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

Mississippi regulates workplace drug testing through Title 71, Chapter 7 of the Mississippi Code, but private employers opt in: testing is voluntary, and the chapter applies only to an employer that elects it in its written policy and applicant notice. An employer that opts in must give applicants written notice before collection, use a qualifying laboratory, confirm every positive before refusing to hire, and pay for the tests it requires. A separate drug-free workplace act offers a 5% workers' compensation premium discount, and the state's medical cannabis law lets employers refuse to hire for medical cannabis use, as of October 2026.

Mississippi drug testing rules at a glance

Does Mississippi have a drug testing law for employers?

Yes, but it is opt-in for private employers. The chapter covers any employer with one or more employees in the state, or that has offered or may offer work to someone in the state (section 71-7-1(g)). Section 71-7-3(1) makes testing voluntary and says an employer that "elects voluntarily to follow this chapter" must follow all of its terms "without exception." Section 71-7-27 explains how a private employer elects: it puts a specific statement in its written policy and in its job applicant notice that the policy is implemented under the chapter. A private employer that does not elect, or rescinds its election, is "deemed to not be" testing under the chapter, and its rights and its applicants' rights are governed by contract and common law (section 71-7-27(2)).

Why opt in? An employer that complies gets real protection:

• Liability shield. A complying employer is "without liability from all civil actions arising from" testing performed in compliance, and a test result is presumed valid if the employer followed the chapter (section 71-7-25(3), (4)).
• For-cause decisions. Discipline or discharge on a positive confirmed test under the chapter is for cause, and a discharge is for willful misconduct (section 71-7-13(2), (3)).
• No disability label. A confirmed positive alone does not make someone a person with a "handicap" (section 71-7-13(1)).

To rescind, an employer posts a dated notice; for employees it takes effect no earlier than 10 working days later, but for job applicants it can take effect without notice (section 71-7-27(1)).

What are Mississippi's rules for pre-employment drug tests?

If you have elected the chapter, these steps apply to applicants:

1. Written policy. The policy statement must cover the grounds for testing and the actions on a positive, a statement that the chapter exists, confidentiality, how to report medications confidentially before testing, which positions are tested and on what basis, the consequences of refusing, rehabilitation options, the right to contest or explain a positive, a list of every drug tested by brand, common or chemical name, and any collective bargaining agreement. Post the notice and keep copies available for inspection (section 71-7-3(2), (3)).
2. Applicant notice. Tell the applicant in writing, "upon application and prior to the collection of the specimen," that they may be tested (section 71-7-3(5)). You may ask them to sign that they have read the policy; refusing to sign does not invalidate a test or stop you from refusing to hire (section 71-7-3(6)).
3. Collection. Collect under sanitary conditions with dignity preserved, label specimens, let the applicant list current or recent medications, and collect enough for at least two tests. A physician, nurse, qualified laboratory employee or person the State Board of Health deems qualified may collect (section 71-7-9(1) to (7)).
4. Laboratory. Confirmation tests are run only by a laboratory certified or accredited under the federal Clinical Laboratory Improvement Act, by SAMHSA or by the College of American Pathologists, or deemed so by the State Board of Health, using an alternate method of equal or greater sensitivity (sections 71-7-1(j), 71-7-11). The lab reports within 5 working days and names only the drugs you asked about (section 71-7-19).
5. Act only on a confirmed result. An employer "may not ... refuse to hire" on a positive that has not been verified by a confirmatory test (section 71-7-9(13)). With a refusal or a positive confirmed result, you may decline to hire (section 71-7-5(2)(a)).
6. Notice and explanation. The 5-working-day written notice of a positive, the right to a copy of the report, the 10-working-day window to explain, and the 90-day frozen sample for a self-paid retest are written for employees (section 71-7-9(9) to (12)). Extending the same steps to applicants costs little and supports the presumption that your result was valid.
7. Pay and keep it confidential. The employer pays for every test it requires of an employee or job applicant (section 71-7-9(16)). Results go only to the applicant and people with a need to know, unless the applicant consents in writing or another listed exception applies (section 71-7-15).

What is Mississippi's drug-free workplace discount?

The Drug-Free Workplace Workers' Compensation Premium Reduction Act, sections 71-3-201 to 71-3-225 (enacted as SB 2811 in 1997), gives an employer whose program substantially complies a 5% premium discount "if offered under the employer's workers' compensation insurance policy." The employer self-certifies to its insurer every year, and a misrepresentation means paying the discount back (section 71-3-207). A qualifying program needs five elements (section 71-3-209):

• a written substance abuse policy statement given to all employees (section 71-3-211);
• compliance with the Chapter 7 testing procedures, if the employer tests;
• an employee assistance program or a resource file of assistance providers (section 71-3-213);
• at least one hour of employee education before the program starts and every year (section 71-3-215); and
• at least two hours of supervisor training before the program starts and every year (section 71-3-217).

Separately, after a workplace injury the employer may test, and a positive test, including one for medical cannabis used under the Medical Cannabis Act, creates a presumption that the drug caused the injury (section 71-3-121). That rule governs comp claims, not hiring.

What does Mississippi say about marijuana and hiring?

• Medical cannabis. The Mississippi Medical Cannabis Act (SB 2095, 2022), administered by the Mississippi State Department of Health, is codified at sections 41-137-1 and following. Section 41-137-13 says the Act does not require any employer to permit or accommodate medical cannabis, does not prohibit refusing to hire "as a result, in whole or in part, of that individual's medical use of medical cannabis, regardless of the individual's impairment or lack of impairment," does not limit an employer's drug-testing policy, and does not affect the premium discount or the comp defenses above. Section 41-137-15(5) adds that the Act creates no private right of action by an employee against an employer.
• Adult-use. Mississippi's legal cannabis access is the medical program only; there is no adult-use program.
• Tobacco is different. Section 71-7-33 bars requiring applicants to abstain from tobacco during nonworking hours. There is no equivalent protection for cannabis.

So unlike Oklahoma, a Mississippi employer may treat a cardholder's THC-positive applicant test like any other confirmed positive under its policy.

Which federal rules still apply in Mississippi?

• The state chapter steps aside. Section 71-7-29 says the chapter "shall not apply to any employer who is subject to federal law or federal regulations governing the administering of drug and alcohol tests to any of its employees or applicants." A carrier with DOT-regulated drivers should therefore read this clause with counsel before relying on the chapter's protections for its other staff.
• DOT-regulated roles follow 49 CFR Part 40; a commercial driver needs a verified negative pre-employment result before the first safety-sensitive function (49 CFR 382.301).
• Rescheduling. The April 28, 2026 order moved FDA-approved and state-medical-license marijuana to Schedule III, and DOT's Part 40 guidance (May 15, 2026) says a Mississippi medical cannabis card still cannot make a DOT positive negative; 49 CFR 40.151(e) says the same for any physician recommendation.
• Federal contractors need the policy statement and awareness program in the FAR Drug-Free Workplace clause, which is separate from both state acts.
• The ADA: see pre-employment medical exams under the ADA.

What should staffing agencies placing workers in Mississippi do?

• Decide whether you elect the chapter. The election is made in your own policy and applicant notice. If your client has elected and you have not, the same worker may be tested under two different regimes.
• Put the applicant notice in your registration packet. Section 71-7-3(5) ties the notice to the application, which for an agency is registration, not the client interview.
• Match the discount to the policy. The premium act defines the employer as the entity subject to the state's workers' compensation law (section 71-3-205), so the discount follows whoever carries the comp policy for the placed worker.
• Watch federal clients. A client with DOT-regulated employees may fall under section 71-7-29.
• Licensing and onboarding: see Mississippi staffing agency licensing and hiring employees in Mississippi.

A checklist before you test a candidate in Mississippi

1. Decide whether to elect Title 71, Chapter 7, and if so, say so in the policy and applicant notice.
2. Write the policy with all ten section 71-7-3(2) items and post it.
3. Give the written applicant notice at application and before collection.
4. Use a qualifying lab, collect enough for two tests, and pay for the tests you require.
5. Never refuse to hire on an unconfirmed screen.
6. If you want the 5% discount, add the assistance resources, education and supervisor training, then certify to your insurer each year.

To draft the statement, start from the pre-employment drug testing policy template; for other states, see drug testing laws in hiring. Florida runs a similar voluntary program with a premium discount.
