Federal hemp rules changed November 12. More changes are scheduled for December.

The federal definition of hemp is changing in stages, with different products affected on different dates.

The first phase took effect November 12, 2026. It excludes intermediate and final hemp-derived products containing cannabinoids that cannot be naturally produced by the cannabis plant from the federal hemp definition.

What changed in November

Congress amended the definition in November 2025. A September 2026 funding law delayed most of those amendments until December 11, but allowed the exclusions concerning cannabinoids the plant cannot naturally produce to begin November 12.

The Congressional Research Service explains that distinction in its October 28 analysis. The first phase is narrower than a ban on all hemp, CBD or hemp-derived THC products.

What is scheduled for December

Most remaining changes to the definition are scheduled to take effect December 11, 2026 under the current law. They include a total-THC standard and additional restrictions on hemp-derived cannabinoid products.

Marijuana Moment reported on November 12 that industry groups and lawmakers were continuing to seek a regulatory alternative. Those efforts do not themselves change the statutory effective date.

Hemp rules and marijuana rescheduling are separate

These amendments determine which products qualify as hemp under federal law. They are separate from DEA’s broader marijuana rescheduling proceeding and from New York’s licensing rules.
