Missouri medical marijuana card FAQ

To qualify for a medical cannabis certification in Missouri, patients must meet several requirements:

Age: To be eligible for a medical cannabis certification in Missouri, patients must be at least 18 years old. For patients under 18, a parent or legal guardian, aged at least 21, can act as their caregiver and apply on their behalf.

Residency Requirement: Effective from December 8, 2022, applicants are no longer required to provide proof of Missouri residency.

Medical Condition: Patients seeking a medical card must have a qualifying medical condition as outlined by Missouri law.

Physician's Certification: All applications require an MD, DO, or nurse practitioner certification issued within the last 30 days, submitted on behalf of the qualifying patient. This certification confirms that the patient has a qualifying medical condition as defined by Missouri law.

Patient Registry and Certification: Once certified by a qualified medical professional, patients must complete the application process through the Missouri Department of Health and Senior Services (DHSS) online portal. The patient's information and physician certification are submitted to the DHSS, and upon approval, the patient is added to the state's medical cannabis registry. The certification is an essential component for legal access to medical cannabis in Missouri.

Medical marijuana ID cards in Missouri are valid for a period of three years for applications processed on or after December 8, 2022. Upon the next approved renewal after this date, the ID cards will also be valid for three years.

Consumer personal cultivation identification cards are valid for 12 months from the date of issuance and can be renewed.

Patients eligible for medical marijuana should understand that selecting a primary caregiver means entrusting them to purchase and possess medical cannabis on their behalf. This decision rests solely with the patient, who retains the authority to designate or revoke a caregiver's status. When choosing a caregiver, patients should consider factors similar to those involved in entrusting someone with other personal medical responsibilities and overall well-being.

To apply for a patient ID card in Missouri, you'll need to provide the following documentation:

1. Physician or nurse practitioner certification: This certification, dated less than 30 days before application, must be submitted by a qualified healthcare provider on behalf of the patient, confirming their qualifying medical condition.
2. Government-issued photo identification card: A legible copy of the patient's government-issued photo ID is required.
3. Clear, color digital photo: A clear, color digital photo of the applicant's face, where their features are clearly visible, is necessary.

Your medical cannabis certification must be renewed every three years to maintain legal access to medical cannabis in Missouri. Be sure to check the expiration date on your current license to ensure timely renewal.

The renewal window for submitting a patient or caregiver state application opens no sooner than 60 days prior to the expiration date. It's essential to wait 24 hours after receiving a 60-day renewal notification before submitting the application through the state registry. To maintain uninterrupted access, we recommend applying no less than 30 days before expiration. This timeframe allows ample time for obtaining a new physician certification form, submitting the application, and processing it before the license expires. While the system permits submission within 30 days of expiration, the Department requires 30 days to process applications and cannot guarantee processing before the card expires if submitted within this timeframe.

Under Article XIV, approved Patient ID card holders, or Caregiver ID card holders acting on behalf of licensed patients, may purchase up to 6 ounces of dried, processed marijuana or its equivalent within a 30-day period, unless certified by a physician or nurse practitioner for a greater amount.
