Missouri Defends Hemp Product Ban Against Industry Lawsuit

August 29, 2026

Missouri's attorney general spent late August 2026 asking a federal judge to toss out a lawsuit that could decide whether thousands of gas stations, bars, and grocery stores across the state have to pull THC seltzers and hemp gummies off their shelves in a matter of weeks. The law at the center of the fight, HB 2641, bans intoxicating hemp products statewide starting November 12, 2026 -- a deadline that's now barreling toward retailers who built entire product lines around drinks and edibles that were legal to sell just months ago.

The plaintiffs challenging the law aren't fringe players. The MoHemp Trade Association, Wisconsin-based manufacturer Lifted Liquids, and St. Louis retailer MNG 2005 -- which runs 55 stores spread across five states -- argue the statute's core definitions are so muddled that nobody can say with confidence what's actually still legal to sell. And the timing couldn't be stranger: just as Missouri barrels toward its cutoff date, Congress is moving in the opposite direction, delaying the very federal hemp THC ban that Missouri's law was designed to mirror.

What HB 2641 Actually Does

HB 2641 landed on Gov. Mike Kehoe's desk as one of his first bills signed this year, and it takes full effect on November 12, 2026. The law's practical effect is blunt: it strips intoxicating hemp products, including the THC seltzers that have become fixtures behind convenience store counters and grocery coolers, off the market statewide. No more selling a hemp-derived beverage next to the beer case or stocking gummies at a gas station register.

Under the new rules, hemp-derived products can only be sold by businesses holding one of Missouri's capped marijuana licenses issued through the Department of Health and Senior Services. That sounds like a regulatory pathway on paper, but in practice it's a dead end for most existing hemp companies -- those licenses are limited in number, already allocated, and effectively closed off to businesses that built their operations around hemp rather than the state's licensed marijuana program. For companies like Lifted Liquids, there's no realistic route to compliance; the license they'd need simply isn't available to them.

Rep. Dave Hinman (R-O'Fallon), who sponsored the bill, has framed it as a necessary corrective -- a last-ditch attempt to bring order to a hemp market he and other lawmakers see as having grown with essentially no oversight. That framing echoes a broader trend playing out at the federal level, since HB 2641 largely mirrors the federal hemp THC ban Congress approved last year. Missouri wasn't inventing a new regulatory approach so much as adopting the same intoxicating-hemp crackdown that's been spreading through state legislatures and Congress alike, betting that state and federal timelines would line up cleanly.

The Lawsuit: Vague Definitions, Real Businesses

The lawsuit landed in the U.S. District Court for the Western District of Missouri on Thursday, July 16, 2026, well ahead of the law's effective date, precisely so plaintiffs could ask the court to strike it down before retailers are forced to act. The named plaintiffs -- MoHemp Trade Association, Lifted Liquids, and MNG 2005 -- represent a cross-section of the industry HB 2641 hits hardest: trade advocates, manufacturers, and a multi-state retail chain with real inventory and real employees on the line.

Their central argument isn't that Missouri lacks authority to regulate hemp -- it's that the law's actual language doesn't tell anyone clearly what's banned. The complaint contends that HB 2641's definitions of hemp and marijuana overlap in ways that leave retailers guessing whether a given product is legal hemp or now-prohibited marijuana under state law. For a convenience store chain stocking hundreds of SKUs, that kind of ambiguity isn't an academic concern -- it's the difference between staying open and facing enforcement action over a product nobody can definitively classify.

The suit names Gov. Kehoe, Attorney General Catherine Hanaway, and DHSS Director Sarah Wilson as defendants, with Hanaway drawing particular attention since her office is tasked with enforcing the ban once it takes effect. The plaintiffs are asking the court to declare the law unconstitutional on vagueness grounds before the November 12 deadline arrives, which would let stores keep selling their current inventory while the underlying legal question gets sorted out -- assuming the judge agrees there's a real constitutional problem to sort out in the first place.

Missouri's Motion to Dismiss

Missouri's attorney general's office filed a motion earlier this month asking Judge M. Douglas Harpool to dismiss the case outright, and the state's argument leans heavily on precedent rather than novelty. Attorneys for the state describe the plaintiffs' vagueness theory as a familiar playbook -- one that hemp industry groups have run against similar laws in other states, with courts repeatedly declining to buy it. The state's filing points to other federal cases where comparable challenges to hemp restrictions failed, framing this lawsuit as more of the same rather than a genuinely novel constitutional question.

On the substance, Missouri insists there's no contradiction baked into the statute at all. The state's position is that HB 2641 explicitly resolves the overlap plaintiffs are complaining about: any product that meets the definition of a hemp-derived cannabinoid is simply treated as marijuana under the law, full stop. No ambiguity, the state argues -- just a clear rule that closes what plaintiffs are calling a loophole but that the state calls a deliberate design choice.

Plaintiffs aren't conceding the point. Attorney Chuck Hatfield pushed back this week, arguing that the statutory language is confusing enough that most judges reading it cold would struggle to say definitively what's prohibited and what isn't -- which is exactly the kind of uncertainty vagueness doctrine is supposed to guard against. With briefing now largely complete, the case sits with Judge Harpool, and every week that passes without a ruling narrows the window for retailers hoping for relief before the November 12 cutoff.

A Moving Federal Target

While Missouri's case works its way through federal court, Congress has been quietly moving the goalposts on the federal side of this equation. The U.S. Senate approved a funding measure that pushes back the federal hemp THC ban to December 11, 2026 -- a full month later than originally planned, and notably a month after Missouri's own deadline. That measure still needs to clear the U.S. House and get signed before it's final, so nothing is locked in yet, but the direction is clear: federal lawmakers are giving the hemp industry more runway, not less.

That leaves Missouri in an odd spot. HB 2641's November 12 effective date was set specifically to track the federal ban's original timeline, on the theory that state and federal restrictions would kick in together. Instead, if the Senate's delay holds, Missouri will end up banning intoxicating hemp products nearly a month before federal law does the same thing. The rationale lawmakers used to justify the timing -- alignment with Washington -- is at risk of evaporating before the ink on the state law even matters.

It's a small mismatch in some ways, a matter of weeks, but it captures something bigger about where the hemp industry stands right now. Retailers, manufacturers, and trade groups are trying to plan around rules that are shifting at both the state and federal level simultaneously, often in opposite directions on the calendar. A business that assumed it had until federal law changed to adjust its inventory might discover its home state moved the deadline up on its own, timing be damned.

Everything now hinges on what Judge Harpool decides. If he denies Missouri's motion to dismiss and lets the case proceed toward a substantive ruling on the merits, retailers could get breathing room past November 12 while the vagueness question gets fully litigated. If he grants the motion, HB 2641 takes effect on schedule and hemp businesses without a capped marijuana license lose their legal footing in Missouri almost overnight.

Either way, this case is a clean illustration of a problem that's bigger than Missouri. Lawmakers wrote HB 2641's deadline to shadow a federal ban that Congress is now actively delaying, which means the state built its entire enforcement timeline around a moving target it doesn't control. That's not a one-off quirk -- it's the predictable result of state legislatures racing to mirror federal hemp policy while federal hemp policy itself stays unsettled.

Missouri isn't an isolated case, either. Similar hemp THC bans and similar industry lawsuits are working through courts in multiple states right now, each with its own definitions, deadlines, and enforcement quirks. Anyone buying, selling, or manufacturing hemp-derived THC products -- in Missouri or anywhere else -- should treat this as a reminder to check current state law before assuming a product on the shelf today will still be legal next month. The rules are genuinely in flux, and confirming local law directly, rather than relying on what was true even a few weeks ago, is the only safe approach right now.
