TL;DR
H.R. 5371 replaces the Delta-9-only hemp standard with a total-THC standard effective November 12, 2026. Most current THCA flower and high-potency products will be reclassified.
On November 12, 2025, Congress passed the Continuing Appropriations and Extensions Act (H.R. 5371), which included a provision that fundamentally rewrites the federal definition of hemp. Section 781 of the law replaces the 2018 Farm Bill's Delta-9-only standard with a total THC standard that includes THCA, caps finished products at 0.4 mg total THC per container, and excludes synthetic cannabinoids from the hemp definition entirely. These changes take effect on November 12, 2026 — exactly one year after the law was signed.
The implications are massive. Industry groups estimate that approximately 95% of existing hemp-derived cannabinoid products will become non-compliant once the law takes effect. For consumers who rely on THCA flower, Delta 9 gummies, and other hemp-derived THC products, understanding what's changing — and what efforts are underway to change or delay it — is critical.
What the 2018 Farm Bill Allowed
The Agriculture Improvement Act of 2018 (the 2018 Farm Bill) defined hemp as Cannabis sativa L. with a Delta-9 THC concentration of not more than 0.3% by dry weight. This definition removed hemp from the Controlled Substances Act, legalizing the cultivation, sale, and possession of hemp and hemp-derived products nationwide.
The key detail: the 2018 definition measured only Delta-9 THC. It did not account for THCA, Delta-8 THC, or other cannabinoids. This created the legal framework that allowed THCA flower — which contains high levels of THCA but less than 0.3% Delta-9 THC — to be sold as legal hemp. It also enabled the Delta 9 gummy market, where edibles contain measured doses of Delta-9 THC within the dry-weight limit.
What H.R. 5371 Changes
Section 781 of H.R. 5371 makes three fundamental changes to the hemp definition:
1. Delta-9 becomes total THC. Hemp is now defined by its "total tetrahydrocannabinols concentration (including THCA)" rather than just Delta-9 THC. The 0.3% threshold remains, but it now applies to the combined total of Delta-9 THC, THCA, and any other cannabinoids that the FDA determines have similar effects to THC. This means THCA flower testing at 25% THCA is calculated at approximately 22% total THC — well above the 0.3% limit.
2. Finished products capped at 0.4 mg per container. Any final hemp-derived cannabinoid product intended for human use through ingestion, inhalation, or topical application must contain no more than 0.4 milligrams of total THC per container. A "container" is defined as the innermost packaging that directly holds the product. This limit is extraordinarily restrictive — a standard 10 mg Delta 9 gummy contains 25 times the allowed amount. Even low-dose products and many CBD formulations with trace THC could exceed this threshold.
3. Synthetic and converted cannabinoids excluded. Products containing cannabinoids that are synthesized or chemically converted from other cannabinoids (such as Delta-8 THC converted from CBD) are excluded from the definition of hemp entirely. These products would be classified as marijuana under the Controlled Substances Act.
What Products Are Affected
If enforced as written, the 0.4 mg per container limit would affect virtually every intoxicating hemp product currently on the market:
THCA flower, pre-rolls, and concentrates — Already exceeded the total THC threshold. These products become non-compliant under both the total THC percentage test and the 0.4 mg container limit.
Delta 9 gummies and edibles — Currently legal under the dry-weight calculation, but the 0.4 mg per container cap would make a standard 10 mg gummy non-compliant by a factor of 25x. This is the provision that distinguishes the federal law from state-level total THC rules like the ones Texas adopted in March 2026 — the federal version goes much further.
Delta-8 and other converted cannabinoids — Explicitly excluded from the hemp definition regardless of THC content.
CBD products with trace THC — Full-spectrum CBD products containing even small amounts of THC could be affected by the 0.4 mg container limit, depending on how "container" is defined in FDA guidance.
Non-intoxicating hemp products — Industrial hemp (fiber, grain, seed oil), CBD isolate products with no detectable THC, and agricultural hemp operations remain legal under the revised definition.
The Legislative Fight to Change It
Multiple legislative efforts are underway to repeal, delay, or replace Section 781 before the November 2026 deadline:
The American Hemp Protection Act (H.R. 6209) — Introduced in November 2025 by Rep. Nancy Mace (R-SC) with bipartisan co-sponsors including Reps. Massie (R-KY), Lofgren (D-CA), and Baird (R-IN). The bill would strike Section 781 in its entirety, restoring the 2018 Farm Bill definition. Critics note it proposes no replacement regulatory framework.
The Hemp Planting Predictability Act (H.R. 7024) — Introduced in January 2026 by Rep. Baird (R-IN) with bipartisan support. This bill would delay the implementation of Section 781 rather than repeal it, giving Congress more time to develop a regulatory framework.
The Cannabinoid Safety and Regulation Act (CSRA) — Introduced in the Senate by Senators Wyden (D-OR) and Merkley (D-OR) in December 2025. This 84-page bill would replace the Section 781 prohibition with a federal regulatory framework including THC limits of 5 mg per serving and 50 mg per container for edibles, a federal minimum purchase age of 21, mandatory third-party testing, and standardized packaging requirements. The CSRA would preserve state authority to impose stricter regulations.
2026 Farm Bill Reauthorization — The 2018 Farm Bill was extended through September 30, 2026 by H.R. 5371 itself. The Farm Bill reauthorization process represents another vehicle for hemp industry amendments. House Agriculture Committee Chairman Glenn Thompson filed an 802-page draft of the Farm, Food, and National Security Act of 2026 in February. Hemp stakeholders are working to attach provisions that would override Section 781 before it takes effect.
The political calculus is significant: 2026 is a midterm election year with voting on November 5 — one week before the Section 781 enforcement date. Industry groups are actively leveraging this timing, particularly in rural districts with significant hemp economies.

What Consumers Should Do Now
The situation is genuinely fluid. The federal law as written would effectively end the intoxicating hemp market, but there is active bipartisan legislative effort to repeal or replace it, and the political dynamics of a midterm election year create additional pressure for congressional action.
In the meantime, hemp-derived products remain federally legal under the current 2018 Farm Bill framework until November 12, 2026. THCA flower, pre-rolls, vapes, concentrates, and Delta 9 edibles can still be purchased in states where they are permitted under current law.
The Haze Connect will continue operating under the current legal framework while monitoring every legislative and regulatory development. We recommend consumers build their understanding of the issue now, support advocacy organizations working to preserve legal access to hemp-derived products, and stay informed through sources covering the topic closely.

Frequently Asked Questions
Is THCA flower still legal federally?
Yes — until November 12, 2026. Under the current 2018 Farm Bill framework, THCA flower containing less than 0.3% Delta-9 THC by dry weight remains federally legal hemp. The Section 781 changes that redefine hemp using total THC do not take effect until the one-year anniversary of the law's passage.
Will Delta 9 gummies be affected by the federal law?
If Section 781 takes effect as written, yes. The 0.4 mg total THC per container limit would make virtually all current Delta 9 gummy products non-compliant. This is why legislative efforts to repeal or modify Section 781 are critical — the CSRA bill, for example, would allow up to 50 mg per container for edibles.
What is the most likely outcome?
The hemp industry, multiple members of Congress from both parties, and advocacy organizations are actively working to repeal, delay, or replace Section 781 before November 2026. The Farm Bill reauthorization process and midterm election dynamics create political incentives for congressional action. However, there is no guarantee, and consumers should be aware that the law as written would significantly restrict the market if it takes effect unchanged.
Can I still order hemp products from The Haze Connect?
