Missouri House HB 1717, 2026 session
Proposal: last listed action May 7, 2026
The official tracker lists placement on the informal calendar and marks final agreement and sending to the governor incomplete. The displayed August 28, 2026 date is a proposed effective date, not proof of enactment.
Proposals and limits of this check
HB 1717 concerns alternative therapies, including psilocybin. The reviewed bill tracker does not establish an enacted access program. Do not infer that a person qualifies for treatment, that a provider is licensed, or that a product can be shipped to Missouri from the bill summary.
The sources above concern psilocybin and related controlled-substance provisions. They do not resolve the legality of every mushroom species, food, extract or advertised “microdose” product. An online listing or a seller's willingness to ship does not establish legal access.
Before relying on a legal summary
Read the current official text, including exceptions and effective dates. A rule in another state or country does not transfer automatically across a border. For advice about your own circumstances, consult a qualified lawyer. This page is educational and does not recommend products, providers or ways to obtain controlled substances.
