The Federal Hemp Cliff — November 12, 2026 (PL 119-37 § 781)

Last verified: May 2026

What PL 119-37 § 781 Does

PL 119-37 § 781 is the hemp-regulation provision in the 2026 federal appropriations / Farm Bill compromise package signed into law in late 2025. The substantive changes — effective November 12, 2026, with limited transitional grace for product manufactured before that date — are:

1. Total-THC redefinition. "Hemp" is redefined using a total THC threshold on a dry-weight basis. Total THC is computed as: delta-9 THC + (THCA × 0.877). Under this calculation, THCA flower with 0.2% delta-9 / 25% THCA tests at approximately 22% total THC and falls outside the federal hemp definition. THCA flower as currently retailed in SC will be federally Schedule I.
2. 0.4 mg per package cap on consumer products. Consumable hemp products may contain no more than 0.4 mg of total THC per consumer package. A 5-mg-per-serving gummy is 12.5× over the cap. A 10-mg-per-can seltzer is 25× over. Effectively all current intoxicating consumer hemp products are noncompliant.
3. Synthetic / non-naturally-occurring cannabinoid ban. Cannabinoids that are synthesized or produced through chemical conversion are banned outright. This sweeps in delta-8 THC (synthesized from CBD via acidic conversion), HHC (hydrogenated CBD), THC-O (acetylated THC), and most novel cannabinoids that have populated the 2022-26 market.

Why the Federal Cliff Matters for SC Specifically

Three SC-specific dynamics converge at the federal cliff:

• The Cook-Wilson conflict becomes substantially moot. Solicitor General Cook’s September 16, 2024 opinion that hemp-derived delta-9 beverages compliant with the 2018 Farm Bill are legal rests on a federal definition that no longer exists after November 12, 2026. AG Wilson’s position prevails by federal preemption regardless of SG Cook’s opinion. See Wilson-Cook conflict page.
• The 2025-26 SC hemp bills become marginal. H.3924 (Wooten, regulate-not-ban) and H.4758 (Newton, total ban) both become layered on top of a federal framework that has already substantially restricted the products at issue. See 2025-26 hemp bills page.
• The Operation Ganjapreneur prosecutions accelerate. AG Wilson’s prosecutions for trafficking marijuana 10-100 lbs become substantially easier to win once the federal definition no longer protects products with measurable THC. See Operation Ganjapreneur page.

What Remains Federally Lawful After November 12, 2026

After the cliff, lawful hemp consumer products in the U.S. will be limited to:

• Non-intoxicating CBD products (cannabidiol, cannabigerol) with total THC at or below 0.4 mg per package — essentially the pre-2018 / industrial-hemp market.
• Hemp fiber, grain, and industrial uses — rope, textiles, food protein.
• FDA-approved cannabinoid pharmaceuticals — e.g., Epidiolex (cannabidiol).

Lawful retail will not include: delta-8 THC anything, HHC, THC-O, THCA flower, 5-10 mg delta-9 seltzers or gummies, vape cartridges with measurable THC, or any product marketed for psychoactive effect.

What SC Retailers Should Expect

• Smoke shops and gas stations — Will lose the bulk of their THC-product inventory. CBD-only products and traditional smoke-shop merchandise (pipes, accessories) will remain.
• Liquor stores — Will lose 5-10 mg delta-9 seltzers. The Senate-amended H.3924 from March 2026 attempted to corral seltzers into liquor stores, but federal preemption ends the channel regardless.
• Specialty hemp dispensaries — The 90+ dedicated hemp stores in the Post and Courier 2024 survey face existential pressure. Most will close, pivot to CBD-only, or operate in defiance of federal law (with federal-prosecution exposure).
• Restaurants and bars carrying THC seltzers — Channel ends.
• Online direct-to-consumer hemp brands shipping into SC — Federal-mail prohibition risks substantially increase.

What SC Consumers Should Expect

• The retail wave is ending. Consumers who currently purchase delta-8 carts or 10-mg seltzers locally should not expect to do so after November 12, 2026.
• Cross-border medical and adult-use jurisdictions are unaffected by the federal hemp cliff. Cherokee NC (EBCI Great Smoky Cannabis Co., 21+ adult-use) and Maryland (adult-use, ~7 hours from Charleston) remain available, though product brought into SC remains exposed to § 44-53-370 penalties. See Cherokee EBCI page.
• Federal Schedule III rescheduling may interact: the April 28, 2026 DOJ Schedule III rescheduling order, combined with the federal hemp cliff, may eventually force broader cannabis-policy realignment. See federal rescheduling mirror page.

What SC’s Hemp Crop Industry Should Expect

The SC Hemp Farming Act of 2017 / 2019 framework, codified at S.C. Code Title 46, Chapter 55, regulates hemp cultivation — a separate question from consumer-product retail. Crop hemp at SC's already-modest 2024 scale (98 farmers, 40 outdoor acres, 62,600 sq ft indoor, 10 acres harvested) shifts further toward fiber, grain, and CBD-only floral hemp markets. The cannabinoid-extraction floral-hemp boom of 2019-21 — which had already collapsed by 2024 — ends formally on November 12, 2026. See Hemp Farming Act page.

What SC’s 2025-26 Hemp Bills Will Mean

If the General Assembly enacts H.3924 (regulate-not-ban) by May 8, 2026 sine die: SC adds state-level age 21, packaging, retail license, and dosing caps to a consumer-product channel that federal law has already substantially restricted. The state framework operates only over the narrow remaining window of compliant CBD-only products plus any state-permitted carve-outs.

If the General Assembly enacts H.4758 / H.4759 (total ban): SC moves into closer alignment with the new federal framework, perhaps slightly stricter, with state-law trafficking exposure layered on top of federal Schedule I treatment for non-compliant products.

If the General Assembly enacts nothing (the most likely outcome): the federal cliff takes effect with no state framework in place. AG Wilson continues Operation Ganjapreneur prosecutions; SC retailers face federal exposure independently of state law.

What Comes After the Cliff

The November 12, 2026 cliff resets the SC hemp-policy debate. The medical-cannabis question (Sen. Davis’s Compassionate Care Act, S.53) is unaffected by the federal hemp cliff. The 2027 SC General Assembly will inherit: a substantially smaller consumer-hemp market; a new gubernatorial administration (the 2026 SC governor’s race is open); the April 28, 2026 federal Schedule III rescheduling for marijuana (which may, under S.C. Code § 44-53-160(c), force corresponding state action); and unresolved questions about how much of the regulate-not-ban policy framework is salvageable. See McMaster + 2026 race page.
