Missouri has rapidly emerged as a leading cannabis market in the Midwest, establishing a robust framework for both medical and adult-use cannabis. Medical cannabis was first legalized in 2018, followed by adult-use legalization in November 2022, leading to a thriving industry across cities like St. Louis, Kansas City, Springfield, and Columbia.

Central to Missouri's commitment to a safe and regulated cannabis market are its rigorous testing requirements. Cannabis Testing Facilities in Missouri play a critical role, ensuring that all products, from flower to edibles, meet stringent safety and quality standards before reaching consumers. The state mandates comprehensive testing for contaminants such as pesticides, heavy metals, microbial impurities, and mycotoxins, as well as verification of cannabinoid and terpene content. Missouri regulators have also taken steps to establish a state-run reference testing lab, further enhancing oversight and promoting best practices for consumer safety and product integrity.
