- Creates provisions relating to the regulation of industrial hemp-derived consumable products
- SS/SB 904 - This act modifies the definition of "industrial hemp" in statute, as well as adds a definition of "hemp" and removes a definition of "illegal industrial hemp". Under this act, no state agency or state employee shall disclose any personally identifying information of persons who have applied for or obtained a qualifying patient identification card, a qualifying patient cultivation identification card, or primary caregiver identification card for medical marijuana to the federal government or any federal employee, or other unauthorized third party, unless required to do so pursuant to a subpoena or court order issued by a court. Any person who knowingly violates this act shall be guilty of a class E felony. Upon the written request of a consumer, a marijuana dispensary shall not create or retain any record containing a consumer's identifying information. This provision shall not apply to any constitutionally-mandated record-keeping requirements relating to qualifying patients and primary caregivers. Dispensary facilities that violate the provisions of this act shall be assessed a $2,500 fine per occurrence. These provisions are substantially similar to SS/SCS/SB 54 (2025). This act establishes the "Intoxicating Cannabinoid Control Act". Under this act, intoxicating hemp-derived products shall be considered marijuana and regulated as marijuana is regulated by the Department of Health and Senior Services under the Missouri Constitution. The cultivation, production, manufacturing, testing, transportation, and retail sale within Missouri of all intoxicating hemp-derived products shall be conducted solely by licensed comprehensive, medical, testing, and marijuana microbusiness facilities. The Attorney General, the Department of Health and Senior Services, the Department of Public Safety, prosecuting and circuit attorneys, and other state agencies shall collaborate to enforce these provisions as described in the act. Hemp and industrial hemp shall not be subject to regulation under these provisions. No person or entity engaged in the sale of cannabidol (CBD), hemp, marijuana, cannabinoids, hemp-derived cannabinoid products, or related paraphernalia, other than a comprehensive or medical marijuana dispensary facility or a microbusiness dispensary facility, shall carry on, conduct, or transact business under a name that contains as part of the name the word "dispensary". Any person or entity in violation of these provisions shall be guilty of a class D felony and subject to an administrative fine of $5000 per transaction, as described in the act. These provisions are similar to provisions in SS/SCS/SB 54 (2025). SARAH HASKINS
