Who can serve as a Missouri caregiver?

Under Missouri program rules, a caregiver must be at least 21 years old, a Missouri resident, and pass a background check. Most disqualifying offenses are violent felonies and drug-trafficking convictions; check the Missouri Department of Health and Senior Services (DHSS), Division of Cannabis Regulation caregiver policy for the current disqualification list. Caregivers must be designated by a registered patient (or, for a minor, by the patient's parent or legal guardian) and listed on the patient's registration.

Patient-to-caregiver ratio in Missouri

Missouri permits up to 3 patients per caregiver. The ratio is set in state rules and may be adjusted by the legislature; verify the current limit on the Missouri Department of Health and Senior Services (DHSS), Division of Cannabis Regulation website before applying.

Missouri caregiver application steps

  1. Get designated by a patient. The patient (or their parent/guardian) names you as caregiver on their Missouri Department of Health and Senior Services (DHSS), Division of Cannabis Regulation registration.
  2. Complete the caregiver application. Submit your information through the Missouri Department of Health and Senior Services (DHSS), Division of Cannabis Regulation portal, including identification and proof of Missouri residency.
  3. Pay the caregiver fee. The fee varies — many Missouri caregivers pay a fee comparable to the patient registration fee. Check the Missouri Department of Health and Senior Services (DHSS), Division of Cannabis Regulation schedule.
  4. Pass the background check. Missouri runs state and FBI checks. Disqualifying offenses are listed in the program rules.
  5. Receive your caregiver card. Carry it whenever transporting cannabis or accompanying the patient to a dispensary.
