Cannabis Regulations in Nashua, NH: What Residents Actually Need to Know

Every city handles cannabis regulations a little differently. In Nashua, New Hampshire, there are 2 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Home Cultivation

Home cultivation of cannabis — recreational or medical — is prohibited statewide in New Hampshire. New Hampshire is the only state in New England that has not legalized adult-use cannabis: HB 1633 (2024), the most recent legalization vehicle, was killed by the House on June 13, 2024 after a failed Senate compromise. Possession of three-quarters of an ounce or less by an adult is a civil violation under RSA 318-B:2-c (a $100 fine for a first or second offense, $300 for a third within three years, and a class B misdemeanor for a fourth within three years), but cultivation of any amount remains a criminal offense under RSA 318-B:2. The therapeutic cannabis program under RSA 126-X allows qualifying patients to purchase product from an Alternative Treatment Center (ATC), but does NOT authorize patient home grow — cultivation is the exclusive function of state-licensed ATCs.

Key details: Home Cultivation: Prohibited statewide — felony under RSA 318-B:26. Medical Home Grow: Not authorized — RSA 126-X is dispensary-only. Possession ≤3/4 oz (adult): Civil violation — $100 fine (RSA 318-B:2-c). Possession >3/4 oz: Class A misdemeanor — RSA 318-B:26. Cultivation (any amount): Felony — RSA 318-B:2 / RSA 318-B:26.

Growing any cannabis plant in Nashua is treated as manufacture of a controlled drug under RSA 318-B:2 and is a felony under RSA 318-B:26 — up to 7 years for less than one ounce of finished product or 3 ounces of plant material, longer for larger amounts and for repeat offenders. Plants are subject to seizure. Possession of more than three-quarters of an ounce of cannabis remains a class A misdemeanor under RSA 318-B:26, punishable by up to one year and a $350 fine ($1,200 for repeat offenders). Possession of three-quarters of an ounce or less is a civil violation under RSA 318-B:2-c with a $100 fine (third offense $300, fourth offense within three years becomes a class B misdemeanor). Therapeutic cannabis patients who cultivate at home lose the RSA 126-X protections and are charged under RSA 318-B:26 like any other person. There is no city-level decriminalization in Nashua beyond what RSA 318-B:2-c provides statewide.

This is one of the stricter rules in Nashua's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Dispensary Zoning

Nashua has no recreational cannabis dispensaries because New Hampshire has no recreational cannabis market — HB 1633 (2024), the most recent adult-use legalization vehicle, was killed in the House on June 13, 2024. The only legally operating cannabis retailers in New Hampshire are therapeutic-cannabis Alternative Treatment Centers (ATCs) licensed by the Department of Health and Human Services under RSA 126-X:7. As of 2026, the seven operating ATC dispensary locations are Sanctuary ATC (Plymouth and Conway), Temescal Wellness (Keene, Lebanon, and Dover), and GraniteLeaf Cannabis (Merrimack and Chichester); none of those sites are in Nashua. ATC siting in any New Hampshire municipality is governed by local zoning, and Nashua's Chapter 190 (Land Use Code) has not designated specific zones for ATCs.

Key details: Nashua ATC Status: No operating ATC dispensary in Nashua. NH Adult-Use Status: No legal market — HB 1633 killed by House 178-173 on June 13, 2024. Therapeutic Authority: RSA 126-X:7 — DHHS-licensed ATCs only. Operating NH ATCs (2026): Sanctuary (Plymouth, Conway), Temescal (Keene, Lebanon, Dover), GraniteLeaf (Merrimack, Chichester). Local Zoning Required: ATC must obtain Nashua zoning approval before DHHS final registration.

Operating any cannabis dispensary in Nashua without DHHS registration as an ATC under RSA 126-X:7 violates the New Hampshire Controlled Drug Act, RSA 318-B, and is enforceable as a felony under RSA 318-B:26 (manufacture, sale, or distribution of a controlled drug). Local enforcement is also available under Chapter 190 (cease-and-desist for unauthorized land use) and the Nashua business-licensing provisions. Operating in violation of an ATC's RSA 126-X registration conditions (e.g., outside an approved location, with more product than permitted, or to non-registered customers) can result in registration suspension or revocation by DHHS in addition to RSA 318-B criminal charges. There is no city authority to license a recreational dispensary — none exists under state law.

This is not one of those rules that cities tend to ignore. Nashua actively enforces its dispensary zoning requirements.

The Bottom Line

Nashua is tougher than many cities when it comes to cannabis regulations. Out of the 2 rules covered here, 2 are rated strict. If you are a homeowner, renter, or business owner in Nashua, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.
