Tennessee does not force any private employer to drug test. Instead, the state built an incentive program: employers who set up a certified Drug-Free Workplace Program under the Tennessee Bureau of Workers' Compensation get real legal and financial advantages in exchange for following a specific set of rules. Those rules are spelled out in the Tennessee Drug-Free Workplace Program, administered by the Department of Labor and Workforce Development, and in the program's implementing rule, Chapter 0800-02-12 of the Rules of the Tennessee Department of Labor and Workforce Development, Bureau of Workers' Compensation. This guide walks through what certification requires, what it buys an employer, and where the rules leave room for the employer's own policy choices.
What the Drug-Free Workplace Program Is
The program is voluntary. An employer covered by the Tennessee Workers' Compensation Act can apply to the Bureau of Workers' Compensation, adopt a written policy that meets the rule's requirements, train employees and supervisors, and test according to the rule. Once certified, the employer is a "covered employer" under the rule, and it keeps that status for twelve months at a time, renewed annually. The rule's stated purpose is to deter drug and alcohol use in the workplace and to reduce the risk of injury and property damage that substance use can cause on the job, and its authority traces back to Tennessee Code Annotated Title 50, Chapter 9, along with the workers' compensation premium and burden of proof statutes in Chapter 6.
Employers that do not certify are not barred from testing. They can still test job applicants and employees under their own policy, subject to general employment law, but they do not get the specific benefits the certified program provides, and a positive test outside the certified program does not carry the same workers' compensation presumption described below.
Why Employers Certify: The Benefits
The rule lists three benefits tied to certification, all of which begin accruing on the date the Bureau of Workers' Compensation receives a completed application:
- A premium discount on the employer's workers' compensation insurance policy, authorized under Tennessee Code Annotated Section 50-6-418. The discount accrues on a pro rata basis from certification and must be applied by the workers' comp carrier, or refunded after the annual audit. Because the amount and mechanics run through the carrier's rate filing, an employer should confirm the current discount with its own carrier and with the Bureau rather than assume a fixed number, since workers comp drug testing premium programs vary by state and by policy.
- A shift in the burden of proof in a workers' compensation claim under Tennessee Code Annotated Section 50-6-110(c), described in more detail below.
- Legal cover for personnel decisions. A covered employer that discharges or disciplines an employee, or refuses to hire a job applicant, in compliance with the rule and with Tennessee Code Annotated Section 50-9-108, is treated as having acted for cause.
To keep any of these benefits, the employer has to renew its application every year and keep following the rule. Testing for substances beyond the list posted on the Bureau's website is allowed, but the certified program's benefits do not extend to results from that extra testing.
Written Policy and the 60 Day Notice
Before an employer can rely on the program, it has to put its policy in writing and give employees real notice. Under the rule, a covered employer must provide at least sixty days' prior notice to all employees before a drug-free workplace program takes effect, stating the effective date. The written policy also has to be posted somewhere conspicuous on the premises, and copies have to be available for employees or applicants to review during business hours, typically through human resources. Any job posting for a position that requires drug or alcohol testing has to disclose that fact in the vacancy announcement.
The rule also requires training, not just a policy handout. Employees must receive at least one hour of training within sixty calendar days of the program's start, or within sixty calendar days of hire for anyone hired afterward, covering the employer's policy, testing procedures, consequences for violations, the specific drugs tested, and any employee assistance program available. Supervisors need an additional two hours covering how to recognize and document possible substance abuse and how to explain the program to employees.
Types of Testing
The rule sets out five categories of testing a covered employer conducts, each with its own conditions. The table below summarizes them as described in the rule.
| Testing type | When it applies | Key condition |
|---|---|---|
| Pre-employment | After a conditional offer of employment | A positive point of collection screen must be confirmed by a certified laboratory before it is used to deny hire; testing applicants who tested negative in the prior twelve months is optional |
| Reasonable suspicion | Based on specific, articulable facts such as observed impairment, a credible report, or an accident causing injury or over five thousand dollars in property damage | The employer must document the basis in writing within twenty four hours and give the employee a copy |
| Routine fitness for duty | As required by employer policy or applicable law | Must be applied consistently under the written policy |
| Follow-up | After a positive test, at least once a year for two years | No advance notice of the testing date may be given to the employee |
| Post-accident | After an accident that results in an injury to an employee | Emergency medical care is never delayed for specimen collection; the injured employee submits to testing when the injury is reported |
A refusal to submit to a required test can be treated the same as a positive result. If an injured worker refuses a post-accident test, the rule presumes, absent clear and convincing evidence otherwise, that drug or alcohol use was the proximate cause of the injury.
Lab, Confirmation, and MRO Requirements
The program borrows heavily from the federal Department of Transportation testing model. Initial screening can be done at the point of collection with a device the Bureau has approved, but any presumptively positive result has to be confirmed at a certified laboratory, meaning one that meets United States Department of Health and Human Services or Substance Abuse and Mental Health Services Administration standards, or College of American Pathologists Forensic Urine Drug Testing accreditation. Confirmation uses a method that is scientifically different from the initial screen, and cutoff levels for both the initial and confirmation tests are tied to Substance Abuse and Mental Health Services Administration guidance, detailed further on the same Bureau of Workers' Compensation drug testing page. Reported cutoff pairs on that page include, among others, marijuana metabolite at 50 nanograms per milliliter on the initial screen and 15 on confirmation, cocaine metabolite at 150 initial and 100 confirmation, and opiates at 2000 nanograms per milliliter on both stages, alongside a 0.04 alcohol concentration threshold for employees in safety sensitive positions.
A confirmed positive result has to go through a Medical Review Officer before it can be used against an employee or applicant. The Medical Review Officer is a licensed physician with training in substance abuse disorders, laboratory procedures, and chain of custody, who reviews the confirmed result against any legitimate medical explanation, such as a current prescription, before verifying it as positive. Per the Bureau's own Drug-Free Workplace Program FAQ page, the Medical Review Officer may only consider a prescription issued within the six months prior to the positive confirmed result when deciding whether it explains the finding. An employer cannot discipline, refuse to hire, or require rehabilitation of someone based only on an unconfirmed or unreviewed positive screen. For a closer look at how that review works in practice, see the Medical Review Officer process explained for employers.
The Workers' Compensation Presumption
This is the part of the program that most changes the stakes of a positive test. Under Tennessee Code Annotated Section 50-6-110(c), referenced directly in the rule's authority citations, an employee or job applicant with a confirmed positive post-accident test for a substance on the Bureau's list may lose entitlement to workers' compensation benefits for that injury, provided the test was conducted according to the rule. The rule creates a rebuttable presumption that the drug or alcohol was the proximate cause of the injury once that confirmed positive result exists. The employee can attempt to rebut that presumption, but the burden has shifted onto them rather than sitting with the employer, which is the burden of proof shift the statute and rule both describe as a program benefit.
Employee Protections and Confidentiality
The program is not one directional. A covered employer cannot discipline an employee solely because the employee made a first voluntary request for treatment for a drug or alcohol use disorder, as long as the employee has not already tested positive and is not currently facing a reasonable suspicion or post-accident test. Test results themselves are treated as confidential. The rule allows information to move between the employer, the laboratory, the Medical Review Officer, an employee assistance program, and legal counsel handling a workers' compensation claim, but otherwise keeps results out of general circulation. None of this displaces a covered employer's obligations under federal law; the rule specifically states it does not authorize testing in any manner inconsistent with the Americans with Disabilities Act or the National Labor Relations Act, so employers should treat medical and disability related questions raised by a test result as a separate legal question from the testing procedure itself.
Where Marijuana Fits
Tennessee has not enacted a broad medical or recreational marijuana legalization law that changes workplace drug testing. The Drug-Free Workplace Program rule does not carve out an exception for marijuana, and the substance stays on the standard testing panel referenced on the Bureau's website. Employers relying on the certified program can continue to test for marijuana and act on a confirmed positive result the same way they act on other confirmed positives, subject to the same Medical Review Officer review and confirmation requirements described above. Because state approaches to marijuana and drug testing keep shifting elsewhere in the country, employers with multi-state operations should confirm current status for each state where they operate rather than assume Tennessee's approach applies uniformly.
Frequently asked questions
Is drug testing mandatory for Tennessee employers?
No. Tennessee's Drug-Free Workplace Program is voluntary. An employer chooses to certify with the Bureau of Workers' Compensation in order to receive the program's benefits, and employers that do not certify may still test under their own policy, subject to general employment law.
How much notice must an employer give before starting a testing program?
The rule requires at least sixty days' prior written notice to employees before a drug-free workplace program takes effect, along with a posted policy and copies available for review.
What happens if an employee tests positive after a workplace accident?
A confirmed positive post-accident test for a substance on the Bureau's list can create a rebuttable presumption that the drug or alcohol was the proximate cause of the injury, which may affect the employee's entitlement to workers' compensation benefits under Tennessee Code Annotated Section 50-6-110(c). Emergency medical care is never delayed to collect a specimen.
Can an employer act on a positive test before a Medical Review Officer reviews it?
No. A covered employer cannot discharge, discipline, refuse to hire, or require rehabilitation of an employee or applicant based solely on a positive result that has not been confirmed by a laboratory and verified by a Medical Review Officer.
Does Tennessee require employers to accommodate marijuana use?
Tennessee has not enacted a marijuana legalization law that requires workplace accommodation, and the Drug-Free Workplace Program rule does not exempt marijuana from testing. Employers should still apply the same confirmation and Medical Review Officer review process to any positive result.
What benefit does certification give an employer in a workers' compensation claim?
Certification shifts the burden of proof under Tennessee Code Annotated Section 50-6-110(c) and gives the employer a premium discount on workers' compensation insurance under Section 50-6-418, along with for cause protection for personnel decisions made in compliance with the rule.
American Screening Corporation supplies point of collection drug test cups, dip cards, and oral fluid devices that Tennessee employers can use as part of a certified Drug-Free Workplace Program testing lineup, alongside lab confirmation and Medical Review Officer services for any presumptive positive. Employers building or renewing a program can review the current lineup of drug test cups to match their panel to the substances listed on the Bureau's website.
