Merrimack Village District Cannabis Guide: Merrimack, New Hampshire

Merrimack sits on the river of the same name between the state's two largest cities, a town of roughly 26,000 built around the Everett Turnpike exits, the Anheuser-Busch brewery with its Clydesdale stables, and a large Fidelity Investments campus that anchors white-collar employment along Continental Boulevard.

Its cannabis significance is out of proportion to its size. GraniteLeaf Cannabis, the operator formerly known as Prime ATC, runs one of the seven state dispensaries at 380 Daniel Webster Highway, Units A and C. Manchester and Nashua together hold more than 200,000 people and neither has a licensed counter, so this storefront absorbs the patient traffic from both, along with Bedford, Amherst, Hollis, and Litchfield. Two ounces per ten-day period is the cap, and no tax is charged, because New Hampshire levies none.

The commercial spine here is Daniel Webster Highway itself, which runs the length of the town from the Bedford line to the Nashua line past plazas, service businesses, and the retail that fills the space between the turnpike exits. Merrimack Premium Outlets at the southern end pulls shoppers from three states, and the surrounding businesses field the same cannabis question daily from visitors who assume the outlets and a dispensary must be connected. They are not, and anything on a local shelf claiming a hemp-derived high sits outside what RSA 439-A:4 authorizes.

New Hampshire is surrounded on three sides by legal adult-use markets and has none of its own. The only legal cannabis counter in the state is the Therapeutic Cannabis Program, created by RSA 126-X in 2013, with the first dispensary sales in 2016. Seven Alternative Treatment Centers, which state law requires to be not-for-profit entities, cover the whole state: two run by GraniteLeaf Cannabis in Merrimack and Chichester, two by Sanctuary in Plymouth and Conway, and three by Temescal Wellness in Dover, Keene, and Lebanon.

Getting in is easier than it used to be. Since a 2024 law, any adult 21 or older with a debilitating or terminal condition or symptom can be certified if the provider puts the condition in writing and attests that the benefits likely outweigh the risks. Dentists, podiatrists, optometrists, naturopaths, and providers licensed in Maine, Massachusetts, or Vermont can all certify. You mail the application and a $50 check to the program office at 29 Hazen Drive in Concord. Card holders can hold two ounces and cannot obtain more than two ounces in any ten-day period. Nothing at the register is taxed, because the state has no sales tax at all.

For everyone else, possession is decriminalized rather than legal. Three-quarters of an ounce or less, or five grams of hash, is a $100 violation for a first or second offense. An adult 21 or older carrying up to 300 milligrams of edibles bought legally in another state, still in its original child-resistant packaging, gets the same civil treatment. Selling any amount is still a felony, and unsealed cannabis has to ride in the trunk.

The 2026 session ended the way the last several did. The House passed a legalize-and-regulate bill, HB 186, 208-135 in January; the Senate tabled it. The one thing that did become law was SB 468, which lets the dispensaries grow in greenhouses instead of under lights - the legislature overrode Governor Kelly Ayotte's veto in August 2026.

Three operators hold every New Hampshire dispensary license, and each sells its own house line rather than a multi-brand shelf. GraniteLeaf Cannabis, formerly Prime ATC, runs Merrimack and Chichester. Sanctuary runs Plymouth and Conway. Temescal Wellness runs Dover, Keene, and Lebanon, and posts patient affordability discounts for veterans and for patients on SSDI, SSI, or Medicaid. There is no verified national brand shelf here and no legal hemp-THC brand to recommend, because RSA 439-A:4 does not authorize hemp products over the 0.3 percent dry-weight THC line.

Three things define the 2026 picture. The House passed HB 186 to legalize and regulate sales 208-135 in January, and the Senate tabled it, repeating the 2025 outcome for HB 198. CACR 19, which would have sent the question to voters without needing the governor's signature, never got a House vote. Then in August the legislature overrode Governor Ayotte's veto of SB 468 by 16-8 in the Senate and 257-44 in the House, allowing greenhouse cultivation intended to lower patient costs. Every seat in both chambers and the governor's office is on the November 3, 2026 ballot.
