The Statute — § 41-137-39
Mississippi caps medical cannabis purchases and possession under Miss. Code Ann. § 41-137-39, expressed in MMCEUs (Mississippi Medical Cannabis Equivalency Units). The cap structure differs for resident patients and non-resident reciprocity patients.
The Limits
| Limit | Mississippi Resident | Non-Resident |
|---|---|---|
| Per week | 6 MMCEUs | 6 MMCEUs |
| Per 30-day rolling period | 24 MMCEUs | 12 MMCEUs (per 15-day cycle) |
| Maximum simultaneous possession | 28 MMCEUs | 14 MMCEUs |
| Daily | Effectively 1 MMCEU | Same |
Source: Miss. Code Ann. § 41-137-39. Non-consumable products (topicals, lotions, soaps, suppositories) are not subject to possession caps.
What This Means in Real Product Terms
For a flower-dominant patient (most patients), 24 MMCEUs/month = 84 grams of flower per month, or about 3 ounces. That works out to roughly:
- About 168 0.5g pre-rolls per month (~5.6/day average).
- About 24 1/8-oz bags per month.
- About 12 1/4-oz bags per month.
For a concentrate- or edible-dominant patient (post 7/1/25, after SB 2748 recalibration), 24 MMCEUs/month equals 24 g of total THC across concentrates and infused products combined — a substantial allotment for even high-tolerance patients. See MMCEU explanation.
The Daily Pacing Effect
The 6 MMCEUs/week cap functions as an effective ~1 MMCEU/day average. A patient cannot buy a single 24-MMCEU month-supply in one transaction; they must spread purchases across at least 4 dispensary visits. This pacing requirement is designed to:
- Reduce potential for diversion (e.g., a single bulk purchase resold).
- Reduce patient stockpiling.
- Encourage ongoing relationship with a dispensary.
The Maximum Possession Limit
The 28 MMCEUs maximum simultaneous possession means a patient cannot lawfully possess more than the equivalent of 28 MMCEUs at any one time. In practical terms, a patient who buys their full 6 MMCEUs at the start of the week and has not yet used last week’s supply can be at or near the 28-MMCEU cap. Possession exceeding 28 MMCEUs technically falls outside the § 41-137 carve-out and could expose the patient to recreational possession penalties under § 41-29-139.
The 28-MMCEU cap is not a "rolling 30-day" or "annual" total; it is a snapshot maximum at any single moment. Properly managed, a patient can refill up to the cap each week without ever holding more than 28 MMCEUs at once.
Non-Consumable Products Are Exempt
Topicals, suppositories, soaps, and lotions are not subject to the 28-MMCEU possession cap. A patient may hold any quantity of CBD or THC topical lotion at home without it counting against the limit. The exemption is widely under-used by patients who could legitimately benefit from topical-only treatment for localized pain.
Non-Resident Limits
Non-resident reciprocity registrants face tighter limits:
- 6 MMCEUs/week (same as resident).
- 12 MMCEUs per 15-day period (vs. 24/30 days for residents).
- 14 MMCEUs maximum simultaneous possession (vs. 28 for residents).
These tighter limits reflect Mississippi’s preference for cautious reciprocity: non-residents may access medical cannabis during a Mississippi visit, but at half the resident allotment. See reciprocity page.
How Dispensaries Enforce the Cap at Point of Sale
All Mississippi dispensaries operate on the state’s seed-to-sale tracking system (METRC). At point of sale:
- The dispensary scans the patient’s MMCP card.
- The system reports the patient’s remaining weekly and 30-day MMCEU allotment.
- The system blocks any sale that would exceed the weekly cap, the 30-day rolling cap, or the 28-MMCEU possession cap.
Patients can verify their own remaining allotment through the MMCP portal at mmcp.ms.gov. Cap calculations roll forward day-by-day rather than resetting on calendar boundaries.
Cap Disputes and Adjustments
Patients who experience system errors (e.g., a sale was incorrectly recorded, or a dispensary refunded a purchase but the system did not reverse the MMCEU charge) can contact MSDH-MMCP for an adjustment. Adjustments typically take 5–10 business days. Frequent cap-related disputes are rare.
