Full Breakdown

Missouri's Constitution (Amendment 3, Art. XIV, § 2) legalized adult-use cannabis statewide, and Clay County cannot prohibit personal home cultivation. An adult 21 or older who obtains a registration card from the Department of Health and Senior Services, for a $100 annual fee, may grow up to six flowering plants, six nonflowering plants, and six clones. Plants must be kept at one private residence in a locked, enclosed space not visible from a public place, and labeled with the grower's name and card number. Two registered adults in a household may each grow, but combined plants stay in one enclosed space. Growing without a card, or for sale, remains unlawful.

Violations & Fines

Cultivating without a registration card, exceeding the plant limits, or growing in an unlocked or publicly visible space can bring civil penalties and loss of the cultivation privilege; growing for unlicensed sale is a criminal offense.
