Is Hemp-Derived Delta-9 THC Legal in New Hampshire?

Last reviewed: May 21, 2026

No. Hemp-derived delta-9 edibles and beverages that exceed 0.3 percent delta-9 by dry weight in any formulation are not authorized for sale in New Hampshire. RSA 439-A:4, added by HB 611 (Chapter 237, Laws of 2023) and effective October 7, 2023, expressly excludes hemp products containing delta-9 THC above 0.3 percent in any formulation. Most hemp-derived delta-9 edibles fail that test on a per-formulation basis once the milligrams per gram of total product weight cross the 0.3 percent line, which is the practical effect for almost all commercial 10 mg gummies. There is no separate state mg cap because the statute does not authorize the underlying product.

New Hampshire Cannabis and Hemp Overview

New Hampshire operates the Therapeutic Cannabis Program under RSA 126-X, originally created by HB 573 in 2013. HB 1278 (2024), signed August 2, 2024 and effective October 1, 2024, expanded eligibility to any debilitating or terminal condition for patients 21 and older with a practitioner certification. The Department of Health and Human Services administers the program.

Adult-use cannabis is not legal. HB 1633 (2024) cleared both chambers in different forms and died in conference. HB 198 (2025) passed the House 208-125 in March 2025 and was tabled by the Senate in May 2025. Governor Kelly Ayotte has signaled she would veto legalization.

The hemp framework lives under RSA 439-A. HB 459 (2019) created the chapter. HB 611 (2023) added RSA 439-A:4, the section that restricts intoxicating hemp. The Department of Agriculture, Markets and Food administers hemp registration.

What New Hampshire Law Actually Says About Hemp-Derived Delta-9

RSA 439-A:1 defines hemp using the federal delta-9-only standard at 0.3 percent dry weight. RSA 439-A:4 then says the chapter cannot be construed to authorize the sale of products derived from hemp containing natural or synthetic THC greater than 0.3 percent on a dry weight basis in any formulation, naming delta-9 THC explicitly. The phrase "in any formulation" is what does the work for hemp delta-9 edibles, because a 10 mg gummy may technically be calculated as below 0.3 percent of the gummy mass, but the statute captures any formulation containing the named cannabinoid above the threshold.

RSA 318-B (Controlled Drug Act) continues to treat marijuana, including delta-9 THC outside the hemp framework, as a Schedule I controlled substance. RSA 318-B:2-c decriminalizes personal possession of three-quarters of an ounce or less of marijuana as a violation with a $100 fine, but that does not authorize commercial sale.

How Enforcement Has Played Out

Enforcement at hemp retail has been uneven. Some convenience stores, smoke shops, and beverage retailers continue to stock hemp delta-9 product. The Attorney General has joined multistate letters urging Congress to close the federal hemp loophole, which reinforces the state interpretation that intoxicating hemp products fall outside RSA 439-A. Enforcement has focused on sales to minors and packaging mimicry rather than systematic seizures.

What This Means for Retailers Selling Hemp Delta-9 in New Hampshire

• RSA 439-A:4 names delta-9 by statute and uses "in any formulation" language that captures gummies, beverages, and chocolates.
• Discontinue hemp-derived delta-9 SKUs to align with the express statutory text.
• Maintain certificates of analysis if you continue to stock product, but understand the statutory bar applies regardless of finished-product mg calculations.
• Verify ID at point of sale. Sales to minors have been the most consistent enforcement trigger.
• Track federal H.R. 5371 §781 effective November 12, 2026. The new total-THC test and 0.4 mg per container cap remove federal Farm Bill cover from the rest of the existing category nationwide.

What This Means for Consumers Buying Hemp Delta-9 in New Hampshire

Hemp-derived delta-9 edibles and beverages are not authorized for retail sale under RSA 439-A:4. Some stores carry them anyway. Out-of-state online retailers ship to New Hampshire addresses under federal Farm Bill cover. Hemp-derived delta-9 produces the same effects as marijuana-derived delta-9 and triggers standard urine drug tests.

Pending Federal Change

The biggest near-term shift for hemp-derived delta-9 is federal. H.R. 5371 §781, signed November 12, 2025, replaces the 2018 Farm Bill delta-9-only standard with a post-decarboxylation total-THC test and caps finished hemp products at 0.4 mg total THC per container. The provision takes effect November 12, 2026. Industry counsel estimates that the vast majority of current hemp-derived delta-9 edibles and beverages will be non-compliant on that date. New Hampshire already restricts the category under RSA 439-A:4, so the federal change reinforces the practical reality.
