Section 781, signed into law in November 2025, redefines what counts as legal hemp using a total THC standard that includes THCA and delta-8 THC. When enforcement begins on November 12, 2026, an estimated 95% of hemp-derived cannabinoid products currently on the market will become illegal overnight. Here is what consumers need to understand.
What Changed
The 2018 Farm Bill defined hemp as cannabis containing less than 0.3% delta-9 THC by dry weight. This definition created a loophole that allowed manufacturers to produce products containing THCA, delta-8 THC, and other cannabinoids that were technically legal because they were not delta-9 THC.
Section 781 closes that loophole by switching to a total THC standard. Under the new rules, all forms of THC — including THCA, delta-8, delta-10, and THC-O — count toward the 0.3% limit. Additionally, finished products are capped at 0.4mg total THC per container, a limit so low that most current hemp products cannot comply.
What Disappears
The U.S. Hemp Roundtable estimates that Section 781 will eliminate roughly 95% of hemp-derived cannabinoid products currently sold in the United States. This includes most delta-8 gummies, THCA flower, hemp-derived vape cartridges, and full-spectrum CBD products that contain trace amounts of THC above the new limit.
The economic impact is staggering. The hemp-derived cannabinoid market generates an estimated $30 billion in annual revenue and supports roughly 300,000 jobs. States that have built regulatory frameworks and tax structures around legal hemp products stand to lose over $1.5 billion in combined tax revenue.
What Is Being Done
The 2026 Farm Bill draft includes provisions that would soften the impact of Section 781, but the bill is still working through committee. Hemp industry groups are lobbying for a higher THC threshold and a longer transition period. Several states have announced they will not enforce federal hemp restrictions, setting up potential conflicts with federal agencies.
Legal challenges are also expected. Industry groups argue that Section 781 was passed without adequate public comment and that the 0.4mg per container limit is arbitrary and scientifically unsupported.
What You Can Do
If you use hemp-derived products, now is the time to contact your representatives. The Farm Bill is the vehicle most likely to fix Section 781, but it needs support from both parties. Organizations like the U.S. Hemp Roundtable and National Hemp Association are coordinating advocacy efforts and can point you to your local representatives.
The November deadline is real. The industry has eight months to convince Congress to change course — or watch most of the legal hemp market disappear.
