Mississippi medical cannabis purchase limits are measured in Mississippi Medical Cannabis Equivalency Units, or MMCEUs. That adds complexity at checkout because flower, concentrates, and infused products each use a different conversion method.

Mississippi regulations define 1 MMCEU as 3.5 grams of medical cannabis flower, 1 gram of medical cannabis concentrate, or 100 milligrams of THC in an infused product. The biggest risk is assuming that every product should be converted based on package weight.
