Mississippi

Overview

Mississippi's Medical Cannabis Act took effect in 2022, after the state Supreme Court struck down a voter-approved initiative. The Mississippi Department of Health runs the patient program, and the Department of Revenue licenses dispensaries. Purchase limits are measured in Medical Cannabis Equivalency Units (MMCEUs). Smoking is allowed for patients on private property. Possessing small amounts without a card is a low-level offense, but adult-use cannabis is not legal.

Driving and Cannabis

Driving while impaired by cannabis is illegal in Mississippi, as it is in every state, whether or not the cannabis was obtained legally. Officers may rely on field sobriety tests, drug recognition evaluations, and blood tests, and some states set specific THC limits or zero-tolerance rules. Consuming cannabis in a vehicle and carrying open or unsealed packages where the driver can reach them are commonly prohibited. If you have used cannabis, the safest choice is not to drive.

Crossing State Lines and Federal Law

Taking marijuana across state lines is illegal under federal law, even between two states where cannabis is legal, and it may also violate the law of the state you enter. Marijuana is also prohibited on federal land, in national parks, and at airports under TSA jurisdiction. In 2026 the federal government moved FDA-approved products and state-licensed medical marijuana to Schedule III, but adult-use marijuana remains a Schedule I substance, and rescheduling does not legalize interstate transport. Separate federal changes to the legal definition of hemp take effect in late 2026 and will restrict many intoxicating hemp-derived THC products.
