Status: Active
Action: 2026-03-11 – Placed on Informal Calendar
Pending: Missouri Senate floor / perfection calendar
Summary
Would make 7-hydroxymitragynine (7-OH) in amounts concentrated above 400 parts per million on a dry-weight basis a Schedule I controlled substance in Missouri. The official Missouri Senate summary says the bill is identical to HB 1614. (Missouri Senate)
Useful Government Page
The most useful government page right now is the official Missouri Senate bill page, because it gives the bill summary and links back to the main bill-tracking materials. The committee minutes page is also useful because it confirms the February 17 hearing and the February 23 committee vote. (Missouri Senate)
Public Testimony / Hearing
I did not find a currently posted public testimony submission page for SB 1605. The official Missouri Senate committee minutes page shows the hearing already happened on February 17, 2026, and the bill is now sitting on the Informal Calendar, so direct contact with Senate offices is the main pressure route right now.

I think it wouldn’t hurt at all to contact the members on this committee and tell them we want to keep 7 safe, legal, and even suggest using the Haven Access Regulations in place of a ban!
