Tennessee drug testing laws let employers screen job applicants and employees, but employers who opt into the state’s voluntary Drug-Free Workplace Program have to follow set rules: written notice of the policy, testing by a certified lab, confidential handling of results, and a five-working-day window for you to explain or contest a positive result to a medical review officer.1Justia. Tenn. Code Ann. § 50-9-105 Federal rules add stricter requirements for safety-sensitive transportation jobs.2U.S. Department of Transportation. 49 CFR § 40.1
When an Employer Can Test You
Tennessee’s Drug-Free Workplace Program is voluntary. Employers who join it get a workers’ compensation premium credit and a legal presumption that a positive test caused a workplace injury, but in exchange they have to follow the program’s procedural rules.3Justia. Tenn. Code Ann. § 50-9-1034Justia. Tenn. Code Ann. § 50-6-110 If your employer participates, the protections described below apply to you.
A separate set of federal rules from the U.S. Department of Transportation governs testing for safety-sensitive transportation roles, and those rules apply regardless of whether the employer joined the state program.2U.S. Department of Transportation. 49 CFR § 40.1 Employers outside both frameworks may still test, but the specific procedural rights below come from the state program.
What Your Employer Must Tell You Before Testing
Under the state program, employers must give every employee and applicant a written policy before any testing starts. That policy has to spell out:1Justia. Tenn. Code Ann. § 50-9-105
- The types of drug or alcohol testing that will be required
- The actions the employer may take on a positive result
- The specific drug classes being screened
- A confidentiality statement
- Your right to contest or explain a positive result to a medical review officer within five working days
When an employer first rolls out the program, at least 60 days must pass between the initial notice and the effective date.1Justia. Tenn. Code Ann. § 50-9-105 Job vacancy announcements have to mention testing, and the policy must be posted somewhere visible on the premises.5Justia. Tenn. Code Ann. § 50-9-106
The lab running the analysis has to be certified by the U.S. Department of Health and Human Services or the College of American Pathologists, or licensed by the Tennessee Department of Health.6Justia. Tenn. Code Ann. § 50-9-110
The Situations You Can Be Tested In
Pre-Employment
A covered employer can test you after making a conditional offer of employment. A confirmed positive or a refusal to test is grounds to withdraw the offer.5Justia. Tenn. Code Ann. § 50-9-106 Applicants get the same five-working-day right to challenge a positive result with a medical review officer that employees do.1Justia. Tenn. Code Ann. § 50-9-105
Post-Incident
Employers in the state program are required to test after a workplace accident that results in an injury as defined by workers’ compensation law.5Justia. Tenn. Code Ann. § 50-9-106 For commercial drivers, federal rules are tighter: alcohol tests within eight hours and controlled substance tests within 32 hours of qualifying accidents.7Cornell Law School. 49 CFR § 382.303
Reasonable Suspicion
An employer can require a test when there’s reason to believe you’re using drugs or alcohol in violation of company policy. That belief must rest on specific, objective facts and reasonable inferences drawn from them, such as observed physical symptoms or erratic on-the-job behavior.3Justia. Tenn. Code Ann. § 50-9-103 A hunch is not enough.
Random
Random testing isn’t required to participate in the state program. It is, however, standard under federal rules for regulated drivers, where selection must use a scientifically valid method that gives every driver an equal chance, and a selected driver generally has to report to the testing site immediately.8Cornell Law School. 49 CFR § 382.305
Your Right to Challenge a Positive Result
If you test positive, you have five working days from the written notification to explain or contest the result with a medical review officer.1Justia. Tenn. Code Ann. § 50-9-105 This is where a legitimate prescription or other medical explanation gets considered before your employer acts on the result. The MRO verifies the result before any final employment decision.
Confidentiality of Your Results
Your test results and related records are confidential. They can’t be used in criminal proceedings against you, and they’re generally shielded from public disclosure. The law does carve out exceptions: management can use the records for disciplinary decisions, legal counsel can use them defending a civil or administrative claim tied to the test, and disclosure is permitted for certain legal proceedings and professional licensing reviews.9Justia. Tenn. Code Ann. § 50-9-109
What Happens if You Refuse
If you refuse a required test, your employer can discipline you, including termination. Refusal after a workplace injury also triggers a legal presumption that drugs or alcohol caused the injury, which can cost you workers’ compensation benefits unless you rebut it with clear and convincing evidence.10Cornell Law School. Tenn. Comp. R. & Regs. 0800-02-12-.064Justia. Tenn. Code Ann. § 50-6-110
The same presumption applies to a confirmed positive test, so if you believe the result is wrong or your medication explains it, using the five-day MRO window is the point at which that gets on the record.
