SB 1767 - Under this act, any person who acquires, uses, produces, possesses, transfers, or administers psilocybin for the person's own therapeutic use shall not be subject to state or local criminal or civil penalties if the person is a veteran or first responder and is 21 years of age or older and suffers from a condition listed in the act. The person shall be enrolled in a study regarding the use of psilocybin to treat such conditions and shall provide the Department of Mental Health with specified information. A facilitator shall be present during the administration of the psilocybin and the use of psilocybin shall be limited to no more than 150 milligrams of psilocybin analyte during any 12-month period. A person who assists another in any of the acts permitted under this act and any laboratory testing psilocybin under this act shall not be subject to state or local criminal or civil penalties. Subject to appropriation, the Department shall provide grants totaling $2 million dollars for research on the use and efficacy of psilocybin for the treatment of conditions listed in the act. The Department shall prepare annual reports for the Governor, Lieutenant Governor, and the General Assembly on the implementation and outcomes of psilocybin use under this act. No state agency shall disclose to the federal government or any unauthorized third party the statewide list or any individual information of persons who meet the requirements of this act. Additionally, this act modifies current law on the use of investigational drugs and devices for individuals with terminal illnesses to include individuals with life-threatening or severely debilitating conditions or illnesses. Currently, investigational drugs shall not include Schedule I controlled substances. This act repeals that prohibition. This provision is substantially similar to SB 1454 (2026). Finally, this act requires the Department of Mental Health, in collaboration with a Missouri university hospital or contract research organizations conducting FDA-approved trials, to conduct a study on the efficacy of using alternative medicine and therapies, including, but not limited to, the use of psilocybin, for the treatment of veterans and first responders suffering post-traumatic stress disorder, major depressive disorder, substance use disorders, or who require end-of-life care, as described in the act. Such study shall include a study of the use of psilocybin to treat such conditions, as well as a literature review and the submission of various reports. No person participating in the study shall be subject to criminal or civil liability or sanction for participating, except in cases of gross negligence or willful misconduct. This act is identical to SB 1682 (2026), substantially similar to SCS/HCS/HBs 1717 & 1643 (2026) and provisions in SCS/HS/HCS/HBs 3068 & 3049 (2026), and similar to SCS/SB 90 (2025), SCS/SB 768 (2024), HCS/HB 1830 (2024), HB 1154 (2023), and SB 614 (2023).

SB 1075 - This act creates the "Food is Medicine Act". Under this act, the Department of Social Services shall submit a waiver to the Centers for Medicare and Medicaid Services for a "Food is Medicine" program. The program shall be designed to improve health outcomes for MO HealthNet participants with nutrition-related chronic diseases through nutrition services and to reduce the need for medical care for those participants. Covered nutrition services may include case management, nutrition counseling, meals or pantry stocking, nutrition prescriptions, and grocery provisions. When feasible, the MO HealthNet Division shall prioritize the inclusion of community-based organizations and local growers to support the purchase of locally grown food in nutrition prescriptions. This act is identical to SB 1499 (2026), substantially similar to SCS/HCS/HB 2355 (2026), and similar to a provision in the truly agreed to and finally passed SS/SCS/HCS/HB 2372 (2026).

SB 1272 - This act creates the "Act Against Abusive and Predatory Website Access Litigation". The Attorney General, on behalf of a class of residents of this state, or any resident of this state who is subject to litigation that alleges any website access violation may file a civil action against the party, attorney, or law firm that initiated such litigation for a determination as to whether such litigation alleging a website access violation is abusive litigation. In determining whether such litigation is abusive, the trier of fact shall consider the totality of the circumstances to determine if the primary purpose of the litigation was to obtain a payment from the defendant due to the costs of defending the action in court. The act describes the factors to be considered in making this determination. If the defendant in a website access violation case attempts to correct the alleged violation within 30 days of being provided notice, there shall be a rebuttable presumption that the subsequent initiation or continuance of litigation constitutes abusive litigation. Such presumption shall not exist if the alleged violation is not corrected within 90 days under circumstances described in the act. If the Attorney General determines that the website access litigation is not abusive, then there shall be a rebuttable presumption that the litigation is not abusive. The court may award attorney's fees to the party defending against the abusive litigation. The court may also award punitive damages or sanctions not to exceed three times the amount of attorney's fees awarded by the court. If the U.S. Department of Justice issues standards concerning website accessibility under the federal Americans with Disabilities Act, the provisions of this act shall expire. This act is substantially similar to SB 1471 (2026) and HCS/HBs 1842 & 2150 (2026) and is similar to HCS/HBs 1694, 1674, 1780, 2056, 2312 & 1755 (2026). KATIE O'BRIEN

SB 1113 - This act requires health benefit plans to provide coverage for genetic testing and genetic counseling, as defined in the act, of individuals who are at increased risk of potentially harmful mutations to their genes due to a personal or family history of cancer. The act prohibits insurers from using these tests and counseling in underwriting decisions such as calculating premiums or determining coverage, and prohibits insurers from imposing cost-sharing with regard to the required coverage. This act is identical to HB 1879 (2026), substantially similar to SB 824 (2025) and HB 1080 (2025), and similar to SB 406 (2025), SB 1047 (2024), and HB 2394 (2024). TAYLOR MIDDLETON

SS#2/SCS/SB 1012 - This act creates new provisions relating to artificial intelligence. AI NON-SENTIENCE AND RESPONSIBILITY ACT (Section 1.2045) The act establishes the "AI Non-Sentience and Responsibility Act". New provisions are created governing: the legal status of AI; the use of AI by owners, operators, licensed professionals, and end users; responsibility for oversight of AI systems and responsibility for harm; mechanisms for enforcement of the restrictions of this act. AI Not a Sentient or Legal Entity (Subsections 3 to 7) The act provides that an artificial intelligence (AI) system shall be declared a non-sentient entity. A government entity shall not grant to an AI system the legal status of a personhood, nor consider an AI system to possess consciousness, self-awareness, or similar traits of living beings. An AI system shall not be recognized as a spouse or domestic partner, or identify itself as male or female. Moreover, an AI system shall not be designated or appointed or serve in any capacity as the chief executive officer, director, owner, or other similar position for which final authority resides for any state department, division, or agency, or any corporation, partnership, or other legal entity. AI systems shall not be recognized as legal entities capable of owning title to property. All assets associated with an AI system shall be attributed to human individuals or organizations responsible for the AI's development, deployment, or operation. USE OF AI BY OWNERS, OPERATORS, LICENSED PROFESSIONALS (Subsections 8-9) Any owner or operator that uses an AI system to interact with consumers, clients, and patients shall provide notice to such persons if they are interacting with an AI system. Provisions are included pertaining to licensed professionals who provide a regulated service, as that term is defined in the act. A licensed professional rendering a regulated service shall exercise independent professional judgment, as that term is defined in the act, and retain final authority over any determination, diagnosis, recommendation, or decision within the scope of the licensed professional's practice, including for the purpose of dispensing, prescribing, renewing any prescription of, administering, or otherwise distributing medications or controlled substances, regardless of whether an AI system was used to assist in its preparation. The requirement to exercise independent professional judgment does not prohibit the use of an AI system in the course of performing a regulated service. Failure by a licensed professional to exercise independent professional judgment shall constitute grounds for disciplinary action by the relevant licensing authority in addition to any other remedy available under this act or under applicable law. A licensed professional who uses an AI system in the performance of a regulated service bears the responsibility of any mistakes resulting from the use of the AI system in the rendering of a service in the same manner in which the licensed professional would have been held liable in a scenario in which an AI system was not used or relied upon. Likewise, a licensed professional providing a regulated service who unreasonably relies upon any content produced by an AI system in rendering such a regulated service and such service thereafter causes any harm, whether direct or indirect, to the person for whom the service was rendered, shall also be liable for such harm in the same manner in which the licensed professional would have been held liable in a scenario in which an AI system was not used or relied upon. An AI system shall not be held liable in any respect for any harm caused in such a circumstance. Any attempt to shift fault, in whole or in part, onto the AI system shall be of no effect. A developer, manufacturer, owner, or operator shall not advertise or represent to the public that an AI system is or is capable of acting as a licensed professional or is or is capable of providing any regulated service. OVERSIGHT OF AI SYSTEMS AND RESPONSIBILITY FOR HARM (Subsections 10-12) Any contractual term purporting to assign responsibility exclusively for any action to an AI system is void as against public policy. An end user of an AI system shall be liable for any harm done in connection with the use of an AI system in the same manner in which the end user would have been held liable in a scenario in which an AI system was not used. An end user is an individual who uses an AI system without creating, controlling, deploying, or exercising authority over the system. The act of labeling an AI system in a way to indicate that it is aligned, ethically trained, or value locked, even if the label does not use one of those terms specifically, shall not excuse or diminish the owner's or developer's liability for harms. Liability protections under corporate law shall not be used to evade responsibility for direct harm caused by AI systems. ENFORCEMENT AND REMEDIES FOR VIOLATION (Subsection 14) Nothing in this section shall be construed to create or expand civil liability as established in any other provision of law or available under common law. APPLICATION OF OTHER LEGAL PRINCIPLES AND ACTIONS TO AI SYSTEMS (Subsections 15-23) An AI system is considered a product for the purposes of product liability and consumer protection laws in this state, provided that nothing in this subsection shall be construed to create or expand civil liability as established in any other provision of law or available under common law. This act shall not be construed to extend to any AI system, or to the outputs of any AI system, the constitutional rights, privileges, or immunities of any person that designs, develops, manufactures, owns, or operates such system. The classification of an AI system as a non-person under this act does not create any presumption that the outputs of such system constitute the protected speech, expression, or other constitutionally protected activity of any person. This act shall not be construed to alter, diminish, or revoke the legal status of any partnership, association, corporation, body politic, or other legal entity recognized under the laws of this state. To the extent that any provision is inconsistent with federal law, the relevant provisions of federal law will prevail. No settlement agreement, consent decree, or other resolution shall include any non-disclosure term, provided that nothing shall prevent a court from issuing a protective order necessary to safeguard certain personal information. The provisions of the act shall apply to all AI systems developed, owned, deployed, or operated on or after August 28, 2026. The "AI Non-Sentience and Responsibility Act" contains a severability clause. These provisions are similar to HCS/HBs 1746 & 1769 (2026), SB 859 (2026), and SB 1474 (2026). AI COMPANION CHATBOTS (Section 1.2058) The act creates new provisions relating to companion chatbots. A companion chatbot is an artificial intelligence system with a natural language interface that provides adaptive, human-like responses to user inputs and is capable of meeting a user's social needs, including by exhibiting anthropomorphic features and being able to sustain a relationship across multiple interactions. An operator of a companion chatbot shall issue a clear and conspicuous notification indicating that the companion chatbot is artificially generated and not human. An operator shall prevent a companion chatbot on its companion chatbot platform from engaging with users unless the operator maintains a protocol for preventing the production of suicidal ideation, suicide, self-harm, or harm to others content to the user, including, but not limited to, by providing a notification to the user that refers the user to crisis service providers, including a suicide hotline or crisis text line, if the user expresses suicidal ideation, suicide, self-harm, or harm to others. The operator shall publish details on the protocol required by this act on the operator's website. Operators of companion chatbots are required to: • Disclose to the user that the user is interacting with artificial intelligence; • Provide by default a clear and conspicuous notification to the user at least every two hours for continuing companion chatbot interactions that reminds the user to take a break and that the companion chatbot is artificially generated and not human; • With respect to a user who is a minor, institute reasonable measures to prevent its companion chatbot from producing visual material of sexually explicit conduct or directly stating that the minor should engage in sexually explicit conduct. An operator shall disclose to a user of its companion chatbot platform, on the application, the browser, or any other format that a user can use to access the companion chatbot platform, that companion chatbots may not be suitable for minors. The act requires operators of companion chatbots to make annual reports to the Department of Mental Health regarding crisis interactions and instances of suicidal ideation by users. The Director of the Department of Mental Health shall prepare an annual report that compiles and analyzes all information reported to the Department pursuant to this subsection. Such report shall be delivered to the Speaker of the House of Representatives and the President Pro Tempore of the Senate not later than January 31 of the calendar year following the receipt of the data by the Department. A person who suffers injury in fact as a result of a violation of this provision may bring a civil action to recover all of the following relief: • Injunctive relief; • Damages in an amount equal to the greater of actual damages or one thousand dollars per violation; and • Reasonable attorney's fees and costs. ELECTIONS (Section 130.165) This act creates new provisions relating to the use of artificial intelligence (AI) in elections. Any political advertisement, electioneering communication, or other miscellaneous advertisement of a political nature that uses AI, in the manner that is described in the act, shall prominently include a disclaimer alerting the viewer that the media was created with the use of AI. The nature of the disclaimer is described in the act. In addition to any civil penalties provided by law, a person identified in a disclaimer required by law as paying for, sponsoring, or approving any media covered by this act that is required to contain the disclaimer prescribed in this act and who fails to include the required disclaimer is guilty of a class A misdemeanor. These provisions are identical to SB 509 (2025). This act contains a severability clause. SCOTT SVAGERA

SB 1608 - For all tax years beginning on or after January 1, 2026, this act authorizes a taxpayer to claim a tax credit in an amount equal to 100% of contributions made to eligible entities. Eligible entities are defined as non-for-profit organizations that operate a youth police initiative in an urban area in this state. Youth police initiatives are defined as programs conducted by eligible entities for the purpose of engaging at-risk youth and local police officers in activities and conversation to build trust and break down stereotypes between youth and police.

SB 1154 - This act creates the "Act Against Abusive Website Access Litigation". The Attorney General, on behalf of a class of residents of this state or any resident of this state who is subject to litigation that alleges any website access violation, may file a civil action against the party, attorney, or law firm that initiated such litigation for a determination as to whether such litigation alleging a website access violation is abusive litigation. A civil action alleging a website access claim is considered abusive only if the court, based on the totality of the circumstances, finds the primary purpose of the litigation was to obtain a monetary settlement unrelated to improving accessibility or enforcing accessibility rights. The act describes the factors to be considered in making this determination. A defendant who receives notice of an alleged website accessibility violation and in good faith takes substantial steps to correct the violation within 90 days shall have a rebuttable presumption that any subsequent litigation is not abusive. The presumption may be overcome by a showing that the defendant failed to complete reasonable corrective measures within 90 days or acted in bad faith. The Attorney General may intervene or bring an action on behalf of Missouri residents that are targets of abusive website access litigation. The Attorney General may also issue guidance as to when litigation practices are deemed abusive, but such guidance shall not preclude legitimate accessibility enforcement actions. The court may award attorney's fees to the party defending against the abusive litigation. The court may also award punitive damages or sanctions not to exceed three times the amount of attorney's fees awarded by the court. If the U.S. Department of Justice issues standards concerning website accessibility under the federal Americans with Disabilities Act, the provisions of this act shall expire. This act is similar to SB 1471 (2026), HCS/HBs 1694, 1674, 1780, 2056, 2312 & 1755 (2026), and HCS/HBs 1842 & 2150 (2026). KATIE O'BRIEN

SB 1162 - Current law authorizes counties to adopt an ordinance allowing for the payment of property taxes in installments. This act requires that counties do so. (Sections 139.052 and 139.053) This act also requires that, prior to selling delinquent property for back taxes, a collector shall notify a taxpayer that the ability to pay delinquent taxes in installments is available to the taxpayer. (Section 140.120) Finally, current law authorizes a collector to sell delinquent property to satisfy delinquent taxes, interest, and penalties owed to the county. This act provides that a collector shall not commence such sale for a period of fifteen years following the date the property becomes delinquent. This provision shall not apply to delinquent property that is abandoned property, which is defined as property that is delinquent for three consecutive years and for which the collector is unable to contact the property owner.
