Kansas Drug Testing Laws for Employers and Employees

Kansas drug testing laws give private employers wide latitude and give employees relatively few procedural protections. There is no general state statute telling private employers when or how to test, so in an at-will employment state, a company can require testing as a condition of hiring or continued employment and can fire a worker who refuses or fails, as long as the policy doesn’t run afoul of antidiscrimination law.¹ Where Kansas law does speak up is in three specific places that matter enormously to workers: workers’ compensation claims after an on-the-job injury, unemployment benefits after a firing, and testing rules for state government employees.

What Private Employers Can and Can’t Do

No Kansas statute prescribes procedures for private-sector drug testing. Employers can run pre-employment, random, post-accident, or reasonable-suspicion programs without meeting state requirements for advance notice, confirmatory testing, or medical review officer sign-off. The Kansas Department of Labor confirms that testing can be made a condition of employment.¹

The main limit comes from the Kansas Act Against Discrimination. Under K.S.A. 44-1009, an employer cannot use any employment procedure that results in discrimination based on race, religion, color, sex, disability, national origin, or ancestry without a valid business necessity.² A policy that screens only certain racial groups, targets workers with disabilities who take prescribed medications, or singles anyone out based on a protected characteristic can support a discrimination claim. The statute also bars retaliation against a worker who files a complaint or helps in a discrimination proceeding.

Two theories tend to fit drug testing disputes. Disparate treatment applies when the policy is enforced unevenly, for example when random selection appears to catch workers of a particular race or national origin more often. Adverse impact applies when a neutral policy produces skewed results, such as cutoff levels that disproportionately screen out workers with disabilities who take legitimate prescriptions. The KAAD specifically prohibits standards or methods of administration that have the effect of discriminating on the basis of disability.²

When Can an Employer Test You Before Hiring?

The Kansas Human Rights Commission draws a specific line on timing. Post-offer drug testing is permissible only when all entering employees in the same job category face the same requirement, and testing should not happen before a conditional offer of employment is extended.³ Screening applicants before an offer, or testing some candidates for a role while skipping others, invites a discrimination claim.

Kansas does not require private employers to disclose a testing requirement on job applications, though written policies and signed acknowledgments are common and help both sides if a result is later contested.

Workers’ Compensation and a Positive Drug Test

This is where the financial stakes are highest. Under K.S.A. 44-501, an employer is not liable for workers’ compensation if the employee’s injury was contributed to by drug or alcohol use, and the statute reaches street drugs, prescription medications, and over-the-counter drugs alike.⁴

A confirmatory test using gas chromatography-mass spectrometry or a comparably reliable technique creates a conclusive presumption of impairment at these levels:⁴

Marijuana metabolite: 15 ng/ml
Cocaine metabolite: 150 ng/ml
Morphine: 2,000 ng/ml
Codeine: 2,000 ng/ml
6-Acetylmorphine: 10 ng/ml
Phencyclidine: 25 ng/ml
Amphetamine: 500 ng/ml
Methamphetamine: 500 ng/ml (the specimen must also contain amphetamine at 200 ng/ml or above)

For alcohol, the threshold is a blood alcohol concentration of .04 or more at the time of injury. Once impairment is established at those levels, the law creates a rebuttable presumption that the impairment contributed to the injury, and the worker can only overcome it with clear and convincing evidence.⁴ That is a heavy burden.

Prescription and Over-the-Counter Medications

A positive result for a legitimately prescribed or over-the-counter drug doesn’t automatically forfeit benefits. The worker must show the medication was taken in therapeutic doses and that there were no prior incidents of on-the-job impairment from the same medication within the previous 24 months.⁴ Without that showing, benefits can be denied even for a lawful prescription.

Refusing a Post-Injury Test

Refusing a chemical test after a workplace injury forfeits workers’ compensation benefits when the employer had reasonable cause to suspect drug or alcohol use, or when the employer’s written policy clearly authorizes post-injury testing.⁴ It is one of the clearest and steepest consequences in Kansas law for a refusal.

How the Test Itself Can Be Challenged

A positive test doesn’t automatically end a claim. The statute imposes strict admissibility requirements. The sample must be collected within a reasonable time after the injury and supervised by a licensed healthcare professional. The lab must be approved by the U.S. Department of Health and Human Services or licensed by the Kansas Department of Health and Environment. The employer must prove the chain of custody beyond a reasonable doubt, and a split sample must be retained and made available to the employee within 48 hours of a positive result.⁴ A test that skipped any of those steps is vulnerable to being thrown out.

Unemployment Benefits After a Failed or Refused Test

Losing a job over a drug test in Kansas carries penalties well beyond the firing. Under K.S.A. 44-706, a positive chemical test is conclusive evidence of gross misconduct if the test was administered under one of these circumstances: it was required by law under the federal Drug Free Workplace Act, it was part of an employee assistance or treatment program, it was conducted under a written employer policy the employee knew about and that was a required condition of employment, or there was reasonable suspicion the employee was using or impaired by drugs while working.⁵

The gross misconduct label matters. A worker fired for ordinary misconduct is disqualified from benefits until they find new work and earn at least three times their weekly benefit amount. A worker fired for gross misconduct must earn at least eight times their weekly benefit amount to requalify, and all wage credits from the employer who fired them are canceled.⁵ That cancellation can shrink the total benefits available well after the disqualification period ends.

Refusing to submit to a drug or alcohol test is also conclusive evidence of gross misconduct under the same conditions, and so is tampering with or diluting a sample.⁵ Refusing or manipulating a test brings the same harsh unemployment consequence as failing one.

Marijuana Is Still a Regulated Substance in Kansas

Kansas has not legalized marijuana for recreational or medical use. Possession remains a criminal offense under K.S.A. 21-5706: a first offense is a Class B misdemeanor, a second is a Class A misdemeanor, and a third or subsequent offense is a drug severity level 5 felony.⁶

The one narrow exception involves cannabidiol treatment preparations. A person with a debilitating medical condition who possesses a CBD preparation and carries a physician’s letter can raise an affirmative defense to a possession charge.⁶ That defense is limited to criminal prosecution and gives no employment protection. An employer can screen for marijuana metabolites, treat a positive as a policy violation, and terminate without violating state law.

An out-of-state medical marijuana card has no legal weight in Kansas. And the workers’ compensation cutoff for the marijuana metabolite sits at just 15 ng/ml, which is low enough to catch use that occurred well before an injury.⁴

State Government Employees

State workers operate under a specific statute, K.S.A. 75-4362, that gives the director of the division of personnel services authority to run a drug screening program covering applicants for safety-sensitive positions and certain officeholders.⁷ Applicants for safety-sensitive roles cannot be tested until they receive a conditional offer, and the job posting must disclose the testing requirement.

Safety-sensitive positions include state law enforcement officers authorized to carry firearms, state corrections and parole officers, agency heads appointed by the governor and governor’s staff, employees with access to secure areas of correctional institutions, juvenile correctional facility employees, clinical and therapeutic staff at state mental health institutions, employees with access to secured biological labs in the Department of Health and Environment, and employees of the Kansas Office of Veterans Services. The statute also authorizes reasonable-suspicion testing of current safety-sensitive workers and of officeholders including the governor, lieutenant governor, attorney general, and state legislators.⁷

State employees get one protection private-sector workers do not. A first-time positive test generally cannot result in termination. The employee must be allowed to undergo a drug evaluation and complete any recommended education or treatment program. Only employees with access to secured biological laboratories at the Department of Health and Environment are exempt from that protection, and the statute does not stop an agency from imposing demotion or suspension in the meantime. Results are confidential and cannot be disclosed publicly except in civil service board hearings tied to disciplinary action.⁷

Federally Regulated Jobs Follow a Different Rulebook

State-level silence is beside the point in federally regulated industries. The Department of Transportation’s rule under 49 CFR Part 40 sets detailed procedures for workplace drug and alcohol testing across trucking, aviation, rail, transit, pipeline, and maritime workers in safety-sensitive roles.⁸ Part 40 covers specimen collection, laboratory analysis, medical review officer verification, and return-to-duty procedures, and it applies whether or not the employer has its own written policy.

Kansas employers who run commercial motor vehicles must comply with both DOT testing rules and Kansas employment law. The DOT rules require pre-employment, random, post-accident, and reasonable-suspicion testing of safety-sensitive employees.⁹ Employers who fail to comply with drug and alcohol testing record-keeping requirements face civil penalties for each violation under 49 U.S.C. 521(b), and criminal penalties are also available.¹⁰

Filing a Discrimination Complaint Over a Drug Test

An employee who believes a drug testing policy was applied in a discriminatory way can file a complaint with the Kansas Human Rights Commission. The deadline is six months from the last discriminatory act. If that window has closed but fewer than 300 days have elapsed, the KHRC will help forward the complaint to the federal Equal Employment Opportunity Commission.¹¹

Complaints can be started by phone, email, in writing, or in person at a KHRC office, and must be signed and verified before a notary public. Intake staff can be reached at 1-888-793-6874 or by email at KHRC.Intake@ks.gov.¹¹
