Mississippi Medical Cannabis Law

Reviewed October 23, 2026. This overview is general information, not individual legal or medical advice.

Eligibility and registration

Mississippi participation requires a qualifying condition, certification by a practitioner registered with the program, and a state-issued registry identification card. A diagnosis alone does not authorize use. See Miss. Code Ann. § 41-137-5 and the official patient guidance.

The state’s qualifying-conditions list includes specified diagnoses and qualifying symptoms of certain chronic, terminal or debilitating conditions. Legal eligibility does not establish that cannabis is effective or appropriate for every person with that condition. Discuss benefits, risks and alternatives with your treating clinician.

Legal limits are not medical doses

Under Miss. Code Ann. § 41-137-39, resident cardholders are limited to 24 MMCEUs in a rolling 30-day period and possession of 28 MMCEUs. Nonresident cardholders are limited to 6 MMCEUs per week, 12 MMCEUs in a consecutive 15-day period, and possession of 14 MMCEUs. Individual certification restrictions may be lower. These are legal ceilings, not recommended amounts to consume.

MMCEU means Mississippi Medical Cannabis Equivalency Unit. Conversion rules have changed. Consult the statutory definition in § 41-137-3 and the program’s current guidance; do not rely on an older conversion chart.

Cardholder protections have limits

Miss. Code Ann. § 41-137-15 prohibits denying custody, visitation or parenting time solely because a person is a cardholder. That is not immunity for unsafe conduct or a guarantee of any custody outcome. The section also protects schools, landlords and employers from state penalties merely for enrolling, leasing to or employing a cardholder; it does not create a general guarantee of employment or housing. The Act does not create an employee’s private action against an employer or alter existing employment relationships.

Firearms: state and federal law are separate

Section 41-137-15(3) provides state-law protections based on cardholder status. It does not itself determine federal firearms eligibility. 18 U.S.C. § 922(g)(3) addresses unlawful users of, or persons addicted to, controlled substances. Federal rules and court decisions affect its application. Do not treat a medical cannabis card or this webpage as assurance that firearm possession or a firearm purchase is lawful; obtain advice addressing your circumstances and current federal law.

Use restrictions

A patient card does not authorize use in a public place or motor vehicle. Do not drive while impaired. Review the Mississippi program FAQs for current restrictions and contact the program or your attorney about a specific legal question.
