Legislation History

The Missouri Legislature in 2014 passed HB 2238, which created the Missouri Hemp Extract Registration Program (MHERP) allows for limited patients to obtain, possess, and use low-THC hemp extract. The MHERP provides Missouri residents diagnosed with intractable epilepsy a registration card that allows legal possession, purchase, and use of CBD as an alternative form of treatment. Patients’ neurology clinicians must document the efficacy of CBD after initially recommending the alternative therapy.


SB 491 was also approved in 2014 to make the possession of ten (10) grams or less of flower marijuana a misdemeanor. The offense remains punishable by a fine. The possession of quantities greater than that are felonies In 2015, the Missouri Department of Agriculture (DOA) awarded two cultivation licenses and in 2016, the centers began serving patients.


Only patients with intractable epilepsy as documented by a neurologist, and, if they are a minor, parents or guardians responsible for their care, are eligible to participate in the MHERP. A registration Card is required to purchase CBD oil from one of two state-licensed facilities — BeLeaf Company or Noah’s Arc Foundation. In order for a patient with intractable epilepsy to be enrolled and receive a card, they must meet certain requirements. Patients enrolled in the program are allowed to purchase hemp extracts from the two state-regulated Cannabidiol Oil Care Centers.

Where is it Safe to Purchase?

MHERP cardholders are allowed to purchase low-THC hemp extract from one of the two non profit facilities licensed by the Department of Health and Senior Services (DHSS). A valid registration card is needed to obtain the CBD oil. Cards are valid for one (1) year, and there is no fee to obtain or renew a registration card, but patients must be able to prove medical need for low-THC hemp extract.

Where is it Safe to Consume?

There have been no limits or restrictions placed on a patient’s consumption of CBD. Adult use is not legal, though first-time possession of under 10 grams a misdemeanor.


Patients and their caregivers may not carry more than the legal limit of 20 fluid ounces, or 591.5 mL, of low-THC hemp extract. However, if a Missouri physician has signed a waiver, patients may legally obtain and possess more than 20 fluid ounces, or 591.5 mL, of CBD oil.


Possession, real or synthetic, of 10 grams or less of marijuana flower or synthetic marijuana is a misdemeanor. Knowingly maintaining a location where more than  35 grams of marijuana are stored, manufactured, distributed, or sold is a felony.

CBD Registry

Only patients diagnosed with intractable epilepsy are eligible to participate in the MHERP. Patients younger than 18 must register with a parent or guardian. Patients must apply for a Hemp Extract Registration Card allowing the patient to purchase CBD oil from one of two state-licensed facilities. The Division of Community and Public Health Director’s Office oversees the MHERP. Patients must also submit a completed Hemp Extract Registration Card neurologist certification form indicating that a state-licensed neurologist diagnosed the individual with intractable epilepsy, and recommends treatment with hemp extract.

Application Process

  1. Complete and submit a Missouri Hemp Registration Card application form.
  2. Submit a Missouri Hemp Extract Registration Neurologist Certification form signed by a neurologist licensed in Missouri and board certified in neurology, including proof that the clinician believes CBD may be useful to their patient
  3. Submit a copy of a valid Missouri state ID card or driver’s license for proof of age and residency.
  4. Submit a copy of a record of the neurologist’s evaluation and observation relating to the patient’s treatment for intractable epilepsy, along with medical records.

Caregiver Requirements

HB 2238 does not offer patients any legal rights or protections, nor does it define the term “caregiver.” However, a parent or legal guardian must be the registered cardholder for any patient younger than 18.

Lab Testing

HB 2238 defines “hemp extract” as less than 0.3% THC by weight, at least 5% CBD by weight, and containing no other psychoactive substances. All hemp extract must be tested to meet the maximum potency requirements.

Home Cultivation

It is illegal to cultivate cannabis for any purpose in Missouri.
