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: How do I get training or a demo of Metrc?
A: Metrc will be publishing information and a schedule of events in the coming weeks. Please check back on the Metrc page periodically for updates. In the mean time you can look at the Metrc videos on our YouTube channel for more information.
Q: What POS systems will be available with Metrc?
A: Metrc will provide a list of validated 3rd party integrators, similar to what we have done for other states. You can look at other Metrc state customers for samples of what this list will look like. These lists are available on metrc.com under the customer tab.
Q: Will I have to use Metrc and a POS system?
A: A licensee can input sales data directly into Metrc through the user interface, but most licensees prefer to use 3rd party POS providers using the Metrc API (Application Programming Interface) or CSV (Comma-Separated Values) upload functions. Once we have worked out the details with the state, more information will be available.
Q: Will there be an API integration with Metrc?
A: Yes, Metrc will be releasing our API once we have worked out the details with the state. More information will be available in the coming weeks.
Q: How does the system work?
A: Metrc is a hosted, real-time system that uses serialized tags with bar-code, human-readable and Radio Frequency Identification (RFID) tags attached to every plant, and labels attached to wholesale packages to track marijuana inventory. Each tag is attached to a plant to facilitate tracking through different stages of growth, as well the drying and curing processes, to the sale of the product.
Q: Do I need to purchase any additional hardware such as computers, bar-code readers or RFID readers.
A: Metrc is a completely web-hosted system. That means that all access to Metrc is done via the internet and only requires an internet connection and a web browser. No additional hardware is required. Also, there is no software to download, install, or maintain.
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: What if I have technical issues after the system has deployed?
A: Metrc has a dedicated team of support staff who will be available to resolve any technical support issues. The support desk can be contacted via phone or email, at 877-566-6506 and
Q: Are RFID readers required?
A: Activities in Metrc can be accomplished without Bar-code scanners or RFID readers. Although the use of these tools may increase productivity and efficiencies, it will be up to each licensee to decide to use Bar-code or RFID readers, but their use is not required.
