Is Delta-8 Legal in New Hampshire? What State Law Says in 2026

Status in New Hampshire as of September 2026

Restricted: 0.3% THC by weight cap

Partly. New Hampshire law does not authorise the sale of hemp-derived products containing more than 0.3% THC by dry weight, expressly including delta-8, so stronger products fall outside the hemp law. From 1 January 2027, SB 624 expressly prohibits such products and bans selling any hemp product containing THC to anyone under 21. No age limit applies before then.

What New Hampshire law says about delta-8 THC

New Hampshire regulates delta-8 through its hemp statute rather than a separate licensing scheme. Since 7 October 2023, RSA 439-A:4, added by HB 611, has said that nothing in the hemp chapter authorises the sale of hemp-derived products containing natural or synthetic THC above 0.3% on a dry-weight basis, in any formulation, including delta-8 THC.1 Low-strength products may therefore be sold as hemp, but products above that level have no legal footing as hemp. How the dry-weight test applies to edibles and drinks has not been set out in guidance.

SB 624, approved on 2 July 2026, tightens this from 1 January 2027. It adds the words such products are prohibited to RSA 439-A:4, names THCA, and changes the hemp definition to a total THC test.23 It also makes it unlawful for any person to sell or give away a hemp-derived product containing THC in any amount, including delta-8, to anyone under 21, and requires liquor licensees to comply with the hemp prohibition.4

New Hampshire has no adult-use cannabis market, so there is no licensed retail alternative for adults. Cannabis is available only to registered patients through the state’s therapeutic cannabis programme.

Pending changes to watch

SB 624 (2026, ch. 275) takes effect on 1 January 2027: total THC hemp definition, express prohibition of hemp products over 0.3% THC (naming delta-8 and THCA), and a 21+ rule for any hemp product containing THC.

How the federal hemp change affects New Hampshire

Separate from New Hampshire law, the federal definition of hemp is changing. Under the federal hemp redefinition passed in the FY2026 appropriations law, from 11 December 2026 hemp is measured by total THC, finished products are capped at 0.4 mg of total THC per container, and cannabinoids synthesised or manufactured outside the plant are excluded. Most delta-8 on the market is made by converting CBD, so most delta-8 products will fall outside the federal hemp definition from that date, whatever state law says.

A separate provision covering cannabinoids that the plant cannot produce naturally applies from 12 November 2026. Bills to delay or repeal the change are in congressional committees, but none had advanced as of September 2026. Our explainer on the federal hemp THC limit covers the detail.

Frequently asked questions

Is delta-8 legal in New Hampshire?

Only at low strength. State law does not authorise selling hemp-derived products with more than 0.3% THC by dry weight, and it names delta-8 expressly. From 1 January 2027 such products are prohibited outright, and hemp products containing any THC may not be sold to people under 21.

What is the age limit for delta-8 in New Hampshire?

There is no hemp-specific age limit until 31 December 2026. From 1 January 2027, SB 624 makes it unlawful for anyone to sell or give away a hemp-derived product containing any amount of THC, including delta-8, to a person under 21.

Can I buy delta-8 at a New Hampshire dispensary?

No. New Hampshire has not legalised adult-use cannabis. Its alternative treatment centres serve only registered therapeutic cannabis patients, and they are not a retail outlet for hemp-derived delta-8 products. Adults without a patient card have no licensed cannabis store to buy from in the state.
