Missouri's hemp THC ban just got dragged into federal court

Missouri's ban on intoxicating hemp products has a court date. A coalition of hemp businesses — MNG 2005 Inc., the parent of 55 CBD Kratom stores across five states, along with the Missouri Hemp Trade Association and Wisconsin-based Lifted Liquids — filed a federal lawsuit in the Western District of Missouri asking a judge to block HB 2641 before it takes effect November 12. The defendants are Gov. Mike Kehoe, who signed the ban April 23, Attorney General Catherine Hanaway, and state health director Sarah Wilson.

The legal theory comes in three parts: the law's definitions of "hemp" and "marijuana" are unconstitutionally vague; it violates the dormant Commerce Clause by favoring in-state cultivation and manufacturing; and it's preempted by the 2018 Farm Bill's protections for interstate hemp transport. Association president Jay Patel put the industry's framing bluntly — this isn't consumer protection, it's the elimination of a legal industry paired with what he called a government-mandated monopoly.

The stakes are wider than Missouri. THC seltzers in bars, restaurants, and convenience stores have become the hemp industry's mainstream beachhead, and states keep reaching for outright bans rather than regulation. Whether vagueness, Commerce Clause, and Farm Bill preemption arguments can actually stop a state ban is exactly the question operators in Tennessee, North Carolina, and Texas need answered — and this case is now the live test.

If you sell hemp-derived THC in Missouri, November 12 is still the date on the wall until a judge says otherwise. Watch for a preliminary-injunction ruling; that's the tell for whether this playbook travels to other states.
