surveillance cameras should monitor access points, and video footage should be retained for at least one year – ideally for a rolling three‑year period. Inspectors frequently cite practices where drugs are left in unlocked drawers, unsecured treatment areas, or locations accessible to non‑authorized staff.

Excessive or Uncontrolled Staff Access
Allowing too many employees to access controlled substances significantly increases diversion risk. Clear ownership and responsibility empower staff to safeguard inventory and allow practices to identify how discrepancies occur – and who may be responsible. Therefore, a) strictly control and maintain records of which staff members have access and hold those individuals accountable; b) limit keys or access codes to the smallest number of authorized personnel necessary to operate efficiently; c) conduct internal audits quarterly or monthly to identify discrepancies early and d) implement two-person verification when controlled substances are received and during inventory counts to reduce errors and deter diversion.

Registration Lapses or Address Errors
DEA registrations must be renewed timely and must reflect the exact physical location where controlled substances are stored. Failure to update a registration following a move, renovation, or expansion is a violation – even if no diversion has occurred.   Some simple advice: set calendar reminders well in advance of DEA renewal deadlines. Confirm that registration details – including addresses – accurately reflect where controlled substances are stored and used.

Improper Disposal or Wastage Documentation
Expired, damaged, or unused controlled substances must be disposed of using approved methods. Informal disposal, undocumented wastage, or retaining expired drugs “just in case” exposes practices to enforcement action. Partner with a licensed reverse distributor for expired or unwanted controlled substances. Document all wastage and destruction thoroughly, including witness signatures when required.

Failure to Report Loss or Theft Promptly
Any theft or significant loss must be reported using DEA Form 106. Delays in reporting while conducting internal investigations may themselves be considered non‑compliance. Therefore, if a loss or theft is suspected, secure remaining inventory and file DEA Form 106 within 24 hours – even if the investigation is ongoing. Prompt reporting demonstrates good faith compliance and transparency.

Lack of Written Policies and Training
Many practices operate on habit rather than formal policy. It is best to have written standard operating procedures which address storage, inventory, dispensing, wastage, audits, and incident response. Annual (if not more frequent!) training ensures staff understand both legal obligations and internal expectations.

Conclusion
DEA compliance is not about perfection – it is about diligence, documentation, and consistency. Treat controlled‑substance management as a core operational function rather than an afterthought, and your practice will be far better positioned to withstand audits and avoid enforcement actions. A proactive approach protects not only the practice, but also the veterinarian’s license, reputation, and livelihood. If your practice has not reviewed its controlled‑substance policies recently, do it now-before the DEA does it for you.
