Is Delta-8 THC Legal in New Hampshire?

Last reviewed: May 21, 2026

No. Delta-8 THC is 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 states that the hemp chapter does not 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-8 THC, delta-9 THC, and any other THC isomer variant. Attorney General John Formella has joined multistate efforts urging Congress to close the federal intoxicating hemp loophole. There is no adult-use cannabis program in New Hampshire.

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 through Alternative Treatment Centers.

Adult-use cannabis remains illegal. HB 1633 (2024) cleared the House 239-141 in April 2024 and passed the Senate in amended form in May 2024, then died in conference when the House refused to concur. HB 198 (2025), an adult-use possession bill, 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 using the federal delta-9-only definition. HB 611 (2023) added RSA 439-A:4, the section that closes the intoxicating hemp loophole. The Department of Agriculture, Markets and Food administers hemp registration.

What New Hampshire Law Actually Says About Delta-8

RSA 439-A:4 is unusually direct. The chapter cannot be construed to authorize the sale of products derived from hemp that contain natural or synthetic THC greater than 0.3 percent on a dry weight basis, which appear in any formulation, including delta-8 THC, delta-9 THC, or any other THC isomer variant. The statute names delta-8 by name. Most commercial delta-8 is produced through acid-catalyzed conversion from hemp-derived CBD, which makes the synthetic-conversion question moot at the state level because the statute captures both natural and synthetic THC.

RSA 318-B (Controlled Drug Act) treats delta-8 THC as a Schedule I controlled substance to the extent it falls outside the hemp definition. RSA 318-B:2-c decriminalizes possession of three-quarters of an ounce or less of marijuana as a violation with a $100 fine, but that applies to personal possession of plant material rather than commercial sale of intoxicating hemp products.

How Enforcement Has Played Out

Enforcement has been uneven. The state has not run systematic delta-8 seizure operations against retailers. Some convenience stores and vape shops continue to stock delta-8 product. Attorney General Formella has been vocal in 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 priorities have skewed toward stores selling to minors and packaging that mimics mainstream candy brands.

What This Means for Retailers Selling Delta-8 in New Hampshire

• RSA 439-A:4 names delta-8 by statute. There is no statutory carveout.
• Discontinue or remove delta-8 SKUs to align with the express statutory text and avoid Controlled Drug Act exposure.
• If you continue to stock product, expect that finished-product testing will show THC above 0.3 percent and that the statute captures the SKU regardless of the source process.
• Verify ID at point of sale. Sales to minors have been the most consistent enforcement priority.
• Track federal H.R. 5371 §781 effective November 12, 2026. The federal change excludes synthetic and chemically converted cannabinoids and removes any federal Farm Bill cover for delta-8.

What This Means for Consumers Buying Delta-8 in New Hampshire

Delta-8 is not authorized for retail sale under RSA 439-A:4. Some stores stock it anyway. Out-of-state online retailers ship to New Hampshire addresses under federal Farm Bill cover. Delta-8 produces effects similar to delta-9 THC and shows up on standard urine drug tests as delta-9 metabolites because of structural similarity.

Pending Federal Change

The biggest near-term shift for delta-8 is federal. H.R. 5371 §781, signed November 12, 2025, explicitly excludes synthetic and chemically converted cannabinoids from the federal hemp definition. The provision takes effect November 12, 2026. After that date, delta-8 loses any remaining federal Farm Bill protection. New Hampshire already restricts the product under RSA 439-A:4, so the federal change tightens the practical reality nationwide rather than altering state law.
