How O'Fallon Patients Get Certified

Three Steps from Downtown
O'Fallon to a Missouri
Medical Marijuana ID Card

O'Fallon residents follow the standard Missouri three-step pathway. The provider handles the electronic certification submission; the patient handles the Complia application and the $28.14 state fee. From Central O'Fallon to Winghaven to Dardenne Prairie, every step is completed from home.

1

Book the Real-Time Video Visit

Schedule a video appointment with a Missouri-licensed MD, DO, or Nurse Practitioner registered with DHSS. Since December 8, 2022, NPs have been eligible to certify Missouri medical marijuana patients alongside MDs and DOs. The clinic's consultation fee is paid at booking. The visit takes place over real-time video — phone, tablet, or laptop — from anywhere in O'Fallon.

2

Provider Submits the Electronic Certification

The provider reviews your medical history against the qualifying conditions under Article XIV of the Missouri Constitution. If a qualifying condition applies, the provider completes the Electronic Physician Certification Form and submits it directly to DHSS — you do not handle the form. You receive notice that the form has been filed and have 30 days to complete your Complia application.

3

Apply & Pay on Complia

Register at the Complia patient portal, complete a New Patient application within 30 days of the certification, upload your Missouri photo ID and a digital photo, and pay the $28.14 state fee directly to DHSS. DHSS processes applications within 30 days. Your digital 3-year Patient ID card is downloaded directly from your Complia License Dashboard upon approval.

O'Fallon Patients Ask

What O'Fallon Residents
Want to Know

Direct answers — sourced from Missouri DHSS guidance — to questions O'Fallon residents ask most often about the medical card pathway.

Several practical advantages. Medical purchases are taxed at 4%, while adult-use carries a 6% state tax plus local sales taxes — often totaling 9–13% depending on the municipality. Medical card holders may purchase up to 6 ounces every 30 days (with certifying provider discretion to authorize more), compared to the 3-ounce-per-transaction limit for adult-use consumers. Medical patients also have a 60-day possession allowance versus the 3-ounce adult-use limit. Patients under 21 may participate in the medical program with parent or guardian consent — adult-use is restricted to 21 and older. Medical card holders are also afforded specific legal protections under Article XIV that do not extend to adult-use consumers.
Article XIV of the Missouri Constitution defines qualifying conditions broadly. Named conditions include cancer, epilepsy, glaucoma, intractable migraines unresponsive to other treatment, chronic conditions causing severe persistent pain or spasticity (including MS, seizures, Parkinson's, Tourette's), debilitating psychiatric disorders (including PTSD when diagnosed by a state-licensed psychiatrist), HIV/AIDS, and chronic conditions where marijuana could be a safer alternative to existing prescriptions. The constitution also includes a broad catch-all: in the professional judgment of the certifying provider, any other chronic, debilitating, or other medical condition — including hepatitis C, ALS, IBD, Crohn's, Huntington's, autism, neuropathies, sickle cell anemia, Alzheimer's agitation, cachexia, and wasting syndrome. For the official list visit health.mo.gov/safety/cannabis.
Yes. Since December 8, 2022, qualifying medical conditions may be certified by an MD, DO, or Nurse Practitioner (NP) who is licensed and in good standing with Missouri. This is a Missouri-specific expansion — many states restrict certification to MDs or DOs only. The expanded NP eligibility significantly increases scheduling availability for O'Fallon patients. All certifying professionals must be registered with the DHSS registry portal before submitting Electronic Physician Certification Forms.
Yes. Per the DHSS Patient and Consumer FAQs: "If the standard of care does not require an in-person encounter, and if the physician or nurse practitioner can conduct an exam via telemedicine in a manner that allows that physician or nurse practitioner to truthfully answer all attestations on the certification form in the affirmative, then yes, the physician or nurse practitioner may certify patients through telemedicine." Providers also comply with Missouri's telemedicine statutes at RSMo 191.1145 and 191.1146.
There are two separate, independent charges paid to two different parties. First, the clinic's consultation fee is paid at booking — that fee covers the video visit and the provider's submission of the Electronic Physician Certification Form to DHSS. The clinic does not collect any portion of the state fee. Second, a state fee of $28.14 is paid directly to DHSS — not to this clinic — when submitting the patient application on the Complia portal. The constitutional baseline is $25, adjusted annually by the Consumer Price Index per the DHSS Fee Schedule. The 3-year Patient ID card covers the full three-year validity period for one fee.
DHSS has 30 days to process patient applications, in the order received. Email updates are sent throughout. Once approved, the digital Patient ID card is downloaded directly from your Complia License Dashboard — DHSS does not mail physical cards. If an application is returned for corrections, you have 10 calendar days to resubmit with no additional fee. Importantly, if DHSS has not processed your application within 30 days, you may use the physician certification to purchase marijuana while waiting — for up to one year. This interim purchase option is unique to Missouri and provides meaningful protection against processing delays.

Missouri Medical Marijuana Card in O'Fallon — A Guide for Residents

O'Fallon Patients in Missouri's Medical Marijuana Program

O'Fallon is Missouri's fastest-growing city — a community of more than 90,000 residents in the greater St. Louis area, one of the most rapidly expanding suburban communities in the Midwest, known for its master-planned neighborhoods, excellent school districts, and easy access to the greater St. Louis metro. This platform connects O'Fallon patients with Missouri-licensed providers via telehealth.DHSS's Division of Cannabis Regulation; a Complia application completed within 30 days; and a $28.14 state fee for a 3-year digital ID card. OFallonMarijuana.clinic connects O'Fallon residents with Missouri-licensed providers via telehealth.

Missouri's Broad Qualifying Conditions Under Article XIV

Missouri's program is notably more accessible than many states because Article XIV's catch-all gives certified providers meaningful discretion: beyond the named conditions, any chronic, debilitating, or other medical condition qualifies in the provider's professional judgment. This means conditions like chronic back pain, anxiety, insomnia, neuropathy, and others that don't appear on a fixed list may still qualify after a thorough evaluation. O'Fallon patients should bring their full medical history to the video visit.

The 4% Tax Advantage

Missouri imposes a 4% state excise tax on medical marijuana purchases. Adult-use purchases carry 6% plus applicable local taxes, which frequently push the total to 9–13% depending on the municipality. For O'Fallon patients who use marijuana regularly for a qualifying condition, the tax difference alone typically covers the $28.14 state fee within the first one or two dispensary visits of a 3-year card period.

The Complia Portal and the 30-Day Application Window

After your provider submits the Electronic Certification to DHSS, you have 30 days to complete your application at the Complia patient portal. The application requires a Missouri photo ID, a digital photo, and the $28.14 state fee. DHSS reviews within 30 days — and uniquely, if DHSS hasn't processed your application within that window, Missouri law allows you to use the physician certification to purchase medical marijuana at any licensed dispensary while you wait, for up to one year.
