Portsmouth, New Hampshire Cannabis Guide: Legal Status, Where to Buy & Neighborhoods
A tourism city with no dispensary, ten minutes from Dover's licensed counter and a bridge span from Kittery's. The rules change mid-river.
Quick answer · Portsmouth, New Hampshire
Portsmouth has no dispensary. The nearest New Hampshire counter is Temescal Wellness in Dover, about eleven miles northwest, and it serves registered patients only. Kittery, Maine sells to any adult 21 or older across the Piscataqua, but bringing a purchase back over the bridge is a federal offense with New Hampshire penalties waiting.
Portsmouth Market Overview
Portsmouth packs a working port, a colonial downtown, and one of New England's better restaurant scenes into about 22,000 residents, then triples its daytime population with tourists and commuters from Pease International Tradeport. Market Square is the center of it, and Strawbery Banke and Prescott Park keep the waterfront busy from May through October.
The city has no cannabis retail. New Hampshire licensed seven Alternative Treatment Centers and the Seacoast's went to Dover, where Temescal Wellness operates on Crosby Road, roughly eleven miles and twenty minutes northwest via the Spaulding Turnpike. That counter serves registered patients only, applies the two-ounce ten-day purchase cap, and adds no tax, since New Hampshire levies none.
What makes Portsmouth unusual is the bridge. Kittery, Maine begins on the far side of the Piscataqua, and Maine sells adult-use cannabis to anyone 21 or older, with retail clustered near the Route 1 outlet corridor and Wallingford Square and a 14 percent cannabis sales tax at the register. Cross back over the Memorial Bridge with that purchase and you have committed a federal offense, and New Hampshire's possession rules apply the moment you land. Locally, the corridors fielding the questions are Lafayette Road along Route 1 south, Islington Street heading west out of downtown, and the Market Square blocks themselves, where visitors ask daily and no business on those streets can lawfully answer with a sale.
Delivery in Portsmouth
No cannabis delivery reaches Portsmouth lawfully from either side of the river. New Hampshire licenses no delivery at all, and its dispensaries may transfer product only in person to registered patients, designated caregivers, other centers, and visiting patients holding valid out-of-state cards. Maine does allow delivery within its own borders, and those licenses stop dead at the Piscataqua - a driver crossing into New Hampshire with product is committing a federal offense regardless of what Maine law permits. For a Portsmouth card holder the options are a drive to Dover or a registered caregiver making the trip on your behalf.
Popular Products in Portsmouth
- Flower
Card holders buy flower grown by the operator at the Dover counter twenty minutes away, untaxed. There is no legal flower sold anywhere in Portsmouth itself.
- Vapes
Cartridges and disposables are stocked in Dover for patients. The hemp-derived vapes sold in downtown and Lafayette Road shops are unregulated and not authorized above the 0.3 percent THC dry weight cutoff under state law.
- Pre Rolls
Available at the Dover store in singles and packs, and the simplest purchase for a patient making the round trip up the turnpike after work.
- Edibles
Patients buy them in Dover. Visitors should know the specific rule that applies here: an adult 21 or older holding 300 milligrams or less of THC in edible form bought legally in Maine, unopened in original packaging, faces a civil violation instead of a criminal charge.
- Concentrates
Live resin, rosin, and wax are on the Dover menu for card holders. For anyone else, hashish under five grams is a civil violation and a $100 fine in New Hampshire.
Top Brands in Portsmouth
For a Portsmouth patient the practical operator is Temescal Wellness, whose Dover store is the closest licensed counter and which posts affordability discounts for veterans and for patients receiving SSDI, SSI, or Medicaid - relevant in a city with heavy shipyard and Air National Guard employment. GraniteLeaf Cannabis and Sanctuary honor the same New Hampshire card further inland. Nothing on the hemp shelf in this city carries state authorization above 0.3 percent THC on a dry weight basis, so there is no local hemp brand worth recommending.
Pricing in Portsmouth
Dover counter prices run about $35 to $60 for an eighth and $40 to $70 for a cartridge with no tax added. Kittery shelf prices sit in a competitive Maine market but collect 14 percent cannabis sales tax at the register, and the return trip is the part that carries real risk rather than real cost. Factor twenty minutes each way to Dover, which is still the only lawful purchase available to a Portsmouth resident.
2026 Trends in Portsmouth
Portsmouth is the clearest illustration in New Hampshire of what the 2026 legislative outcome means: the House passed HB 186 in January, the Senate tabled it, and the border stays exactly where it is. The Seacoast delegation has generally backed legalization, and the tourism economy is the argument advocates use. For a Market Square or Lafayette Road business, being findable in local cannabis searches keeps summer visitors from defaulting to Kittery listings before they ask you anything.
Portsmouth FAQ
Is there a dispensary in Portsmouth?
No. The nearest is Temescal Wellness at 26 Crosby Road in Dover, about eleven miles northwest, and it serves registered therapeutic patients only.
Can I buy in Kittery and walk back?
Buying in Maine at 21-plus is legal there. Crossing the bridge back into New Hampshire with it is a federal offense, and state penalties apply once you are here.
Will a Maine delivery service come to Portsmouth?
No lawful one will. Maine delivery licenses cover Maine addresses only, and no permitted service crosses the Piscataqua.
What about tourists with out-of-state medical cards?
New Hampshire accepts visiting qualifying patients whose cards come from another state or from Canada. The Dover store sets its own verification process, so call before driving.
Can I consume at Prescott Park or on the waterfront?
No. Public parks and public places are excluded from the therapeutic program's protections statewide.
Does the naval shipyard change anything?
Yes. It is a federal installation, and cannabis is federally illegal, so no state card offers any protection on that property.
What do downtown shops actually sell?
CBD, hardware, and hemp products. RSA 439-A:4 authorizes no hemp-derived items over the 0.3 percent dry-weight THC line, so those are unregulated.
How do I get a New Hampshire card from the Seacoast?
Have a qualified provider complete a written certification, then send it, plus the $50 fee by check, to the Therapeutic Cannabis Program office on Hazen Drive in Concord.

Cannabis Prices in Portsmouth
New Hampshire pricing applies in Portsmouth. Expect local variation based on competition and area type:
Prices are set by three nonprofits with no competing retail, so they move slowly. Eighths generally run $35-$60, ounces land in the $250-$400 range, cartridges usually fall between $40-$70, and edible packs sit around $18-$30. Nothing is taxed at the counter, which quietly closes part of the gap with Massachusetts at 17-20% total tax and Maine at 14%. The greenhouse law passed in August 2026 is aimed squarely at production cost, so watch flower prices first.
