Nurses are among the most trusted professionals in the healthcare system. Patients, employers, and licensing boards rely on them to administer medications safely, accurately, and ethically. When a nurse is accused of diverting drugs, that level of trust can be called into question almost immediately.
A drug diversion allegation is one of the most serious accusations that a California nurse can face from the California Board of Registered Nursing (BRN). In addition to potentially losing your nursing license, if you are accused of drug diversion, it could lead to termination and criminal prosecution. Seeking legal counsel immediately is the best way to protect your license, your livelihood, your reputation, and your freedom.
At the Law Office of Nicole Irmer, we take a multi-pronged approach to professional license defense. Our goal is to resolve disciplinary issues outside of the formal process whenever possible, while preparing for an administrative hearing if necessary.

Drug diversion occurs when prescription medications intended for patients are diverted for unauthorized use. In healthcare settings, diversion may involve controlled substances such as morphine, fentanyl, hydromorphone (Dilaudid), oxycodone, hydrocodone, ketamine, benzodiazepines, or other scheduled medications.
Drug diversion allegations can include claims that a nurse:
Because controlled substances are heavily regulated, even relatively small discrepancies may trigger an investigation into potential drug diversion.
The California Board of Registered Nursing (BRN) typically does not discover diversion allegations on its own. Instead, investigations usually begin after a complaint or mandatory report.
Common sources of complaints of drug diversion include:
If an employer suspects diversion, it may conduct an internal investigation before reporting the matter to the BRN.
These reports frequently become the basis for BRN investigations.
While these observations do not necessarily prove diversion, they often prompt further investigation.
Many diversion cases begin long before the BRN gets involved. Employers often investigate suspected drug diversion quietly while continuing to gather evidence.
Internal investigations may include:
Some nurses are asked to attend meetings with supervisors or human resources representatives. These meetings may seem informal, but they should be taken seriously. Everything that a nurse says may later appear in investigation reports submitted to the BRN or prosecutors. If your employer is investigating possible drug diversion, it is a good idea to consult with a California nursing license defense attorney early in the process.
If the BRN receives a complaint about possible drug diversion or another violation of the Nursing Practice Act (NPA), it does not automatically discipline the nurse. Instead, the BRN will open an investigation to determine if a violation occurred and disciplinary action is warranted.
This investigation often includes multiple steps:
The investigation can continue for many months.
One of the biggest mistakes nurses make after a diversion allegation is agreeing to answer questions before obtaining legal advice. Many nurses believe that if they cooperate or feel that they have nothing to hide, it isn’t a big deal. Unfortunately, this type of assumption can have serious consequences.
Statements made during licensing investigations often become evidence in administrative hearings. If criminal charges are later filed, prosecutors may also seek access to those statements. A seemingly harmless explanation for what may have happened can later be portrayed as an admission.
BRN investigators are not advocates for the nurse. Their role is to gather information for the BRN to determine whether disciplinary action is warranted. This means that they’re collecting evidence, not necessarily protecting the nurse’s interests or trying to help a nurse.
Investigators rarely disclose everything they know before asking questions. A nurse may unknowingly make statements that conflict with documentation, witness accounts, or electronic records. Any inconsistency can significantly weaken a nurse’s credibility and ultimately defense.
An experienced California professional license defense attorney can:
Having legal representation does not imply guilt. Instead, it helps to ensure that important decisions are made with a full understanding of the potential legal consequences.
Drug diversion allegations may result in both licensing discipline and criminal prosecution. These are separate legal proceedings with different standards and potential consequences.
Depending on the facts of a case, a prosecutor could charge a nurse with:
Even if the BRN has not completed its investigation, prosecutors may independently pursue criminal charges. In many situations, the administrative licensing and criminal cases move forward at the same time. That is why it is so important to work with an attorney who can represent you in both professional licensing and criminal defense matters.
Each case is unique. The outcome of any case will depend on numerous factors. This may include the strength of the evidence, any prior disciplinary history, whether patients were harmed, the outcome of criminal cases, rehabilitation efforts, mitigating circumstances, and cooperation during the investigation.
Potential outcomes for a drug diversion allegation include:
The BRN does offer an intervention program for nurses with substance abuse and/or mental health issues. While there are upsides to the intervention program, there are also significant drawbacks. You should consult with a California nursing license defense lawyer before agreeing to enter into an intervention program for a drug diversion allegation.
Drug diversion cases are often more complicated than they first appear. Medication discrepancies may result from:
An effective defense requires careful review of the available evidence rather than simply making assumptions based on the initial accusations. Depending on the circumstances, the defense strategy may include:
Having experienced counsel is crucial to putting together a strong defense. Our law firm takes a proactive approach to professional licensing disciplinary matters, working hard to resolve our clients’ cases outside of the formal process whenever possible.

Because these cases often involve both BRN disciplinary proceedings and the possibility of criminal prosecution, every decision made early in the process can have lasting consequences. Consulting with an experienced California professional license defense lawyer as soon as possible can increase the likelihood of a successful outcome.
