West Virginia drug testing laws for employers: pre-employment testing rules (2026)

West Virginia's Safer Workplace Act, W. Va. Code 21-3E, says "it is lawful for an employer to test employees or prospective employees for the presence of drugs or alcohol" as a condition of hiring, and protects employers that follow its safeguards from claims over acting on a result. As of October 2026, those safeguards include a written policy available to applicants, employer-paid testing, confirmation at a certified laboratory and a chance to report medications. Contractors on public improvement contracts over $100,000 must drug test every new employee under a separate act, W. Va. Code 21-1D. The Medical Cannabis Act bars refusing to hire someone solely because they are certified to use medical cannabis, and adult-use marijuana is not legal.

Does West Virginia have a drug testing law for private employers?

Yes. The Safer Workplace Act, enacted in 2017 by House Bill 2857, says in 21-3E-4 that testing is lawful, but that "in order to qualify for a bar from being subjected to legal claims for acting in good faith on the results of a drug or alcohol test, employers must adhere to the accuracy and fairness safeguards outlined in this article." Testing is not required (21-3E-14). The definitions in 21-3E-2 set the reach:

• Employer: any person, firm, company, corporation, labor organization, "employment agency" or joint labor-management committee with one or more full-time employees in the state. The United States, the state, its subdivisions, local governments and Native American tribes are excluded.
• Prospective employee: anyone who has applied, in writing or orally, to become an employee.
• Drugs: substances unlawful for nonprescribed use under the federal Controlled Substances Act.

Under 21-3E-3, the act does not apply to employers already covered by other West Virginia testing statutes, including coal mine operators under chapter 22A and public improvement contractors under article 21-1D, covered below.

What safeguards must a West Virginia pre-employment test follow?

1. A written policy applicants can see. Testing must be "carried out within the terms of a written policy which has been distributed to every employee subject to testing, and is available for review by prospective employees" (21-3E-8(a)). Testing need not be limited to signs of impairment.
2. Employer-paid testing. "An employer shall pay all actual costs for drug and/or alcohol testing required by the employer of employees and prospective employees" (21-3E-6(2)).
3. Proper collection. Under 21-3E-7, collection must be sanitary, any observer of a urine collection must be the same sex as the person tested, and samples must be labeled and handled under chain-of-custody and confidentiality procedures.
4. A chance to report medications. The person tested must be able to identify current or recent prescription and nonprescription drugs or other relevant medical information, which may be done through review of a positive by a qualified medical professional.
5. Confirmation at a qualified laboratory. Confirmatory drug testing must be done at a laboratory certified by SAMHSA, approved under the Clinical Laboratory Improvement Act, or approved by the College of American Pathologists, by a different chemical process from the screen, "a chromatographic technique such as gas chromatography/mass spectrometry, or another comparably reliable analytical method." An employer may take adverse action, "including job denial to a prospective employee, based only on a confirmed positive."
6. A split-sample retest on request. A person who challenges a result may have the split sample tested by another laboratory, at their own cost.

What can a West Virginia employer do after a positive or a refusal?

21-3E-9 lets an employer use a confirmed positive that violates its written policy, or a refusal by "an employee or prospective employee" to provide a sample, as the basis for actions including "refusal to hire a prospective employee." An employer that has a policy and testing program under the act faces no cause of action for actions based on a confirmed positive or a refusal (21-3E-11). Test communications are confidential and may not be used in evidence except in a proceeding about an action taken under the act (21-3E-15).

What does West Virginia's medical cannabis law mean for hiring?

The Medical Cannabis Act, chapter 16A, has an employment section, 16A-15-4(b):

• "No employer may discharge, threaten, refuse to hire or otherwise discriminate or retaliate against an employee ... solely on the basis of such employee's status as an individual who is certified to use medical cannabis."
• The act does not require "any accommodation of the use of medical cannabis on the property or premises of any place of employment," and does not limit discipline for being under the influence at work or working under the influence "when the employee's conduct falls below the standard of care normally accepted for that position."
• An employer is not required to commit any act that would put it in violation of federal law.

The protection is for status, and the statute does not say how a positive THC result fits. Rejecting a certified patient on a cannabis-only positive, with nothing else in the file, comes close to rejecting them for being a patient, so route positives through a medical review officer, ask about certification, and get advice before withdrawing an offer for a role that is not safety-sensitive or federally regulated. Outside the medical program, marijuana remains in Schedule I of West Virginia's controlled substances law (60A-2-204), and adult-use is not legal.

Do West Virginia public construction contractors have to drug test?

Yes. The Alcohol and Drug-Free Workplace Act for public improvements, article 21-1D, applies to construction on a public improvement let to contract for more than $100,000 (21-1D-2). A public authority may not award the contract unless the contractor and its subcontractors maintain a compliant written policy and give a sworn statement (21-1D-4), and bidders submit an affidavit. Under 21-1D-5, the policy must at least:

• require "preemployment drug tests of all employees," random testing of at least ten percent of employees who perform safety-sensitive duties each year, post-accident testing where there is reasonable cause, and reasonable-cause testing by trained supervisors;
• use a nine-panel urine screen that includes marijuana, an HHS-certified laboratory, confirmation of positives by gas chromatography or mass spectrometry, and medical review officer review of every positive;
• give a copy of the written policy "to each of its employees and to each applicant for employment";
• provide at least two hours of drug-free workplace education within six weeks of hire, and two hours of supervisor training a year.

A "preemployment drug test" is one "taken within the preceding twelve months from employment or seven days after hire" (21-1D-2(i)), and workers already required to follow DOT testing need no additional tests (21-1D-5a). Contractors report test counts, including pre-employment tests, to the public authority at least once a year (21-1D-7b).

How do West Virginia unemployment and workers' compensation treat drug tests?

• Unemployment. 21A-6-3(2) lists as gross misconduct, among other things, adulterating a sample to thwart a lawfully required test, refusing or failing random testing in safety-sensitive positions, and violating an employer's drug-free workplace program.
• Workers' compensation. Under 21-3E-16, an employee terminated for drugs or alcohol at a level the employer's policy prohibits forfeits indemnity benefits if injured while intoxicated, but only if the drug-free workplace program told all employees that working with drugs or alcohol in their body is prohibited and that refusing a post-injury test forfeits benefits.

Which federal rules still apply in West Virginia?

• DOT-regulated roles. Drivers and other covered transportation workers follow 49 CFR Part 40, with a verified negative pre-employment result before the first safety-sensitive function (49 CFR 382.301). The Safer Workplace Act says employers under a federal or state testing mandate must also meet that mandate's requirements.
• Rescheduling. The April 28, 2026 final order moved FDA-approved and state-medical-license marijuana to Schedule III, but DOT's Part 40 Q&A, updated May 15, 2026, says a state medical cannabis card still does not turn a marijuana positive into a negative.
• Federal contractors follow the FAR Drug-Free Workplace clause.
• The ADA: see pre-employment medical exams under the ADA before asking a candidate about prescriptions after a positive.

What should staffing agencies placing workers in West Virginia do?

• You are a covered employer. The Safer Workplace Act names "employment agency" in its definition of employer, so the agency's own policy, paid testing and confirmation steps carry the act's protection.
• Prepare for public improvement job orders. On a contract over $100,000, every worker you supply needs a pre-employment test taken within the prior twelve months or within seven days after hire, the contractor's written policy and the required education. Agree in writing who tests, who trains and who reports.
• Never charge the worker. Testing costs fall on the employer under 21-3E-6.
• Handle certified patients individually, separating safety-sensitive and DOT orders from others.
