Executive Order 12564: Federal Drug Testing Rules and Rights

Executive Order 12564, signed by President Ronald Reagan on September 15, 1986, is the order that declared illegal drug use incompatible with federal employment and required every executive branch agency to build a drug-free workplace program with testing, counseling, and discipline.¹ Nearly four decades later, it remains the legal backbone of federal employee drug testing, even as the drugs on the panel, the specimen types, and the scheduling of some substances have changed.

Section 1 states plainly that people who use illegal drugs “are not suitable for Federal employment.” That language gives agencies broad authority to act on any confirmed use, whether or not the employee was impaired at work.¹ The rest of the order lays out who gets tested, when, how, and what happens after.

Who the Order Covers

Section 7(b) applies the order to executive agencies as defined in 5 U.S.C. 105, which includes executive departments, government corporations, and independent establishments.² It also reaches the uniformed services other than the armed forces.

Three federal employers sit outside the order: the United States Postal Service, the Postal Rate Commission (now the Postal Regulatory Commission), and employing units in the judicial and legislative branches.³ Those entities may run their own drug policies, but EO 12564 does not compel them.

Sensitive Positions and Mandatory Testing

The order draws a sharp line between general federal employees and those in “sensitive positions.” Employees in sensitive roles face mandatory drug testing; everyone else falls under a voluntary framework unless a specific trigger applies. Section 7(d) defines a sensitive position as any of the following:¹

Positions an agency head designates as Special Sensitive, Critical-Sensitive, or Noncritical-Sensitive.
Employees who hold or may be granted access to classified information.
Anyone serving under a Presidential appointment.
Law enforcement officers as defined in 5 U.S.C. 8331(20).
Other roles the agency head determines involve law enforcement, national security, protection of life and property, public health or safety, or functions requiring a high degree of trust and confidence.

That last category is intentionally broad. Each agency head decides which specific jobs qualify, and the criteria can sweep in positions employees do not think of as “sensitive.” Scope, frequency, and selection for random testing within those positions are also left to the agency head, based on mission and the risk to public safety if an employee were impaired.¹

When Testing Can Happen

Section 3 sets out the circumstances that trigger a test. Random testing of sensitive-position employees is the most visible, but it is not the only one.

Random testing for employees in sensitive positions, on terms the agency head sets.
Reasonable-suspicion testing of any employee when there is a reasonable basis to believe the person uses illegal drugs. This typically requires a supervisor to observe and document specific physical or behavioral indicators such as slurred speech, unsteady movement, or a noticeable pattern of declining performance.
Post-accident or unsafe-practice testing, regardless of whether the employee holds a sensitive position.
Follow-up testing for employees who have gone through counseling or rehabilitation through the Employee Assistance Program.
Applicant testing as a condition of hiring, at the agency head’s discretion.

The order also authorizes voluntary testing for non-sensitive employees, either at their own request or through a program the agency establishes.¹

What the Test Screens For

Section 7(c) defines “illegal drugs” as any Schedule I or Schedule II controlled substance whose possession is unlawful, and it explicitly excludes substances used under a valid prescription or other legal authorization.¹ An employee taking a Schedule II painkiller with a valid prescription is not violating the order; the same drug without a prescription would qualify.

The Department of Health and Human Services, through the Substance Abuse and Mental Health Services Administration, sets the specific testing panels and cutoff concentrations. As of July 2025, the authorized federal panel screens for marijuana metabolites, cocaine metabolites, codeine and morphine, hydrocodone and hydromorphone, oxycodone and oxymorphone, heroin (6-acetylmorphine), phencyclidine (PCP), fentanyl, amphetamine and methamphetamine, and MDMA. Fentanyl was added relatively recently. Agencies can now collect either urine or oral fluid specimens; oral fluid testing was authorized under the same 2025 guidelines and uses different cutoff concentrations calibrated for saliva.⁴

Marijuana Is Still a Problem

In April 2026, the Justice Department and DEA moved FDA-approved marijuana products and marijuana products regulated under state medical licenses to Schedule III.⁵ Because EO 12564 defines illegal drugs as Schedule I or II substances, that rescheduling might look like an opening. It is not, in practice. Marijuana metabolites remain on the federal drug testing panel at the same cutoff concentrations.⁴ Recreational marijuana still involves substances whose possession is unlawful under federal law, and the broader rescheduling question is unresolved, with a further DEA administrative hearing scheduled for June 2026.

Federal law also does not require agencies to accommodate medical marijuana use. The Americans with Disabilities Act has been interpreted not to require accommodation of a substance that remains illegal under federal drug control law, even where state law authorizes it.

What Happens After a Positive Test

Section 5 governs the consequences, and this is where the order is misunderstood most often. It is not a straight escalation from warning to firing. It hinges on whether you cooperate with rehabilitation.

The first mandatory step is a referral to the Employee Assistance Program for assessment, counseling, and, where appropriate, treatment or rehabilitation. Every employee found to use illegal drugs gets this referral, regardless of position or how the use was detected.⁶

Beyond the referral, agencies must initiate some form of disciplinary action, with one important exception. Discipline is not required for an employee who voluntarily self-identifies as a drug user or volunteers for testing before being caught, obtains counseling through the EAP, and then stops using illegal drugs. All three conditions must be met.¹

For employees in sensitive positions, the order requires immediate removal from that role upon a finding of illegal drug use. They cannot return to sensitive duties until they have successfully completed rehabilitation, though the agency head has discretion to allow an earlier return if it would not endanger public safety or national security.¹

When Removal From Federal Service Becomes Mandatory

The order requires agencies to initiate removal proceedings against any employee who either refuses to obtain counseling or rehabilitation through the EAP, or does not stop using illegal drugs after going through the process.¹ That is a critical distinction from the common belief that a second positive test triggers automatic termination. The actual trigger is refusal to cooperate or continued use. An employee who tests positive once, completes rehabilitation, and stays clean may keep their job. An employee who tests positive once but refuses counseling faces removal regardless of how many tests were run.

How Results Can and Cannot Be Used

Preliminary results from an initial screen cannot be used in administrative proceedings unless confirmed by a second analysis of the same sample, or unless the employee admits to drug use. Positive results can be rebutted by other evidence showing the employee did not actually use illegal drugs. And drug testing conducted under this order cannot be used to gather evidence for criminal prosecution.¹

Your Rights Before Results Are Reported

Section 4(b) requires that before conducting a test, the agency inform the employee of the opportunity to submit medical documentation supporting a legitimate use for a specific drug.¹ Section 4(c) requires procedures for retesting, retention of records and specimens, and confidentiality of results and medical records.

A Medical Review Officer, a licensed physician, reviews laboratory results and evaluates whether there is a legitimate medical explanation for a positive, adulterated, substituted, or invalid test result.⁷ The MRO is an independent gatekeeper between the lab and the agency. Before any positive result is reported to the employer, the MRO contacts the employee to determine whether a valid prescription or other medical reason explains the finding. An employee taking legitimately prescribed oxycodone will initially produce a positive lab result; the MRO’s job is to verify the prescription and report the result as negative if the documentation checks out. Employees who fail to respond to the MRO’s outreach risk having the result reported as a confirmed positive by default.

Notice, Response, and Appeal Rights

Any removal or suspension lasting more than 14 days falls under the adverse-action procedures of 5 U.S.C. 7513. You are entitled to at least 30 days’ advance written notice of the specific reasons for the proposed action, at least 7 days to respond orally and in writing with supporting evidence, the right to be represented by an attorney, and a written decision with specific reasons at the earliest practicable date.⁸ The 30-day notice can be shortened if there is reasonable cause to believe the employee committed a crime that could result in imprisonment.

An employee who is removed or suspended can appeal to the Merit Systems Protection Board. The Board will generally review an initial decision only if it contains erroneous findings of material fact, rests on a misinterpretation of law, involved procedural errors that affected the outcome, or if new material evidence has surfaced that was previously unavailable despite the employee’s diligence.⁹

The MSPB has recognized meaningful defenses in drug cases. Section 5(f) explicitly allows rebuttal evidence, and where the Board has found that ingestion of an illegal substance was unknowing or unintentional, it has held that the appropriate penalty may be no penalty at all.⁹ If the Board’s decision is unfavorable, the employee can seek judicial review from the U.S. Court of Appeals for the Federal Circuit within 60 days.

Security Clearance Runs on a Separate Track

A positive drug test does not automatically revoke a security clearance, but the practical consequences can be as damaging as the disciplinary action itself. Agencies evaluating trustworthiness look at whether there was a pattern of use, how recent the use was, whether the employee’s statements have been consistent, and whether the employee minimized or shifted explanations over time. What you say during the disciplinary process often ends up in your security file, so careless statements early on can create problems that outlast any formal punishment.

For employees in sensitive positions, the combination of mandatory removal from sensitive duties under EO 12564 and a separate security review can end a career even if formal termination is avoided. The security adjudication process runs on its own timeline and criteria, independent of the discipline track.
