Federal Hemp THC Ban: What Changes November 12 and December 11, 2026
The short version: A federal law passed in November 2025 rewrites what counts as legal hemp. It takes effect in two steps. On November 12, 2026, products made with cannabinoids the plant cannot produce on its own stop counting as hemp. On December 11, 2026, the bigger change hits: a total-THC test that counts THCA, and a cap of 0.4 milligrams of THC per container for finished products. Most delta-8, delta-10 and THCA flower products sold today will not fit under the new rules.
Published November 10, 2026. This is general information, not legal advice. Federal and state rules are changing quickly, so check the sources below before you buy, sell or travel.
What law is this?
The change comes from a provision in Public Law 119-37, the funding and extensions package signed on November 12, 2025, which ended that fall’s government shutdown. The provision amends the federal definition of hemp that the 2018 Farm Bill created. It was written to take effect 365 days after enactment, which is November 12, 2026.
In September 2026, Congress passed a stopgap funding law, the Continuing Appropriations and Extensions Act, 2027, signed on September 2. It pushed most of the hemp changes back to December 11, 2026. It did not delay the part about cannabinoids the plant can’t make naturally, so that piece still starts on November 12.
What changes on November 12, 2026
Products that contain cannabinoids “not capable of being naturally produced” by the cannabis plant are no longer hemp under federal law. In plain terms, this targets lab-made or chemically created cannabinoids.
Which products fall in this group is not fully settled. The law relies on a list of naturally produced cannabinoids from the FDA, and as of late September 2026, the Congressional Research Service reported that list had not been published. Some products, such as HHC and THC-O, are widely expected to be caught. Delta-8 is the one people argue about most: it occurs naturally in tiny amounts, but almost all delta-8 on store shelves is made by chemically converting CBD. Either way, delta-8 products are caught by the December 11 rules below.
What changes on December 11, 2026
- Total THC, not just delta-9. Hemp must test at no more than 0.3% total THC on a dry-weight basis, and total THC includes THCA. This is the change that ends “THCA flower,” which was sold as hemp because it tested low in delta-9 THC even though it becomes regular THC when you smoke it.
- A 0.4 mg cap per container. A finished hemp product can’t contain more than 0.4 milligrams of combined total THC and other cannabinoids with similar effects. That limit is for the whole container, not per serving. For comparison, many hemp gummies sold today contain 5 to 10 milligrams of THC each.
- A limit for in-between products. Extracts and other intermediate products are capped at 0.3% combined total THC and similar cannabinoids, and they can’t be sold directly to consumers.
- Cannabinoids made outside the plant. Products made with cannabinoids that were synthesized or produced outside the plant are excluded, even if the same compound occurs in nature.
- Seeds. Viable seeds from plants above 0.3% total THC no longer count as hemp.
What this means if you buy hemp products
- Delta-8, delta-10, THC-O and HHC: expect them to disappear from gas stations, smoke shops and websites in states that don’t regulate them separately.
- THCA flower and pre-rolls: these count as marijuana under federal law once total THC is measured.
- Hemp THC drinks and gummies: most current products are far above 0.4 mg per container, so most will not qualify as hemp.
- CBD: the law does not ban CBD by name. CBD isolate and broad-spectrum products with essentially no THC should be fine. Full-spectrum CBD depends on how much THC is in the whole bottle.
- Legal-weed states: licensed dispensary marijuana is regulated by state law and isn’t affected by this change. Some states may also move hemp-THC products into their own licensed systems. Check your state’s marijuana law guide.
Products that lose their hemp status are treated as marijuana under federal law. In states where marijuana is illegal, the state’s marijuana penalties may also apply. Don’t stock up thinking an old receipt will protect you.
Could the dates change again?
Possibly, but nothing has passed yet. As of early November 2026, several bills were sitting in Congress:
- H.R. 7024 and S. 3686: a two-year delay, to November 2028.
- H.R. 6209: a repeal that would restore the 2018 hemp definition.
- H.R. 9830: would regulate consumable hemp products instead of banning them.
December 11 is also the day the current stopgap funding expires, so hemp could come up again in the next funding fight. We’ll update this post if anything changes.
Bottom line
If you use delta-8, THCA flower or hemp THC gummies, plan on them being hard to find legally after December 11, 2026. In a state with legal adult-use marijuana, licensed dispensaries are the clear legal option. New to cannabis? Start with our state-by-state marijuana law hub to see what’s allowed where you live.
