On behalf of Missouri’s Medical Marijuana Regulatory Program (MMRP), we welcome you to the to the Missouri Marijuana Enforcement Tracking Reporting & Compliance (METRC) webpage. Missouri’s Medical Marijuana Regulatory Program (MMRP) is working with METRC to implement the seed-to-sale track and trace requirements of Article XIV of the Missouri Constitution, and we are happy to offer this site as a resource for Missouri’s medical marijuana facilities.
While the MMRP is responsible for general regulation of facilities, including overseeing compliance with regulations related to the statewide track and trace system, METRC is responsible for implementation of the technical and operational components of the tracking system. They will provide medical marijuana facilities with training sessions, webinars, and instructions in order to facilitate a thorough understanding of the track and trace system.
We encourage our licensed and certified facilities to view METRC as a partner in their success, and we look forward to working with both METRC and our facilities to provide Missouri’s qualifying patients with safe and secure access to medical marijuana.

Q: What’s the status of Metrc in Missouri?
A: Metrc continues to partner with the Missouri Department of Health and Senior Services to implement our system and support the launch of the medical marijuana market. We have continued to deliver key project milestones - including system access, training classes, a beginning inventory guide for industry, a lab testing guide, and a Missouri-specific supplemental guide. Metrc has also overseen the development and implementation of a patient registry, a facility licensing program, and an employee licensing program, in partnership with our subcontractor.
We are looking forward to the first licensees using our system over the next few weeks and helping ensure a safe and secure medical marijuana market in Missouri.
Q: How do I start using Metrc?
A: First, licensees must request a commencement inspection from the state. Once that is scheduled, licensees should sign up for an introductory training class. Once this is complete, licensees should request to be credentialed into the system, to set up their account and access our software. Once trained and credentialed, licensees can begin using the system and ordering tags.
Q: How do I schedule training?
A: Once licensees start the commencement process with the state, they can sign up for trainings using the “Schedule Training Now” button at the top of this page. Additional trainings will be scheduled and announced in partnership with the Department of Health and Senior Services.
Q: What do I need in order to use Metrc?
A: Metrc’s track-and-trace system relies on two main components: software and RFID tags. Licensees use our tags to physically track cannabis products and use our software to enter any information related to those products.
Metrc tags are produced through our patented process, designed to meet the unique environmental conditions for marijuana cultivation, manufacturing, and retail. Since licensees aren’t responsible for printing their own tags, they can focus on their core business and avoid large costs, such as printing equipment, supplies, and labor to assemble, test, and input tracking tags. This is all handled by Metrc to keep the costs to licensees affordable and proportional to the size of their business. As in our other jurisdictions, tags cost $0.25 per package tag and $0.45 per plant tag.
Our cloud-based software requires internet connection and computer to access and use it. There is no additional hardware required or new software to download, install or maintain.
Q: How does the system work?
A: Metrc is an integrated system that allows for real-time tracking and tracing of marijuana plants and products. Licensees attach unique, serialized tags to every plant or wholesale package. These tags feature readable text, barcodes, and RFID chips to uniquely identify for each plant and package physically and in the online platform. Users then enter information related to those plants and packages, including weight, transfer of custody, and test results in our online software platform. That information is available to the licensee and the Missouri Department of Health and Senior Services.
Q: Will other licensees be able to see my inventory information?
A: No. Licensees will only be able to access their own information through Metrc. They will not be able see any information about any other licensee.
Q: Are RFID readers required?
A: No. Our use of RFID tags enables both regulators and licensees to more efficiently track inventory with RFID readers, but their use is not required.
Q: Will there be Application Programming Interface (API) integration with Metrc?
A: Yes, our system features an open API, allowing for easy integration with a variety of third-party services. MMetrc requires third-party integrators to demonstrate basic knowledge of our system before being allowed to integrate into our system. We will release our API once we have worked out the details with the state. More information will be available in the coming weeks.
Q: What point-of-sale (POS) services will be available with Metrc?
A: Our system features an open API, allowing for easy integration with a variety of third-party integrators including POS. We will publish a list of validated third-party integrators on this page after our API agreement is finalized with the state.
Q: Will I have to use a POS system?
A: No. A licensee can input sales data directly into Metrc through the user interface or Comma-Separated Values (CSV) file upload, but many licensees prefer to use third-party POS providers using the Metrc API.
Q: What if I have technical issues when working to get credentialed into the Metrc system or once my tracking is up and running?
A: Metrc has a dedicated team of support staff available to resolve any technical support issues. The support desk can be contacted via phone or email, at 877-566-6506 and
