Clay County Cannabis – Is It Legal & Where To Buy 2024

Is Cannabis Cultivation Legal in Clay County?

Adult and medical use of marijuana are both legal in Clay County. Following the approval of Amendment 2 in 2018, qualifying patients or caregivers with medical marijuana cards and cultivation identification cards may cultivate medical marijuana in an enclosed and locked shared space. A limit of 12 flowering marijuana plants, 12 nonflowering plants, and 12 clones may be grown by two individuals (either two patients, a patient and a caregiver, or two caregivers). However, if one of the two individuals is a registered patient and caregiver, a maximum of 18 flowering marijuana plants, 18 nonflowering plants, and 18 clones may be cultivated.

Medical Marijuana Cultivation Facilities are licensed by the Section for Medical Marijuana Regulation (SMMR) to cultivate marijuana commercially. Cultivation may be done indoors, outdoors, or in greenhouses. As of January 2023, Clay County has six cultivation facilities located mainly in the cities of Kansas and Smithville that operate under the following conditions:

  • The facility should be 1,000 feet away from any daycare, elementary or secondary school, or church. Appropriate security and surveillance systems must be installed inside and outside the facility to prevent unauthorized access.

  • Outdoor cultivation may only be allowed if the area is not easily seen in public and the facility has an exterior barrier around the cultivation area. A fence at least eight feet tall and made out of six gauge metal or a stronger link topped with a razor wire is required. A total of 2,800 flowering plants may be cultivated outdoors.

  • Indoor cultivation may have a maximum flowering plant canopy space of 30,000 square feet. On the other hand, greenhouses using both natural and artificial lighting may grow up to 2,800 flowering plants or have a maximum of 30,000 square feet of flowering plant canopy space.

While the approval of Amendment 3 in December 2022 legalized the adult use of marijuana, Clay County residents will still have to wait until February 2023 to apply for a consumer personal cultivation identification card. Moreover, marijuana may only be available for consumers to purchase on the same date after licensed medical facilities (cultivators, manufacturers, dispensaries, and transporters) convert their licenses to comprehensive facilities.
