The Missouri Department of Health and Senior Services (DHSS) has awarded six seed-to-sale tracking companies licenses to operate in the state’s forthcoming medical cannabis market.

The licensees are MJ Freeway, Bio-Tech Medical Software, Swin, Artemis Agtech, Validated Housing and Retail Innovation, according to The Motley Fool.

Two companies, Leaf Logix Technologies and Canna Botanicals, were denied licenses, the news outlet reported.

The licensees will use their technology platforms to track medical cannabis from the seed or immature plant stage through the product’s sale at a dispensary.

Missouri legalized medical cannabis in 2018 and has worked quickly to license the nascent industry. DHSS issued testing lab and cultivation licenses in December, and awarded manufacturing and dispensary licenses last month.

The state had approved roughly 25,000 medical cannabis cards as of late January.
