Frequently asked questions
What is Section 781?
Section 781 of P.L. 119-37 rewrites the federal hemp definition. Among other changes it sets a cap of 0.4 mg total THC per container for finished hemp products starting December 11, 2026.
Does Section 781 affect minor cannabinoids like CBG and CBN?
It can. Finished products are judged on total THC per container and synthetic cannabinoids are excluded, so check each formula and its COA rather than assuming a cannabinoid is exempt.
How is total THC calculated?
Total THC is Delta-9 THC plus THCA multiplied by 0.877, which accounts for the weight lost when THCA converts to THC. Our total THC guide has worked examples.
Is this legal advice?
No. These guides explain the rules in plain terms. Confirm your own products and state rules with a qualified attorney.
