Missouri's Hemp Flower Goes Dark Nov. 12. THC Seltzers Get 29 More Days.

On a Wednesday in early October, at Big Heads Gift Shop on Olive Boulevard in University City, Gilbert Grigsby, working the counter, rang up a bag of hemp flower for Susanna Ebert, a customer from neighboring Normandy. A few feet away, an employee named Jada Schafe was filling out labels for small packages of flower, each one listing its strength. The St. Louis Post-Dispatch photographed the scene on Oct. 7 in a store that sells hemp flower, joints, edibles and bongs to customers who never set foot in a licensed dispensary. (S5)

Nicholas Thomas, who co-owns Big Heads, already knew how the season would end. Missouri's new hemp law takes the flower off his shelves on Nov. 12, and he has started turning the University City shop into something else: trading cards and comic books first, then sneakers. "We're kind of restarting," Thomas told the Post-Dispatch. "Without hemp, a lot of our customer base is going to be upset so we're trying to transition into other stuff that our customers like." (S5)

He had already paid for the fight. State-licensed marijuana companies sued Big Heads in January for unfair competition, and Thomas said he had to find $25,000 for lawyers, which left the University City store short of inventory and killed plans for two new locations. Big Heads also runs stores in Hannibal, Missouri, and across the state line in Jacksonville, Illinois, where Missouri's law does not reach. (S5)

Thomas is one of many smoke-shop owners facing the same date. House Bill 2641, which Gov. Mike Kehoe signed on April 23, rewrites Missouri law so that any intoxicating hemp-derived cannabinoid product is legally marijuana under Article XIV of the state constitution. From Nov. 12, those products may be grown, made, tested, moved and sold only by businesses holding a Missouri marijuana license: comprehensive and medical facilities, testing labs and microbusinesses. Anyone else who sells one faces a fine of $5,000 per transaction and a class D felony, and the attorney general's office has primary jurisdiction to enforce it. (S1, S2)

The bill passed the House 126-23 and the Senate 25-5, the combined 151-28 that Kehoe cited at the signing. Read closely, though, Nov. 12 is not one deadline but two, and the gap between them was created in Washington, not Jefferson City. (S1, S3)

Congress set the original clock. The agriculture spending law enacted on Nov. 12, 2025, rewrote the federal definition of hemp to exclude finished products with more than 0.4 milligrams of total THC per container, effective a year later. Missouri's lawmakers copied that cap almost word for word into the new section 195.900, which defines an excluded final product as one holding more than four-tenths of one milligram per container of tetrahydrocannabinols, including THCA. (S1, S4)

Then Congress moved its own clock. In early September, the continuing resolution that became Public Law 119-103 pushed most of the federal hemp redefinition back to Dec. 11, 2026, according to the Congressional Research Service. Only a narrow slice, mainly cannabinoids that a cannabis plant cannot produce naturally, still turns federally illegal on Nov. 12. (S4)

HB 2641 anticipated exactly that move, and its answer is in subsection 11. Four categories become marijuana in Missouri on Nov. 12 no matter what Congress does: cannabinoids a cannabis plant cannot make; natural cannabinoids synthesized or manufactured outside the plant; anything sold as smokable or vapeable flower or bud that contains any amount of THCA; and gummies, candies, tablets, capsules, oils, baked goods and other solid edibles carrying hemp-derived delta-9 THC above the levels naturally present in the source plant. Everything else, the statute says, falls under the law only during a period in which federal restrictions prohibit it, provided it is not sold to anyone under 21. (S1)

Together, the federal delay and the Missouri carve-out sort the hemp aisle into two piles. The flower that Ebert bought on Oct. 7, and the infused gummies on smoke-shop counters, leave unlicensed shelves on Thursday, Nov. 12. A THC seltzer brewed from naturally derived hemp extract, sold to adults in a bar or grocery store, stays legal outside dispensaries until Friday, Dec. 11, when the federal definition catches up. The state's Division of Cannabis Regulation said as much in guidance it updated on Oct. 23, telling licensees that beverages with naturally occurring cannabinoids not synthesized outside the plant will not fall under Article XIV until Dec. 11. (S1, S2, S4)

That sequencing was written into the bill in April, months before Congress acted. The bill's sponsor, Rep. Dave Hinman, a Republican from O'Fallon, said it gives state police and prosecutors the power to enforce the federal ban and "brings order to an unregulated marketplace by directly mirroring federal standards." At the signing, state Sen. David Gregory held up a THC product packaged to look like Oreo cookies. Sarah Willson, director of the Department of Health and Senior Services, said children in Missouri had been hospitalized after accidentally eating unregulated products. Beverages sold to adults in bars and grocery stores were not on the statute's list of products that go first. (S6)

For licensed dispensaries the bill is mostly a gift: the products Thomas can no longer sell become products only they can. It also carries obligations. Section 195.819 bars dispensaries from creating or keeping any record with a consumer's identifying information unless the consumer agrees in writing, at $500 per violation, and the regulator has told licensees to look at delivery intake and rewards programs. A separate section makes it a class E felony for state employees to knowingly hand medical-marijuana patient information to the federal government without a subpoena or court order. Another forbids any business other than a licensed dispensary from using the word "dispensary" in its name. (S1, S2)

The industry's last formal play is in federal court. On July 16, the Missouri Hemp Trade Association, a Wisconsin hemp maker called Lifted Liquids and MNG 2005, Inc., the St. Louis company behind the CBD Kratom chain, sued Kehoe, Attorney General Catherine Hanaway and Willson in the Western District of Missouri. The case, Mohemp Trade Association v. Kehoe, was assigned to Senior District Judge M. Douglas Harpool. It argues that HB 2641 makes the same product legal hemp in one section and illegal marijuana in another, and that in a state where unlicensed marijuana activity is a crime, that confusion carries criminal consequences. (S7, S8)

The state moved to dismiss on Aug. 4. It called the suit part of a national industry campaign and said the statute settles which definition controls: a product that meets the definition of hemp and falls under none of its exclusions is not a hemp-derived cannabinoid product. "It is that simple," the motion said, as quoted by the Post-Dispatch. The plaintiffs filed their opposition on Aug. 24 and the state replied on Sept. 8. The public docket cannabis.inc reviewed, last updated Sept. 8, shows the motion fully briefed and no ruling. With 18 days to go, the shop owners quoted here are planning as if none will come. (S7, S9)

"Most judges would read [House Bill 2641] and go, 'What is going on here?'" said Chuck Hatfield, who represents the plaintiffs. "This seems like something we need to at least dig into and figure out. And that's what our clients want is a day in court." (S9)

Hinman called the lawsuit a Hail Mary. "I believe this is the last ditch effort for the hemp industry," he told the Missouri Independent in July. Hanaway, who had already been using consumer-protection law against hemp retailers before the bill passed, was blunter on signing day. (S6, S8)

“A storefront and a sales counter do not make an illegal drug operation into a legitimate business.”

— Catherine Hanaway, Attorney General of Missouri

Jay Patel, the trade association's president, framed it the other way. "This isn't consumer protection," he said when the suit was filed. "It's the elimination of an entire legal industry coupled with a government-mandated monopoly." The plaintiffs' argument is that the shops are not really being told to get a license, because the licenses they would need are a limited pool already held by marijuana companies. The market study the state released this month concluded Missouri needs no new licenses, yet it did not measure who ultimately owns the existing ones, which is the question Patel's monopoly charge turns on. (S8, S10)

Craig Katz, government relations and compliance manager for CBD Kratom and a board member of the trade association, said his chain will stock more kratom and non-alcoholic beer and may move its St. Louis-area manufacturing and warehousing out of state. With 55 stores in five states and a national wholesale arm, the company can absorb Missouri. Smaller shops cannot. "There have been many, many people who have thrown up their hands already and said, 'We can't deal with the lack of predictability,'" Katz said. (S5, S8)

Those losses are already visible. Morad Saleh closed Puzzles Hemp on St. Charles Rock Road over the summer. In O'Fallon, Michelle Noble, who owns Kratom Bunny Vape and More, said hemp is about a quarter of her sales and she plans to grow her adult-toy selection to replace it. In southeast Missouri, Jamie Turner, who opened her first Grateful Headz store five years ago, has added functional mushrooms, organic teas and bulk herbs like mullein and mugwort, which she said have sold surprisingly well. "I don't know how it will play out if I lose hemp, if it will pay my bills or not, but I'm still going to try," Turner said. (S5)

None of that changes the arithmetic on Nov. 12. Under section 195.900, each unit sold, including a single unit inside a multipack, is its own $5,000 transaction for a shop that keeps selling flower. A shop that sells only naturally derived seltzers has a 29-day window. Bills to push the federal ban back by two years have been introduced but not passed, the Congressional Research Service noted. Because Missouri's carve-out applies the state ban to those remaining products only while federal restrictions are in force, a further federal delay would, on the statute's text, stretch the reprieve as well. (S1, S4)

1. Thursday, Nov. 12, 2026: HB 2641 takes effect for THCA flower, solid edibles with added delta-9 and synthesized cannabinoids; the dispensary-name and consumer-data provisions start the same day.
2. Any day now: Judge M. Douglas Harpool can rule on the state's fully briefed motion to dismiss Mohemp Trade Association v. Kehoe.
3. Friday, Dec. 11, 2026: the delayed federal hemp definition takes effect, and with it Missouri's ban on the remaining hemp products, including beverages, unless Congress delays again.

At Big Heads, Thomas says he uses cannabis products himself and thinks people should be allowed to buy what they want. What bothers him is the picture. "The media and other people have done a really good job at painting the hemp industry as a drug dealer on the corner," he told the Post-Dispatch. "It's just not that." (S5)

The flower Grigsby rang up on Oct. 7 is the first thing the law takes. The comic books are already on the shelves, and the sneakers come next. At the Big Heads store across the state line in Jacksonville, Illinois, nothing in HB 2641 applies. (S5)
