Cannabis, Drug Testing, and DC Firings: A Wrongful Termination Attorney DC Guide to CEPAA

Cannabis is legal in DC for adults, and since July 2023, most DC employers can no longer fire workers just because a drug test came back positive for marijuana metabolites. The Cannabis Employment Protections Amendment Act (DC Law 24-190) rewrote the rules. A wrongful termination attorney DC employees consult after a failed test often finds that the firing was unlawful even when the company genuinely believed it was within its rights. The catch is that the safety-sensitive and federal-contract exceptions swallow more cases than employees expect, which makes the analysis fact-specific from the first phone call.

What CEPAA actually prohibits

CEPAA bars most DC employers from refusing to hire, firing, suspending, failing to promote, demoting, or otherwise penalizing an individual based on:

• Use of cannabis
• Status as a participant in DC’s medical cannabis program or another state’s program
• The presence of cannabinoid metabolites in a drug test, absent additional factors indicating impairment

The third point is where most cases get made. Cannabis metabolites linger in urine for days or weeks after use, so a positive test usually proves only that the person consumed at some point, not that she was impaired at work. CEPAA requires “additional factors” pointing to actual impairment before adverse action becomes lawful. A positive test combined with glassy eyes, slurred speech, an accident, or a documented incident might clear that bar. A positive test on its own does not.

Employers can still prohibit cannabis use, possession, and storage at the workplace or during work hours. The law protects off-duty use, not on-the-clock impairment.

The safety-sensitive carve-out

The biggest exception is the safety-sensitive position. CEPAA defines it as a job where it is reasonably foreseeable that an employee performing routine duties under the influence would likely cause actual, immediate, and serious bodily injury or loss of life to self or others.

The statute lists examples that qualify:

• Security services involving weapons (police, special police, security officers)
• Regular operation of a motor vehicle or heavy or dangerous equipment
• Regular work on an active construction site
• Regular work on or near power or gas utility lines
• Regular work with hazardous materials
• Supervision of people in custodial or institutional environments
• Administration of medication, performance of surgery, or other medical treatment requiring professional credentials

The designation has to be made and documented by the employer. A nurse pouring medications, a roofer working with active fall hazards, or a delivery driver running a box truck through Northwest can all be designated safety-sensitive. A graphic designer, an HR analyst, a paralegal, or an accountant generally cannot, even if the employer would prefer to designate everyone that way. Employer over-designation is a common pretext fight.

Federal contractor and federal employee exceptions

CEPAA does not override federal law. Two categories of workers usually fall outside its protection:

• Federal civilian employees, who remain subject to the Drug-Free Workplace Act and agency-specific rules
• Private-sector employees whose jobs are governed by Department of Transportation regulations (commercial drivers, pilots, transit, certain pipeline and maritime workers) or by a federal contract or grant that requires drug testing

The contractor exception is narrower than many employers claim. The federal contract or funding agreement must actually require the action, not merely encourage drug-free workplaces. A generic drug-free workplace policy adopted to mirror federal expectations is not enough. The Drug-Free Workplace Act itself does not mandate testing or termination for off-duty cannabis use.

How a Wrongful Termination Attorney DC workers trust builds a CEPAA case

When a positive cannabis test triggers a firing in the District, counsel typically looks at:

• Whether the position was formally designated safety-sensitive in writing before the test
• Whether the employer provided the annual CEPAA notice the law requires
• Whether the alleged “additional factors indicating impairment” were documented contemporaneously or invented after the fact
• The actual contract or funding agreement cited as a federal exception, to see whether it really requires the action
• Whether the worker is a medical cannabis patient, which triggers DCHRA disability-accommodation analysis
• The one-year filing window with the DC Office of Human Rights and the parallel private right of action

These cases frequently raise disability discrimination claims under the DCHRA when medical cannabis treats an underlying condition.

Medical cannabis patients get an extra layer

CEPAA amended the DCHRA so that an employer must treat a medical cannabis program patient’s use of medical cannabis to treat a disability the same as it treats the legal use of a controlled substance prescribed under medical supervision. That is essentially a reasonable-accommodation obligation grafted onto cannabis use. A patient with PTSD, chronic pain, or anxiety registered in DC’s or another state’s program cannot be fired for a positive test the way an unregistered recreational user might be, even outside the safety-sensitive context.

What to preserve if you have been fired

If a positive cannabis test or related accusation triggered your discipline or termination in DC:

• Save the test result, chain-of-custody form, and any related communications from the lab or employer
• Pull the job description and any written safety-sensitive designation, plus the CEPAA notice the employer was supposed to provide
• Write down the immediate context, including any accident, supervisor observations, accommodation conversations, or unusual behavior cited by the employer
• Keep your medical cannabis registration if you have one, and any documentation linking cannabis use to a disability

The DC Office of Human Rights publishes guidance and the CEPAA notice template at ohr.dc.gov. The Drug-Free Workplace Act’s actual text is on the Department of Labor’s website at dol.gov. Internal pages worth pairing with this post include a DC wrongful termination overview, a disability discrimination guide, and a severance review page.

Bottom line

A positive cannabis test in DC no longer means an automatic lawful firing. Off-duty use is protected for most workers, the safety-sensitive carve-out has real limits, and the federal contractor exception is narrower than employers often assume. A consultation with a wrongful termination attorney DC workers can rely on will sort the exceptions, evaluate the impairment evidence the employer claims to have, and identify whether DCHRA disability claims layer on top. If you have a severance offer in hand, get it reviewed before signing, since CEPAA waivers can be challenged when they are buried in a release that would otherwise foreclose a meritorious claim.
