Missouri Cannabis Caregiver Basics
A designated caregiver in Missouri is an adult who is officially authorized to help a qualified patient purchase, possess, transport, and, when properly approved, cultivate medical cannabis. Caregivers are part of the medical program and must be approved through the state system.
Who Can Serve as a Caregiver?
- At least 21 years old
- Registered and approved as a Primary Caregiver
- Linked to one or more specific patients through state applications
Caregivers do not have to be family members. Many people designate trusted friends, adult children, or other support people who help with transportation, shopping, or daily health routines.
How Long Do Caregiver Cards Last?
As of the current rules, caregiver cards are valid for three (3) years. Patients and caregivers should track their expiration dates and renew early to avoid any gaps in authorization.
Caregiver Limits: Patients and Plant Counts
How Many Patients Can a Caregiver Assist?
A Missouri caregiver may assist up to six (6) patients. Each caregiver–patient relationship must be approved by the state and appear on your official caregiver authorization.
Caregiver Cultivation Limits (Per Stage)
If a caregiver is also approved for cultivation, they may grow cannabis for their patient(s) within the state’s plant limits. Missouri uses “stages” to describe plant types:
- Flowering plants
- Non-flowering plants
- Clones
Under current rules, a caregiver may cultivate up to 24 plants per stage MAX in their authorized grow area. However, you only get 6 plants per patient (not a typo — caregivers essentially get no additional plants for patients 5 and 6 the Math don’t Math! Lol):
- Up to 24 flowering plants
- Up to 24 non-flowering plants > 14 inches tall
- Up to 24 clones < 14 inches tall
These limits apply to the caregiver’s authorized grow space and are tied to the patients that caregiver is serving. All plants must remain within the secured cultivation area that is listed on the caregiver’s state file.
What Caregivers Can and Cannot Do
Caregivers may:
- Purchase medical cannabis for their linked patient(s)
- Possess and transport cannabis on behalf of those patients
- Grow cannabis if they hold a valid cultivation authorization
- Assist multiple patients (up to six) within state limits
Caregivers may not:
- Sell cannabis to others or operate as an unlicensed business
- Grow outside of the approved location or beyond plant limits
- Transport cannabis for people who are not officially their patients
- Share a grow space unless every plant in that space is covered by an appropriate authorization (for example, caregiver plants must be tied to linked patients, and any personal medical patient plants must be separately authorized). Consumer cultivation must be kept in a completely separate enclosed, locked area from medical cultivation.
For a broader look at rights and responsibilities, see the Rules for Patients, Caregivers, and Consumers page.
Missouri Home Cultivation Rules
Missouri allows both medical patients and licensed adult-use consumers (21+) to grow cannabis at home if they hold the proper cultivation authorization. The basic structure of plant counts is the same for each individual grower.
Individual Plant Limits (Per Stage)
A qualifying medical patient or adult-use consumer with an approved home cultivation authorization may grow
up to six (6) plants per stage:
- 6 flowering plants
- 6 non-flowering plants > 14 inches tall
- 6 clones < 14 inches tall
These limits apply per person. Where multiple authorized growers share the same residence, total plant counts may increase, but all plants must still follow Missouri’s security and visibility rules.
Location and Security Requirements
- Plants must be in a locked, enclosed space (for example, a locked room or greenhouse or locked
outdoor grow space). - Plants must not be visible from a public street or neighboring property.
- The grow must be kept at the address listed on the state authorization.
- Only authorized individuals should have access to the grow area.
Renters should also review their lease, because landlords are allowed to restrict cultivation on their property even
where state law allows it.
