Answered by a Former DEA Diversion Enforcement Counsel.
Jani Law PLLC can answer all of your questions about DEA enforcement actions. Attorney Dhairya Jani spent years as a DEA Diversion Enforcement Counsel and has firsthand experience of what registrants must do when facing enforcement actions.
These are common questions that registrants ask when something has gone wrong, or when they suspect it might. The answers reflect how these proceedings actually work.
An Order to Show Cause is the formal document that initiates DEA administrative proceedings to revoke an existing DEA registration or deny a pending DEA registration application. It sets out the government’s factual and legal basis for the action and starts a strict 30-day clock within which the registrant must request a hearing before a DEA Administrative Law Judge. If that window closes without a timely hearing request, all allegations in the OSC are treated as true and the DEA may move forward without a hearing.
By the time an OSC is served, the DEA’s investigation has typically been underway for months. The government’s record is already substantially built. Yours needs to be built to the same standard, starting the moment you receive it.
Call a DEA regulatory defense attorney today, not this week. The 30-day deadline to request a hearing before a DEA Administrative Law Judge runs from the date the OSC was served. If that window closes without a timely hearing request, all allegations are treated as true and the DEA may move forward without a hearing.
Yes. If you do not request a hearing within 30 days of being served with an Order to Show Cause, all allegations are deemed admitted by operation of law. The DEA Administrator may then revoke your registration without any further process. No hearing. No opportunity to present your side of the record.
This is one of the most consequential deadlines in federal administrative law. Missing it is not a procedural technicality. It ends the case.
An Immediate Suspension Order (ISO) is an emergency action that suspends a DEA registration the moment it is served, before any hearing takes place. The DEA issues an ISO when it concludes that continued registration poses an imminent danger to public health or safety. Everything stops the moment an ISO is served: prescribing, dispensing, ordering, receiving controlled substances. Non-compliance creates criminal exposure on top of the administrative proceeding.
An ISO can be challenged in federal district court while the administrative proceeding runs concurrently. Both tracks require same-day action. If you have been served with an ISO, call counsel immediately.
Same-day action is not optional. You can request an expedited administrative hearing and challenge the ISO in federal district court while the Order to Show Cause proceeding runs concurrently. Both tracks move fast and require immediate attention.
Handling either the ISO challenge in district court, or the Order to Show Cause administrative proceeding in front of a DEA administrative law judge, generally requires experienced counsel to navigate both tracks.
Stay calm. Ask to see credentials and identify the legal authority for the visit.
DEA investigators conduct routine inspections as well as targeted enforcement visits. You may ask clarifying questions. Before finalizing or signing any documents, you may request to speak with an attorney.
Being professionally cooperative and getting counsel on the phone at the earliest opportunity are not in conflict. Every interaction without counsel creates risk. Contact DEA defense counsel as soon as possible.
No. The earlier counsel is engaged, the more options you preserve. By the time an Order to Show Cause or Immediate Suspension Order arrives, an investigation has typically been running for months and the government’s record is already substantially developed.
Early engagement, before formal action, allows for strategic positioning. If you have any indication that the DEA may be looking at your practice or business, that is the right time to call.
More than most registrants realize, and it starts earlier than they expect. DEA investigators routinely access:
- ARCOS distribution data to analyze purchasing patterns
- State Prescription Drug Monitoring Program prescription records
- Patient overdose and death investigation files
- Suspicious order reports from distributors
- State licensing board complaint histories
- Tips from patients, employees, and colleagues
The DEA can also examine prescribing or dispensing patterns for outliers, review controlled substance combinations associated with diversion, and analyze documentation quality, all before making first contact with you. By the time a subpoena or inspection arrives, the investigative picture is already well-developed.
Technically yes. Practically, this is rarely advisable.
Every statement you make, every document you produce, and every position you take without counsel becomes part of the enforcement record, which is available to the DEA, civil enforcement attorneys, state licensing boards, and potentially federal prosecutors.
Without counsel, registrants often make statements or produce documents that shape the investigation in ways they did not intend and cannot undo. The cost of a misstep before retaining counsel is typically far greater than the cost of counsel itself.
It may trigger a parallel state proceeding. State medical, pharmacy, osteopathic, and veterinary boards sometimes initiate their own proceedings when they learn of a DEA investigation or enforcement action. The board may act on the same factual record, using documents produced and positions taken in the federal proceeding as evidence in the state forum.
A state board can suspend or revoke your professional license independently of the federal outcome and often does not wait for it. Both proceedings must be coordinated from the outset. What you do in one affects the other.
A Memorandum of Agreement (MOA) is a negotiated resolution that allows a registrant to avoid formal revocation proceedings in exchange for agreeing to specific compliance obligations. An MOA typically includes reporting requirements, compliance milestones, operational restrictions, and audit obligations lasting two to five years. It becomes a permanent part of your enforcement history and can serve as the basis for a new enforcement action if its terms are violated.
The terms of an MOA are not standardized. They are negotiable. What appears manageable on paper can create significant operational burdens in practice. Before you sign anything the DEA puts in front of you, have a DEA defense attorney review every term.
Not without experienced counsel reviewing every term.
An MOA is a regulatory probation, and the terms are not standardized. Reporting requirements, compliance milestones, operational restrictions, and duration all vary and are negotiable. Provisions that appear manageable in the abstract can create substantial operational burdens, constrain the business for years, and, if violated, provide the basis for a new OSC.
The MOA becomes part of your permanent enforcement history. Before you sign anything the DEA puts in front of you, have a DEA regulatory defense attorney review it.
DEA’s traditional enforcement standard is not a subjective good-faith standard. Under 21 C.F.R. § 1306.04(a), a controlled substance prescription is valid only if issued for a legitimate medical purpose by a practitioner acting in the usual course of professional practice. The same regulation places a corresponding responsibility on the pharmacist who fills the prescription to ensure its validity.
DEA evaluates compliance through its own experts, reviewing patient files prescription by prescription against what the government alleges is the applicable standard of care. DEA experts look for documentation gaps, missing Prescription Drug Monitoring Program queries, absent clinical rationale, and prescribing combinations the government associates with diversion. Good intent does not substitute for a documented record that supports each clinical decision.
Historically, the DEA applied an objective standard in pharmacy enforcement cases: a pharmacist could be held responsible not only for prescriptions they actually knew were invalid, but for prescriptions they had reason to know were invalid based on observable red flags. This “knew or had reason to know” standard placed a heavy burden on pharmacists to independently evaluate every prescription before filling it, regardless of whether the prescribing physician had a valid DEA registration and license.
That framework is now being tested in the courts. In February 2026, the Fifth Circuit vacated a DEA deregistration order in Neumann’s Pharmacy, L.L.C. v. Drug Enf’t Admin., 2026 WL 411942 (5th Cir. Feb. 13, 2026), holding that § 1306.04(a) requires the government to prove that a pharmacist actually knew a prescription was invalid, rejecting the longstanding objective standard. The court also held that acting outside the usual course of professional practice means something closer to abandoning the pharmacist’s role entirely, not merely falling short of state-law care standards. That decision is currently binding only in the Fifth Circuit and addresses pharmacy rather than prescriber liability, but its reasoning on the knowledge element has broader implications for how the DEA’s enforcement framework will be tested going forward.
In any jurisdiction, good intent alone does not substitute for a documented record that supports each clinical decision. But intent, knowledge, and the adequacy of the DEA’s legal theory are now all live issues in these proceedings. Building the complete counter-record and identifying where the government’s legal and factual theories are vulnerable is what DEA defense counsel is positioned to do.
Possibly Yes. DEA administrative proceedings evaluate whether the documented record, presented within the analytical framework that the Administrative Law Judge and DEA Administrator apply, supports continued registration as consistent with the public interest. Good faith and clinical accuracy are not irrelevant, but they must be translated into a record that satisfies the evidentiary and legal standards that actually govern the proceeding.
Registrants who believed they acted appropriately have still lost their registrations because the record was incomplete, the response was inadequately framed, or the proceeding moved faster than anticipated. The legal standards governing these proceedings are also not static. Recent federal court decisions, including the Fifth Circuit’s 2026 ruling in Neumann’s Pharmacy, L.L.C. v. Drug Enf’t Admin., 2026 WL 411942 (5th Cir. Feb. 13, 2026), have begun to examine whether the DEA’s enforcement framework accurately reflects what its regulations actually require. Identifying where the government’s legal theory is vulnerable, not just building the factual record, is now an essential component of DEA regulatory defense. The government’s case is built before the OSC is served. Yours needs to be built to the same standard.
