Becoming a Patient as a Minor:

Individuals under the age of 18 who wish to become patients will go through a similar process as their adult counterparts with two minor changes: First, Two separate physician certifications are required for minor patients. Second, there will also be a parental or legal guardian consent form which includes acknowledgements that the signatory will serve as the minor patient's primary caregiver and will bear the responsibility of purchasing and administering medicine.

Benefits of Being a Patient:

You will have an affirmative defense in court if arrested for cannabis possession. If you require an organ transplant, as a registered patient, you will not be turned away because of your cannabis use.

Becoming a Caregiver:

Caregivers must be at least 21 years of age. To start the process, have a registered patient complete a caregiver authorization form. Patients may designate up to two caregivers this way, each caregiver may serve up to three patients. Caregivers will then make an account on the Missouri health portal and complete their application online. Be sure to have all of the same documents listed or patients above.

Out of State Patients:

The state of Missouri does not recognize out of state patient registrations.

Home Cultivation:

Patients over the age of 18 with valid registry ID cards may pay an extra $100 fee to be allowed to grow up to six flowering plants. Two individuals with valid patient IDs in one household may grow up to twelve flowering plants; both patients will have to pay separate home cultivation fees. Since the law specifies a maximum number of flowering plants, an individual could theoretically have an unlimited number of plants in the vegetative stage.

Your patient application will also include the following if you plan to grow at home:

  1. The address of the facility in which you will cultivate cannabis.
  2. A description of the security arrangements and processes that will be used to restrict access to only qualifying patients and their primary caregivers.
  3. If cultivation space will be shared with another patient: The name and patient license number of that patient must also be provided.
  4. A statement affirming your agreement to immediately make available access to your cultivation if the department requests an inspection and that your cultivation will take place in a secured and locked area.

Cannabis Expungement:

Although cannabis expungement has not occurred in Missouri, Amendment 3 was passed in 2022 to legalize marijuana use for adults. This prevents individuals from being subject to criminal prosecution and began movements towards cannabis expungement in the state of Missouri.
