Crosby Road Cannabis Guide: Dover, New Hampshire

Dover is the oldest permanent settlement in New Hampshire and now the anchor of a fast-growing Seacoast corridor, with the Cocheco River mills converted to apartments and offices and a commuter rail platform putting Boston within reach. Around 33,000 people live here, and the population skews younger than the state average thanks to spillover from the University of New Hampshire one town over in Durham.

The city holds one of the seven Alternative Treatment Centers in the state. Temescal Wellness operates at 26 Crosby Road, off the Sixth Street side of the city, and serves card holders from Rochester, Portsmouth, Somersworth, and everywhere else on the Seacoast, since a New Hampshire registry card works at any licensed center. Nothing is taxed at the counter, purchases are capped at two ounces in any ten-day window, and no operator in the state delivers.

What makes Dover different from the rest of New Hampshire is what sits across the Salmon Falls River. Eliot, South Berwick, and Berwick are Maine towns minutes away, and Maine's adult-use system sells to anyone 21 or older with a 14 percent cannabis sales tax and legal delivery inside its own borders. Bringing any of it back into Dover crosses a state line, which is a federal offense, and puts you under New Hampshire penalties the moment you are home. The retail that fields the confusion sits along Central Avenue downtown and the Route 108 plazas near Weeks Crossing.

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.
