A coalition of Missouri hemp businesses filed a federal lawsuit Thursday challenging a state law that would remove intoxicating hemp products from retail shelves starting November 12. The suit, filed in U.S. District Court for the Western District of Missouri, argues that House Bill 2641-signed earlier this year by Gov. Mike Kehoe-contains definitions so internally contradictory that businesses, law enforcement, and prosecutors cannot determine what is actually legal. That isn't a procedural complaint. When the same product can simultaneously qualify as "hemp" and "marijuana" under different sections of the same law, the compliance exposure is immediate and the criminal liability is real.
The plaintiffs include MNG 2005, Inc.-parent company of 55 CBD Kratom retail locations nationwide-the Missouri Hemp Trade Association, and Wisconsin-based Lifted Liquids Inc. Craig Katz, government relations and compliance manager at MNG, framed the problem plainly: legislators without deep knowledge of the cannabis supply chain produced definitions that don't hold together under operational scrutiny. Dispensary technology and compliance professionals working in markets with tightly drafted state rules-like those tracked by IndicaOnline Arizona-will recognize the pattern. When statutory language outpaces regulatory expertise, the burden falls downstream onto operators who must make SKU-level decisions about what stays on the shelf and what gets pulled. That burden, in this case, carries criminal consequences for unlicensed marijuana activity in Missouri.
Here's the catch: the law was designed, at least in part, to bring Missouri's regulatory posture in line with the federal hemp ban Congress approved last year. Rep. Dave Hinman, the bill's Republican sponsor, was direct about it-HB2641 gives state law enforcement authority to enforce the federal framework after November 12. If Congress reverses course on the federal ban, Missouri would channel any permissible intoxicating hemp products exclusively through licensed marijuana dispensaries. If Congress delays by a couple of years, the state ban would remain in place for everything except intoxicating beverages. That conditional structure is unusual, and it shifts operational risk onto retail operators who cannot predict which congressional posture will be in effect when they're making purchasing and inventory decisions.
Where the Legal Argument Centers
The coalition's core constitutional claim is vagueness-specifically, that HB2641 defines the same products as both hemp and marijuana in different provisions, which fails the basic due process requirement that regulated parties be able to understand what conduct is permitted. "Unconstitutionally vague" isn't just a rhetorical posture here; vagueness doctrine has real teeth when criminal penalties attach. The coalition's press release states it clearly: because unlicensed marijuana activity is a crime in Missouri, definitional confusion carries criminal consequences for business owners and employees operating in good faith under a hemp license.
The suit also challenges the law's treatment of interstate commerce. While the bill includes language promising not to interfere with interstate hemp transport, the coalition argues it simultaneously restricts who may transport hemp products through Missouri-a tension that raises Commerce Clause questions. And the effective date provisions, the coalition contends, are so convoluted that businesses cannot determine which specific products are covered or precisely when compliance obligations kick in. That's not a minor operational inconvenience. Without clear effective dates, inventory management decisions-what to reorder, what to return to wholesalers, what to remove from floor displays-become guesswork with legal exposure attached.
What This Means for Retail Operators Beyond Missouri
Missouri is not an isolated case. Intoxicating hemp products derived from the 2018 Farm Bill's hemp definition-including delta-8 THC, delta-10, and hemp-derived THC beverages-have existed in a regulatory gray zone across much of the country since that legislation passed. In Missouri specifically, products with THC concentrations as high as 1,000 mg have reportedly been available in smoke shops, entirely outside the licensed marijuana dispensary system. That's a number that would fail potency compliance in virtually every adult-use cannabis market in the country.
The Missouri Hemp Trade Association's president, Jay Patel, characterized the outcome of HB2641 as "the elimination of an entire legal industry coupled with a government-mandated monopoly"-a reference to the provision that would restrict intoxicating hemp products to licensed marijuana dispensaries if Congress permits their sale. For licensed dispensary operators, that channel restriction could represent a significant market expansion. For hemp retailers, smoke shops, bars, and grocery outlets currently selling THC seltzers and similar products, November 12 would effectively end that line of business under the current law.
The coalition also raised concern that imprecise definitions will sweep non-intoxicating CBD products off Missouri shelves-collateral damage that would affect a much broader category of retailers and suppliers than those selling high-potency intoxicants. That's worth watching. If a court agrees the definitions are unconstitutionally vague, a preliminary injunction could pause enforcement while the legal challenge proceeds, giving businesses some operational runway. The named defendants-Kehoe, Attorney General Catherine Hanaway, and DHSS Director Sarah Wilson-had not yet been formally served as of the filing, and both Kehoe's office and DHSS declined comment citing pending litigation.
The Compliance Clock Is Running
November 12 is close. Hemp businesses operating in Missouri need legal counsel now-not after enforcement begins. The questions are concrete: Which SKUs fall under the ban as currently written? What documentation supports a hemp designation versus a marijuana classification under the statute's competing definitions? Does transporting product through Missouri after the effective date create liability? Those aren't questions compliance teams should answer by reading the statute themselves. This is precisely the kind of regulatory ambiguity that produces enforcement actions against operators who assumed good faith was protection enough. It isn't.
What's striking here is the speed at which the federal and state frameworks are converging-and how poorly that convergence is being communicated to the retail and distribution layers that have to live with it. Operators building inventory plans, wholesale buyers placing forward orders, and logistics providers routing deliveries through Missouri all need clear rules. They don't have them yet. Whether this lawsuit produces an injunction or not, the underlying tension between an underregulated hemp market and a licensed cannabis system built around potency limits, lab testing, and chain-of-custody compliance is going to keep producing exactly this kind of legal friction-in Missouri and elsewhere.
