NH Hemp’s November 2026 Federal Cliff

Last verified: April 2026

What P.L. 119-37 Changes

The 2018 Farm Bill defined legal hemp as cannabis containing not more than 0.3% delta-9 THC by dry weight. Because the rule measured only delta-9, the door opened to chemically converted hemp cannabinoids: Delta-8, Delta-10, THC-O, HHC, hemp-derived Delta-9 edibles (low concentration but high total dose), and high-THCA flower (which converts to delta-9 when heated).

Section 781 of P.L. 119-37 closes the loophole at the federal level by changing three things at once:

• Measurement standard — from delta-9 only to total THC including THCA. THCA flower that tests under 0.3% delta-9 today often tests at 15–25% total THC and would no longer qualify as federal hemp.
• Ceiling unit — from a percentage by dry weight to 0.4 mg total THC per finished consumer container. A typical 100-mg gummy package containing 10 mg per serving is two orders of magnitude over the new cap.
• Synthetic exclusion — synthetically converted cannabinoids (Delta-8 from CBD, THC-O, HHC) are excluded from the hemp definition entirely, regardless of source plant.

Effective date: November 12, 2026. One year from signing — built in to give Congress room to amend before products federally re-classify as Schedule I marijuana.

Section 781 of the Continuing Appropriations Act of 2026 (P.L. 119-37) was inserted by Sen. Mitch McConnell (R-KY) and signed by President Trump on November 12, 2025. It redefines hemp using "total THC" including THCA, sets a 0.4 mg total THC ceiling per finished consumer container, and excludes synthetically converted cannabinoids. Effective November 12, 2026.

What Becomes Federally Illegal

Industry analyses estimate roughly 95% of currently legal U.S. intoxicating hemp products will become Schedule I marijuana federally on the effective date. The categories most affected:

• Delta-8 and Delta-10 THC products — almost all are synthetically converted from CBD; excluded.
• HHC and HHC-O — synthetically converted; excluded.
• THC-O acetate — synthetically converted; excluded.
• Hemp-derived Delta-9 edibles — products marketed as “under 0.3% delta-9 by dry weight” that contain 5–100 mg active THC per package. The 0.4 mg per-container cap eliminates these.
• THCA flower — raw cannabis flower under 0.3% delta-9 by dry weight but high in THCA. Total-THC measurement reclassifies most of it as marijuana.

Products likely to remain federal hemp: low-dose CBD oils and tinctures with negligible THC, finished cosmetics, hemp seed and fiber, and some hemp-foods products.

NH-Specific Implications

New Hampshire’s gas-station and CBD-shop gray market is concentrated in Manchester, Nashua, Concord, Portsmouth, Dover, Keene, and the southern tier. NH has not enacted state-level intoxicating-hemp restriction comparable to Iowa’s HF 2605 or Tennessee’s HB 1376 (a 2024 attempt — SB 505 — passed the Senate unanimously but did not become law in its initial form). What NH does in 2026–2027 will determine whether the gray market collapses entirely on the federal effective date or transitions to a lower-THC retail product mix.

Three concrete NH effects on November 12, 2026:

• Gas stations and vape shops selling Delta-8, hemp Delta-9 edibles, HHC, and THCA flower face product reformulation or market exit. Most NH retailers carry brands sourced through national distributors, so federal supply chains will dictate outcomes.
• The personal-use 300mg edibles carve-out under RSA 318-B:2-c remains a state-law civil violation framework, but federally any product over 0.4 mg total THC becomes Schedule I — meaning the carve-out covers products that are federally illegal. Adults 21+ traveling back from Massachusetts or Maine with edibles continue to face the federal interstate-trafficking exposure under 21 U.S.C. §841 regardless.
• TCP products dispensed by NH’s Alternative Treatment Centers under RSA 126-X are unaffected. The therapeutic cannabis program operates as a state-controlled medical system distinct from the hemp framework.

Counter-Bills and Pending Action

Several federal vehicles aim to reverse or delay the cliff:

• HEMP Act — would reverse the 0.4 mg cap and restore the 2018 Farm Bill’s delta-9-only measurement.
• Hemp Planting Predictability Act (H.R. 7010) — proposes a 2-year delay of the November 12, 2026 effective date.
• Trump’s December 2025 rescheduling EO encouraged Congress to revisit hemp THC limits but did not block the November 12 effective date.

None has passed as of April 2026. Industry stakeholders — the Hemp Industries Association, the U.S. Hemp Roundtable, and state-level hemp coalitions — are lobbying for delay or repeal. NORML is opposed to the ban-by-redefinition approach.

What NH Could Do

Three state-level paths:

• Pass adult-use legalization (HB 186 or successor) — would create a legal in-state retail framework that absorbs the demographics currently buying hemp-derivative products. Politically blocked by the Senate.
• Pass an HDC framework — A new chapter, RSA 179-A, has been proposed in 2026 to license and regulate hemp-derived cannabinoid (HDC) products through the NH Liquor Commission, including age restrictions (21+), tax structure, and licensing of HDC retailers, wholesalers, and manufacturers. As of April 2026, this framework has not been enacted; status remains in flux.
• Do nothing — allow the federal cliff to wipe out the in-state intoxicating-hemp market on November 12, 2026, with whatever lower-THC products remain federally legal continuing in the existing retail channels.

Compare to Iowa, Tennessee, Indiana

Iowa enacted HF 2605 (effective July 2024) restricting THC content in hemp products. Tennessee enacted HB 1376 (2025) with similar effect. Indiana, after years of permissive treatment, has moved toward restriction. NH has not enacted a comparable state law. Its 2024 SB 505 attempted a permanent ban on hemp-derived intoxicating products; it passed the Senate unanimously but did not become law in its initial form. The 2026 federal cliff may render state-level action moot in practice, but state-level rules continue to determine enforcement and retail channels.
