Legislative History

The Missouri state legislature in 2014 passed HB 2238, which allows for certain patients to obtain, possess, and use low-THC hemp extract and created the Missouri Hemp Extract Registration Program (MHERP). The MHERP provides Missouri residents, diagnosed with intractable epilepsy, a registration card that allows them to legally possess and use CBD as an alternative form of treatment.


In 2014, additional legislation was approved to decriminalize the possession of ten (10) grams or less of flower marijuana. The offense remains a criminal misdemeanor punishable by a fine. The possession of greater quantities carry serious legal consequences, including jail or prison time. 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 and their caregivers are eligible to participate in the program. The Missouri Hemp Extract Registration Card is required to purchase CBD oil from one of the two state-licensed facilities. 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 two state-regulated Cannabidiol Oil Care Centers.

Where is it Safe to Purchase?

Missouri Hemp Extract Registration cardholders are allowed to purchase low-THC hemp extract from one of the two non profit facilities licensed by the DOA. A valid registration card is needed to obtain the CBD oil. Cards are valid for one year, and there is no fee to obtain or renew a registration card.

Where is it Safe to Consume?

There have been no limits or restrictions placed on patient consumption.


Patients and their caregivers may not carry more than the legal limit of 20 ounces, or 591.47 mL, of low-THC hemp extract. However, if a Missouri physician has signed a waiver, patients may legal obtain and possess more than 20 fluid ounces, or 591.47 mL, of CBD oil.

CBD Registry

Only patients diagnosed with intractable epilepsy are eligible to participate in the program. 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 the two facilities licensed by the DOA. 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. Completed 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.
  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.

Caregiver Requirements

HB 2238 does not offer 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 minor patient.

Lab Testing

HB 2238 defines “hemp extract” as an resin, oil or tincture that has at least 5% CBD and no more than 0.3% THC. All hemp extract must be tested to meet the maximum potency requirements.
