A provision signed into law in November 2025 rewrites the federal definition of hemp. When it takes effect, the great majority of intoxicating hemp products sold today stop being legal hemp. This page explains what changes, which products are affected, and what remains available where you live.
Update, September 2026: a stopgap funding bill signed September 2, 2026 (H.R. 6500) pushed the total-THC standard and the 0.4 milligram per-container cap back 30 days, from November 12 to December 11, 2026. One piece kept the original date: products containing cannabinoids the cannabis plant cannot naturally produce, such as THC-O and other lab-made acetates, lose federal hemp status on November 12, 2026.
The 2018 Farm Bill defined hemp as cannabis containing no more than 0.3% delta-9 THC by dry weight. That measured one molecule. The new definition measures total THC, which folds in THCA and other THC isomers. A plant that passed the old test by holding its THC in acid form does not pass the new one.
This is the provision that does most of the work, and the one fewest people know about. It is not a percentage, it is an absolute quantity per finished package. A 5 milligram gummy fails. A can of THC seltzer fails. A full-spectrum CBD tincture that nobody would call intoxicating can fail as well, simply because a whole bottle adds up.
Anything falling outside the revised definition stops being hemp in the eyes of federal law and is treated as a controlled substance. Industry attorneys have estimated that roughly 95% of the hemp cannabinoid products on shelves today sit outside the new line.
| Product | Status |
|---|---|
| THCA flower and pre-rolls | Leaves the hemp definition |
| Delta-8 THC | Leaves the hemp definition |
| Delta-10 THC | Leaves the hemp definition |
| HHC (hexahydrocannabinol) | Leaves the hemp definition |
| THC-O and other novel acetates | Leaves the hemp definition |
| Hemp-derived delta-9 gummies and edibles | Leaves the hemp definition |
| THC seltzers and hemp beverages | Leaves the hemp definition |
| Hemp vapes and cartridges | Leaves the hemp definition |
| Full-spectrum CBD oil | Partly affected |
| Industrial hemp: fiber, grain and seed oil | Not affected |
Industrial hemp grown for fiber, grain and seed oil is specifically preserved. Broad-spectrum CBD and CBD isolate with negligible THC can remain inside the definition. And nothing here touches state-licensed cannabis: dispensaries in legal states operate under state law and are unaffected by the hemp provisions.
Possibly. Legislation has been introduced to preserve a regulated hemp market rather than a prohibition, and the hemp industry is lobbying hard for a delay or a carve-out. The only change enacted so far is the 30-day delay in H.R. 6500. Until something else passes, December 11, 2026 is the operative date for the total-THC standard and the per-container cap, and businesses are planning around it.
The federal change is nationwide, but your alternatives are not. In a state with a licensed market, the licensed channel is simply still there. In a state without one, there may be no legal replacement at all. Pick your state for a straight answer.
