HB 1717 Missouri House · 2026 Regular Session

Modifies provisions relating to alternative therapies and treatments, including psilocybin

HB 1717 would allow veterans aged 21+ with PTSD, major depression, substance use disorders, or end-of-life care needs to legally use psilocybin for therapeutic purposes under strict conditions. To qualify, veterans must enroll in a research study, provide physician documentation of their condition, identify a trained facilitator (a licensed mental health professional meeting specific criteria), and have psilocybin tested by a state-licensed lab. The bill prohibits state/local penalties for compliant use, requires a 150mg annual limit, and shields healthcare providers from professional discipline for participating. It also mandates a $2 million state grant for psilocybin research and annual reports on the program’s implementation. This bill is currently pending in committee and has not yet become law.

What changed between versions

Perfected Senate Committee Substitute · 4 edits
MODERATE
The bill was revised from a House version to a Senate Committee Substitute, changing the title from 'Perfected' to 'Senate Committee Substitute' and updating the bill number prefix. The core policy regarding psilocybin use for veterans and first responders remains largely the same, but the Senate version simplifies the language, removes the specific requirement for a study enrollment (replacing it with a general intent to use), and changes the facilitator training requirement from a specific curriculum to one approved by the department.
Scope change
The bill's scope regarding who can use psilocybin (veterans and first responders) and the general conditions (age, medical condition, facilitator presence) remains unchanged, though the specific requirement to enroll in a study was removed.
TECHNICAL

Updated the document header to reflect it is now a Senate Committee Substitute instead of a House Committee Substitute.

REQUIREMENT

Removed the specific requirement that the user must be enrolled in a clinical study to use psilocybin.

Changed the facilitator training requirement from a specific curriculum based on professional guidelines to a simpler requirement that the training be approved by the department of mental health.

DEFINITION

Simplified the formatting and text of the definitions for 'First responder' and 'Veteran' to remove line breaks and improve readability.
