Nov. 12: synthetic cannabinoids leave federal hemp, and Illinois, Missouri and Vermont rewrite their rules
Nov. 12 is the first of two federal hemp deadlines. It reaches synthetics, not THCA flower, but three states use it to change what may be sold and by whom.
The short answer. On Nov. 12, 2026, cannabinoids that cannot be naturally produced by the cannabis plant lose federal hemp status. THCA flower does not; its federal date is Dec. 11. The same day, as of Oct. 3, Illinois moves intoxicating hemp into its cannabis law, Missouri’s HB 2641 takes effect, and Vermont realigns its hemp definition.
WASHINGTON — Nov. 12 was supposed to be the one day the federal hemp market changed. H.R. 6500, signed Sept. 2, split it in two. Products made from what the plant grows got until Dec. 11. A narrower group did not.
The federal piece: what the carve-out covers
The stopgap kept Nov. 12 for synthetic cannabinoids “that are not capable of being naturally produced by a Cannabis sativa L. plant,” in the bill’s language as quoted by Foley Hoag and the Texas Hemp Business Council. Section 781 of Public Law 119-37 also excludes cannabinoids the plant can make but that were “synthesized or manufactured outside the plant,” per the Congressional Research Service.
The text sorts the two groups. That second exclusion is subclause (II) of the statute, and the stopgap holds Nov. 12 only for subclause (I) (P.L. 119-37, sec. 781; H.R. 6500, Sec. 2019). Delta-8 THC sold in stores is usually converted from CBD in a reactor, but delta-8 itself occurs in the plant in trace amounts, so it is a cannabinoid the plant is capable of producing. Converted delta-8 therefore falls under subclause (II) and waits for Dec. 11. It would move to Nov. 12 only if the FDA’s list of naturally occurring cannabinoids found delta-8 not capable of being naturally produced. The FDA was told to publish a list of naturally occurring cannabinoids by Feb. 10, 2026; as of Sept. 3 it had not, according to Hemp Law Group, and the desk found no list as of Oct. 3.
For THCA flower, nothing federal changes on Nov. 12. THCA is made by the plant. Until Dec. 10 flower is still judged by its delta-9 line. The Dec. 11 change is covered on the Hemp Ban Tracker.
Three states move on Nov. 12
| State | Law | What starts Nov. 12 | Hemp lane for THCA flower |
|---|---|---|---|
| Illinois | SB 3222, signed June 12 | Intoxicating hemp regulated under the Cannabis Regulation and Tax Act; 0.4 mg total THC per container for final products; new statutory hemp definition | Moves into the licensed channel |
| Missouri | HB 2641, signed April 23 | Intoxicating hemp sold only by marijuana licensees; 0.4 mg cap; 21+ | Closes to non-licensees (date partly tied to federal law) |
| Vermont | Cannabis Control Board realignment | State hemp definition realigned with the federal one | Already closed; total-THC math applies |
Illinois
Gov. JB Pritzker signed SB 3222 on June 12. Sales of intoxicating hemp to anyone under 21 were banned immediately. From November, those products fall under the Cannabis Regulation and Tax Act, with child-resistant packaging and marketing rules, according to the governor’s office and the Illinois Department of Agriculture’s overview. The new Illinois Hemp Act defines hemp from Nov. 12 and caps final products at 0.4 mg of total THC per container. Illinois has licensed adult-use stores, which continue to sell high-THC flower. See the Illinois State Page.
Missouri
Gov. Mike Kehoe signed HB 2641 on April 23. It makes intoxicating hemp a product that only entities with Missouri marijuana licenses may cultivate, make, transport or sell, with a 0.4 mg cap and a 21+ rule (Missouri Independent; bill summary).
The date is less tidy than it looks. Some provisions apply only while the federal restriction is in force, and after H.R. 6500 that restriction reaches naturally derived products on Dec. 11. In July the MoHemp Trade Association, Wisconsin manufacturer Lifted Liquids and St. Louis retailer MNG 2005 sued in the U.S. District Court for the Western District of Missouri, arguing the law conflicts with federal law and contradicts itself, and asking the court to stop it before Nov. 12 (Bev Info Group, July 20). The desk found no ruling as of Oct. 3. Missouri is the only state with a date set to move its hemp lane from open to closed this fall; see the Missouri State Page.
Vermont
Vermont already applies total-THC math, so high-THCA flower has been closed to its hemp lane. In April 8 testimony to the House Agriculture Committee, the Cannabis Control Board described a realignment with the federal hemp definition on Nov. 12. Whether that realignment now follows the federal split, Nov. 12 for synthetics and Dec. 11 for the rest, is not addressed in anything the desk has found. See the Vermont State Page.
The rest of the November calendar
| Date | What happens |
|---|---|
| Nov. 1 | Oklahoma: hemp beverages become 21+ |
| Nov. 3 | Election; see our ballot report |
| Nov. 12 | Federal synthetics date; Illinois, Missouri, Vermont |
| Nov. 13 | New Jersey’s hemp-beverage sell window closes |
| Dec. 11 | Federal total-THC rule reaches THCA flower |
The desk will update this report if a court rules in the Missouri case or if any agency publishes the cannabinoid list before Nov. 12.

Questions readers asked
What happens on Nov. 12, 2026?
Cannabinoids that are not capable of being naturally produced by the cannabis plant lose federal hemp status. Illinois moves intoxicating hemp under its Cannabis Regulation and Tax Act, Missouri's HB 2641 takes effect, and Vermont realigns its hemp definition. THCA flower's federal date is Dec. 11.
Is delta-8 banned on Nov. 12?
Not on the enrolled text, as of Oct. 3, 2026. The Nov. 12 date covers only cannabinoids the plant cannot naturally produce. Delta-8 occurs in the plant, so delta-8 converted from CBD is a plant cannabinoid 'synthesized or manufactured outside the plant,' a category that loses federal hemp status on Dec. 11. That changes only if the FDA's overdue list finds delta-8 not capable of being naturally produced.
Can I still buy THCA flower in Missouri after Nov. 12?
HB 2641 makes intoxicating hemp a product only marijuana licensees may sell, starting Nov. 12. Some provisions are tied to the federal restriction, which may point to Dec. 11, and a federal lawsuit challenges the law. Missouri's licensed dispensaries continue to sell marijuana flower.
