Mississippi Drug Testing Laws for Employers

An Election Made in the Wording

Miss. Code Ann. 71-7-1 through 71-7-33 sets out a complete testing scheme, and 71-7-3(1) states the bargain plainly: the election is voluntary, but an employer that elects must follow all the terms of the chapter without exception.

The election is made by including, in the written policy statement and in the job applicant notification, a specific statement that the policy is implemented pursuant to the chapter. That is worth pausing on, because it means a Mississippi program can be opted into by a drafting decision someone made years ago, and an employer may not know which side of the line it is on until it looks at its own policy text.

Rescission works the same way: post a written and dated notice on the premises, effective as to employees no earlier than ten working days later, and effective as to applicants immediately.

The Federal Carve-Out, and the Word "Any"

Section 71-7-29 removes from the chapter any employer subject to federal law or regulations governing the administering of drug and alcohol tests to any of its employees or applicants.

For a mixed workforce that is a significant sentence. An employer with a handful of DOT-regulated drivers alongside a large non-regulated population may sit outside the chapter entirely on the strength of those drivers. That is worth establishing deliberately rather than discovering during a dispute, because it determines whether the rest of this page applies to you at all.

Three Things That Break a National Program

If you do elect in, these usually require changes:

1. Specimen types are restricted. The Department of Health regulations allow urine for drugs, and breath or saliva followed by blood for alcohol. A hair panel or an oral fluid drug panel does not fit.
2. A medical review officer is mandatory and exclusive. The MRO is the only person permitted to review results, and the laboratory may send results only to the MRO. A workflow where results land with HR first does not comply.
3. The calendar is fixed. Thirty days of policy lead time before the program starts; the laboratory report within five working days of the test; employer written notice to the employee within five working days of receiving a positive confirmed report; ten working days for the employee to explain; and ninety days of frozen retention during which the employee may buy a retest at a laboratory of their own choosing.

The Policy Contents, Including Mandatory Wording

Section 71-7-3(2) requires the written policy statement, provided at least thirty days before implementation, to contain ten items: a general policy statement identifying the grounds for testing and the actions the employer may take on a positive confirmed result or other violation; a statement advising of the chapter's existence; a confidentiality statement; procedures for confidentially reporting prescription and nonprescription medication use before testing; the circumstances under which testing may occur and which positions are subject to reasonable suspicion, neutral selection or other testing; the consequences of refusing; information on assessment and rehabilitation where discipline is not deemed necessary; a statement that an employee receiving a positive confirmed result may contest or explain it; a list of all drugs tested for, by brand, common or chemical name; and a statement on any applicable collective bargaining agreement or contract.

Beyond that list, Department of Health Rule 53.9.1 prescribes mandatory verbatim language every electing employer must include, covering advice of the Act's existence, a full confidentiality paragraph, and a requirement that the person be given a medication disclosure form for prescription and nonprescription medications taken within 45 days before testing — submitted directly to the MRO so that nobody other than the MRO has access to it.

The applicant track has no waiting period: notify the applicant in writing, upon application and before specimen collection, that they may be tested. The employer may ask for an acknowledgment, and a refusal to sign does not invalidate results, bar the test, bar action consistent with the policy, or bar a refusal to hire.

Random Testing, Called Neutral Selection

Electing employers may require all employees to submit to neutral selection testing as a condition of employment or continued employment. Mississippi does not prescribe the pool shape, the selection algorithm, an independent administrator or an audit trail — a marked contrast with Iowa. The statute requires only that selection be neutral, and that the written policy describe which positions are subject to which kind of testing.

The chapter also allows routinely scheduled fitness-for-duty examinations that are part of established policy or scheduled for all members of a classification or group, and follow-up testing where an employee enters rehabilitation or previously tested positive within a twelve-month period. Government employers face a much narrower regime tied to law enforcement, security, firearms, sensitive information and public health or safety roles.

Post-Injury Testing Applies Either Way

This is the part that does not depend on your election. Miss. Code Ann. 71-3-121(1) gives every Mississippi employer the right to administer testing, or require an employee to submit to it, when the employee sustains or asserts a work-related injury.

A positive indicating the presence at the time of injury of an illegally used drug, a valid prescription medication taken contrary to instructions or label warnings, medical cannabis used in accordance with the Mississippi Medical Cannabis Act, or .08 percent or more alcohol by weight volume, creates a presumption that the proximate cause of the injury was that use. A refusal to submit immediately after the alleged injury creates the same presumption. The burden then shifts to the employee to prove the use or intoxication was not a contributing cause. Results are admissible solely on causation, and no defamation or reputation claim arises against the employer under the section.

Note that medical cannabis was written into that presumption by the Medical Cannabis Act itself in 2022. Guidance predating that will miss it.

Cannabis: The Bluntest Language in the Country

Mississippi has medical cannabis and no adult-use program, and its medical statute contains no employment protection of any kind. It provides that the chapter shall not be construed to require an employer to permit, accommodate or allow medical use or to modify any job or working conditions; to prohibit an employer from refusing to hire, discharging, disciplining or taking adverse action as a result, in whole or in part, of an individual's medical use, regardless of the individual's impairment or lack of impairment; to prohibit or limit a drug-testing policy; to interfere with federal requirements including 49 C.F.R.; or to establish any right to sue an employer over such an action.

That "regardless of impairment" clause is about as direct as this gets. Alabama's medical cannabis statute uses the same formulation; between them they are the clearest employer-side language on the subject in any state we have covered.

The Premium Discount, and What We Could Not Verify

Mississippi has a separate Drug-Free Workplace Workers' Compensation Premium Reduction Act at Miss. Code Ann. 71-3-201 et seq. Its existence, and its character as a premium discount for employers establishing a conforming drug-free workplace program, is confirmed by the Medical Cannabis Act's own cross-reference to it.

We are not going to tell you the percentage. Mississippi does not publish its code free of charge on an official state site, and we could not verify the discount figure, the certification mechanics or the program's preconditions from a primary official source. A number is widely quoted elsewhere; we have no way to confirm it, so we are leaving it out rather than repeating it. If the discount is part of your business case, confirm it against the current text of 71-3-201 through 71-3-225 before relying on it.

For the same reason, the statutory text on this page comes from the Legislature's own 2026 bring-forward bill, which reprints sections 71-7-1 through 71-7-33 verbatim as existing law. We cite it as the Legislature's official reprint of current code text, not as enacted legislation — the bill itself was introduced only.

What Election Buys

The payoff for following every term is substantial: freedom from civil actions arising from the program, a rebuttable presumption that results are valid, discharge for cause, and a statutory willful-misconduct characterization. For an employer with a large Mississippi workforce and real claims exposure, that package is usually worth the rigidity. For an employer whose panel depends on hair or oral fluid, or whose results workflow cannot be rebuilt around an exclusive MRO, staying outside the chapter and running on contract and common law is a legitimate answer rather than a failure.

Mississippi's employment base spans automotive and advanced manufacturing, shipbuilding and aerospace, poultry and catfish processing, forestry and wood products, transportation and warehousing, energy and petroleum refining, healthcare, and gaming and hospitality. Shipbuilding and poultry processing in particular carry the injury profile that makes the 71-3-121 presumption valuable regardless of which side of the election you land on.
