8 Missouri Cannabis Laws You Must Know
Ever since dispensary licenses were awarded to Missouri applicants in January 2020, the competition has been intense. Out of the 1,200 applicants, only 192 dispensary licenses were awarded.
If you want to succeed as a dispensary owner in Missouri, the first step is understanding and adhering to the state’s extensive medical marijuana regulations.
In this post, we’ll simplify 8 Missouri cannabis laws you need to know to run a compliant dispensary.
Missouri Cannabis Laws At a Glance
Missouri has legalized medical marijuana only. Recreational use of cannabis is not legal.
Licensed dispensaries can sell mature plants, seedlings, concentrates, and edibles to licensed patients.
Medical cannabis is subject to a 4% tax in Missouri.
The regulatory body for Missouri’s medical marijuana industry is the Department of Health and Senior Services (DHSS).
Missouri residents over the age of 18 with a physician’s recommendation can apply for a medical marijuana patient license.
Medical marijuana patients can purchase a maximum of 4oz of flower or its equivalent per 30-day period.
Dispensaries must use state-approved seed-to-sale tracking software to manage inventory and report sales to Metrc.
All parts of the supply chain are licensed, including cultivators, testing labs, manufacturing facilities, transporters, and dispensaries.
Law #1: Managing inventory
Law: (G) All cultivation, infused products manufacturing, dispensary, testing, and transportation facilities shall implement inventory control systems and procedures as follows: 1. Each facility shall designate in writing a facility agent who is generally responsible for the inventory control systems and procedures for that facility; 2. All weighing and measuring of medical marijuana required by this rule must be conducted with a National Type Evaluation Program approved scale, which shall be capable of weighing and measuring accurately at all times and recalibrated at least yearly; 3. Each facility shall use a department-certified seed-to-sale tracking system to track medical marijuana from seed or immature plant stage until the medical marijuana is purchased by a qualifying patient or primary caregiver or destroyed. Records entered into the seed-to-sale tracking system must include each day’s beginning inventory, harvests, acquisitions, sales, disbursements, remediations, disposals, transfers, ending inventory, and any other data necessary for inventory control records in the statewide track and trace system;
5. Each dispensary facility shall be responsible for ensuring that every amount of medical marijuana sold or disbursed to a qualifying patient or primary caregiver is recorded in the seed-to-sale tracking system as a purchase by or on behalf of the applicable qualifying patient.
Explained: Here are the basics of compliantly managing inventory:
You must designate someone at your dispensary to oversee inventory.
Final oversight and auditing powers go to the Missouri DHSS.
Dispensaries must use a National Type Evaluation Program approved scale, to be calibrated at least annually.
Tracking of inventory, from seed to sale, must happen within a state-approved software. You must also make sure that every amount of medical marijuana disbursed (or sold) to licensed patients is recorded. See the list of approved seed-to-sale software vendors here.
Missouri uses Metrc as its track-and-trace system. Dispensaries are required to push every check in and transaction to Metrc in real time.
Law #2: Dispensary licensing
Law: (1) Access to Dispensary Facility Licenses. (A) The number of dispensary facility licenses will be limited to one hundred ninety-two (192) unless the department determines the limit must be increased in order to meet the demand for medical marijuana by qualifying patients. (B) Dispensary facility licenses will be limited to twenty-four (24) in each of the eight (8) United States congressional districts in the state of Missouri as drawn and in effect on December 6, 2018. (C) A facility license will be issued for a single facility in a single location.
4. If a facility is granted a license or certification but has not passed a commencement inspection within one (1) year of the department issuing the license or certification, the license or certification may be revoked.
(G) Cultivation, infused product manufacturing, and dispensary licenses and testing and transportation certifications are valid for three (3) years from the date the license or certification is issued and shall, except for good cause, be renewable by submitting, prior to expiration by at least one hundred fifty (150) days but no sooner than two hundred fifty (250) days, an updated application. (H) The department shall charge an application or renewal fee for a facility license or certification and also an annual fee once a license or certification is granted.
Explained: Any facility cultivating, manufacturing, selling, transporting, testing, or otherwise working with medical marijuana must be licensed.
An important note is that the regulations specify awarding only 192 dispensary licenses in Missouri. This means all the available licenses have been awarded.
Here’s the process of applying for a dispensary license in Missouri:
- A $6,000 non-refundable fee is required to apply for a dispensary license.
- Dispensaries must pay a $10,000 annual fee for their dispensary license. The Missouri DHSS is responsible for reviewing and approving dispensary licenses.
- “Any entity under substantially common control, ownership, or management” can be issued up to 5 dispensary licenses, 3 cultivation licenses, or 3 manufacturing licenses.
Basic commercial license applicant requirements:
- Proof of Missouri residency for at least 1 year.
- Entities must be majority-owned by natural persons who’ve been citizens of Missouri for at least 1 year and don’t claim residency in any other state or country.
- Facilities can’t be owned by or employ those with disqualifying felony offenses.
- All principal officers, owners, and managers must undergo a criminal background check by the Missouri State Highway Patrol within 6 months of applying.
Definition to know: “Majority owned” means more than 50% of the economic interests and more than 50% of the voting interests of an entity.
This law also outlines details of note for current license-holders:
- You must pass your commencement inspection within 1 year of being issued the license, or your license may be revoked.
- Your license is valid for 3 years from the date it was issued. You will need to renew by submitting an updated application between 150-250 days prior to expiration. Renewal fees will apply.
Note: Dispensaries and transportation facilities can’t be located within 1,000 feet of any elementary or secondary school, daycare, or church. The measurement is the shortest path between the two locations as lawfully traveled by foot.

Explained: First, you must use Metrc as the state track-and-trace system for Missouri. And second, the software you use to manage inventory in sales in your store — typically your POS — must be state-approved and integrate with Metrc.
License-holders can only use state-certified trace-and-trace software to manage inventory and report sales.
All sales must be reported to Metrc in real time, or immediately as the transaction occurs.
Failure to comply with seed-to-sale tracking requirements by any facility or employee can lead to the facility’s license being revoked.
