An Active Legislative Landscape
Missouri's cannabis laws are constitutionally protected through Amendment 3, meaning the legislature cannot repeal recreational cannabis. But lawmakers can still pass bills that affect adjacent areas — hemp regulation, public consumption penalties, medical access on college campuses, and criminal justice reforms. Several significant pieces of legislation are active or recently resolved.
The Hemp Battle — Resolved (April 23, 2026)
The most contentious cannabis-related fight in Missouri did not involve marijuana at all — it involved hemp-derived THC products (Delta-8, Delta-9 edibles, THC-O, etc.) that competed with the regulated cannabis market. After more than two years of cease-and-desist actions and stalled legislation, Gov. Mike Kehoe signed the intoxicating-hemp ban into law on April 23, 2026.
Kehoe Signs Hemp Ban (April 23, 2026)
Sponsored by Sen. David Gregory (R-Chesterfield), the bill bans intoxicating hemp products effective November 12, 2026 — aligned with the federal hemp cliff under PL 119-37 § 781. The legislation also added provisions protecting marijuana-consumer privacy and securing cannabis workers’ right to organize. State DHSS Director Sarah Willson cited cases of children accidentally hospitalized by unregulated hemp THC products in supporting the ban.
Earlier Enforcement Campaign
The April 2026 signing followed a multi-year enforcement campaign. AG Catherine Hanaway, who took office in September 2025, expanded the prior 33 cease-and-desist letters and approximately 60 store lawsuits using consumer-protection statutes. The enforcement campaign laid the political groundwork that brought the bill across the finish line.
What Now
From November 12, 2026 forward, intoxicating hemp products may no longer be sold in Missouri convenience stores, gas stations, smoke shops, or any other unlicensed retail outlet. Sellers face civil and potentially criminal penalties under the new law. The licensed Amendment-3 cannabis market becomes the only legal route to intoxicating cannabis products in the state. Operators with current intoxicating-hemp inventory should plan sell-through by the November 11, 2026 deadline.
SB 1187: Re-Criminalize Public Consumption
SB 1187 seeks to strengthen penalties for public cannabis consumption. Under current law (Amendment 3), first-offense public consumption is a civil fine of up to $100. SB 1187 would increase penalties and potentially re-criminalize what is currently a civil infraction.
Opponents argue that re-criminalizing public consumption would disproportionately affect homeless individuals and people who lack access to private property for legal consumption. Supporters argue that stronger penalties are needed to deter public use, particularly in parks, near schools, and on public transit.
HB 1896: Cannabis Early Release
HB 1896 addresses individuals currently incarcerated for cannabis offenses. The bill would create a pathway for early release for people serving sentences for cannabis crimes that are no longer illegal or that would receive lesser penalties under current law.
Amendment 3 identified 565 individuals on probation or parole eligible for sentence review, but HB 1896 extends the discussion to those still incarcerated. The bill connects to Missouri's broader expungement and justice efforts.
HB 1898: Campus Medical Cannabis
HB 1898 would allow registered medical cannabis patients to use cannabis on college campuses. Currently, most Missouri universities prohibit cannabis on campus regardless of the user's medical status, citing federal funding requirements (campuses that receive federal funding must comply with the Drug-Free Schools and Communities Act).
The bill attempts to balance patient access with federal compliance concerns, potentially creating a framework where medical patients can use cannabis in designated areas or private dormitory rooms while universities maintain compliance with federal requirements.
Ballot Initiative: Eliminate License Caps
A filed ballot initiative led by Andrew Thampy proposes sweeping changes to Missouri cannabis law:
- Eliminate all license caps — removing the limits on dispensary (216), cultivation (65), and manufacturing (88) licenses
- Eliminate possession limits — removing the 3-ounce-per-transaction cap
- 10-year tax structure — adjustments to the existing tax framework
If the initiative gathers sufficient signatures and passes, it would represent the most dramatic change to Missouri's cannabis framework since Amendment 3. Existing operators, particularly those who invested based on limited-license economics, would face a fundamentally different competitive landscape.
Federal Developments
Rescheduling Executive Order (December 2025)
In December 2025, a federal executive order directed the DEA to reschedule cannabis from Schedule I to a lower classification. While rescheduling would not legalize cannabis federally, it would have significant implications for Missouri businesses, including potential relief from Section 280E (which prevents cannabis businesses from deducting standard business expenses on federal tax returns).
SAFER Banking Act
The SAFER Banking Act (formerly SAFE Banking) continues to advance through Congress. If enacted, it would allow banks and credit unions to serve cannabis businesses without fear of federal penalties. For Missouri operators who rely heavily on cash transactions, SAFER Banking would be transformative — reducing security risks, enabling credit card payments, and lowering the cost of doing business.
What to Watch
- Hemp regulation: The outcome of HB 2641/SB 54 and AG enforcement will shape the competitive landscape for licensed cannabis businesses
- Microbusiness Round 3: Following March 2026 rule reforms, the next lottery round is expected in 2026
- Federal rescheduling: Potential 280E relief would significantly improve cannabis business economics
- Thampy ballot initiative: If it qualifies, it would be the most consequential cannabis measure since Amendment 3
