Missouri's Hemp Law Survives Court Challenge: What Changes Nov 12

Table of Contents

    On Thursday, November 12, a big part of the Missouri hemp shelf goes away. Smokable hemp flower with any THCA, gummies and other edibles with delta-9 THC above natural plant levels, and anything made with synthetic cannabinoids move under the state's marijuana licensing system. If your local shop doesn't hold one of those licenses, it can't sell them.

    Hemp businesses went to federal court to stop that. On Wednesday, November 4, they lost. The same day, Missouri's attorney general announced lawsuits against four retailers.

    Here's what the judge decided, what changes next week, and why we think Missouri is solving the wrong problem.

    What the judge decided

    The case is MoHemp Trade Association v. Kehoe, No. 2:26-cv-04170, in the U.S. District Court for the Western District of Missouri. The plaintiffs were the MoHemp Trade Association, Wisconsin-based Lifted Liquids, and St. Louis-based MNG 2005. They sued Gov. Mike Kehoe and other state officials in July, arguing that HB 2641 is unconstitutionally vague, discriminates against out-of-state businesses, and is preempted by the 2018 Farm Bill.

    In an 18-page order dated November 4, Senior District Judge M. Douglas Harpool granted the state's motion to dismiss on all three counts. On preemption, he wrote: "The Court finds that HB 2641 is not preempted by the 2018 Farm Bill." On vagueness, he found the law is not facially vague and that the plaintiffs hadn't shown it was vague as applied to them. On the commerce clause, he ruled the plaintiffs lacked standing and added that the restrictions "apply equally to Missouri and non-Missouri entities."

    Much of the ruling turned on timing. Because the law hadn't taken effect, the judge wrote, "Plaintiffs ask the Court to assume an interpretation of HB 2641 that the State has never adopted or enforced against anyone, much less against Plaintiffs. This makes Plaintiffs' claims premature." He also denied the request for a preliminary injunction as moot.

    One line in the order is worth reading twice. On the licensing question, the court wrote: "The fact that no licenses remain to be given out by DHSS equally limits in-state and out-of-state would-be sellers." Put plainly, a hemp shop that wants to keep selling these products can't simply apply for a license.

    The order doesn't say whether the dismissal is with or without prejudice, and we found no appeal reported as of November 6. The plaintiffs could still take the case to the Eighth Circuit.

    What leaves Missouri shelves on November 12

    The new law, Section 195.900, calls itself the Intoxicating Cannabinoid Control Act. Starting November 12, it covers hemp-derived cannabinoid products that:

    • contain cannabinoids the plant can't produce naturally, or natural cannabinoids synthesized outside the plant;
    • are sold as smokable or vapeable flower or bud and contain any amount of THCA;
    • are gummies, candies, capsules, oils, baked goods or other solid edibles with hemp-derived delta-9 THC above the levels naturally found in the source plant.

    Covered products are treated as marijuana. Under the law, the "cultivation, production, manufacturing, testing, transportation, and retail sale" of hemp-derived cannabinoid products must be handled only by businesses licensed under the state's marijuana framework. Under subsection 10 of the statute, a violation carries a fine of $5,000 per transaction and is a class D felony.

    Other hemp-derived products follow a different clock. Because Congress moved the federal date, the statute applies to them "only during any period in which such federal restrictions prohibit such products," and in the meantime they can't be sold to anyone under 21. We walked through the full rulebook in our October rundown of HB 2641.

    Four lawsuits, filed the same day

    On November 4, Attorney General Catherine Hanaway announced suits against four retailers in Aurora, Des Peres, Independence and Rock Port. Her office alleges they sold products over legal THC limits as federally legal hemp, and that some presented themselves as licensed marijuana retailers. The state is seeking civil penalties and injunctions, and it wants three of the locations declared "drug-den public nuisances."

    "Missourians deserve honesty and legality from the businesses operating in their communities," Hanaway said in the release.

    These are allegations. None has been proven in court, and we aren't naming the shops. If a store really did sell over-limit product while posing as a licensed seller, that's the kind of bad actor we want enforcement to catch.

    The timing still matters. The judge called the challenge premature in part because the state hadn't enforced the law against anyone. The lawsuits were announced the same day, and Hanaway told the Missouri Independent, "You're going to see more lawsuits." If more suits follow, the fight moves from what the law says on paper to how the state actually uses it.

    How the December 11 federal deadline stacks on top

    Missouri isn't the only clock. Under federal law, two dates matter, according to an October 28 Congressional Research Service legal sidebar:

    November 12: products containing cannabinoids "not capable of being naturally produced by the cannabis plant" lose federal hemp status. We covered what that means in our November 12 synthetics explainer, and we don't defend those products.

    Friday, December 11: the rest of the new federal hemp definition takes effect, including a cap of 0.4 milligrams of total THC and other cannabinoids with similar effects, combined, per container, as described in CRS report IF13136. That cap hits every state, Missouri included, unless Congress acts first.

    So a Missouri shopper faces a state cutoff next Thursday and a federal one on December 11.

    Rules work better than lawsuits

    We've said it from the start. Ban the synthetic stuff. Keep products away from anyone under 21. Require lab testing and honest labels. Go after the shops that lie about what's in the package.

    Missouri chose a different path. It folded hemp products into a licensing system the court itself says has no licenses left to give, then started suing. That leaves farmers, makers and shop owners who want to follow the rules with no way to keep selling these products.

    A clear hemp framework, with real age limits, testing and enforcement, would protect consumers without wiping out an industry. Regulate it. Don't eliminate it.
