TL;DR:
- Possession of up to three-quarters of an ounce is a civil violation in New Hampshire, not a criminal offense. Medical cannabis remains fully legal for registered patients, but home cultivation and retail sales for adults are prohibited. Pending legislation could expand access in 2026, but most bills are currently stalled or vetoed.
Recreational cannabis remains illegal in New Hampshire, but possession of up to 3/4 ounce (21 grams) is a civil violation under RSA 318-B:2-c, not a criminal offense. Medical cannabis is fully legal under RSA 126-X for registered patients. The single most important development to watch in 2026 is HB 1633, a comprehensive adult-use legalization bill that passed the House but faces a realistic veto from Governor Kelly Ayotte.
Here is what that means for you right now:
The sections below unpack each of these points in detail, including the medical program steps, pending bill timelines, and what to do if you are stopped or charged.
This article provides general legal information, not legal advice. Confirm current rules with the New Hampshire DHHS or a qualified attorney.
New Hampshire decriminalized possession of a small amount in 2017 through HB 640, codified at RSA 318-B:2-c. A first or second offense carries a $100 civil fine. Repeat violations escalate, and possession above the 0.75 oz threshold scales to misdemeanor or felony territory depending on the amount and circumstances.
What decriminalization does not do is legalize cannabis. Sale, distribution, and cultivation remain felony offenses under RSA 318-B:26, with sentence enhancements for activity near schools. A single plant can expose you to felony manufacturing charges because cultivation is classified as manufacturing under the statute.
Effective January 1, 2025, cannabis must be stored in your trunk or the least-accessible compartment of your vehicle. Violating this rule carries a $150 fine and potential driver’s license suspension. Passengers are not exempt from responsibility, and drivers under 21 face heightened consequences. Open-container enforcement is an outsized practical risk: a routine transport mistake can trigger administrative license consequences more disruptive than the civil possession fine itself.
Pro Tip: Keep any cannabis in a sealed bag in your trunk, not in a center console or glove compartment. The rule applies even to medical patients traveling with lawfully purchased product.
New Hampshire uses an impairment-based standard for cannabis DUI. There is no per-se THC blood limit; prosecutors must prove actual impairment through field sobriety tests, officer observations, and sometimes a Drug Recognition Expert evaluation. That standard cuts both ways: it gives defense attorneys room to challenge weak evidence, but it also means you can be charged even with a low THC reading if your driving behavior raises suspicion. For a detailed look at how NH handles impaired-driving stops, the first-offense DWI guide from Lydon Law covers penalties and what to expect at each stage.
Paraphernalia possession is a separate civil violation. Public consumption is prohibited statewide. Hemp-derived CBD products with less than 0.3% THC are federally legal and sold openly in New Hampshire; cannabis-derived products, regardless of THC concentration, remain subject to RSA 318-B restrictions unless purchased through the medical program.
Crossing state lines with cannabis purchased in a neighboring state is a federal offense and can expose you to felony charges regardless of the amount.
The Therapeutic Cannabis Program, established in 2013 under RSA 126-X, is the only legal pathway to purchase cannabis in New Hampshire today. DHHS administers the program, issues registry ID cards, and oversees the nonprofit Alternative Treatment Centers that serve as the sole retail source.
New Hampshire recognizes out-of-state medical cannabis cards. Visiting patients may purchase up to the state’s 2-ounce/10-day limit, but must present a valid out-of-state registry card and photo ID. Critically, not every ATC accepts out-of-state cards.
Pro Tip: Call the ATC before you visit. Policies on out-of-state patients vary by location, and making the trip without confirming can leave you without access.
A New Hampshire medical card provides state-level criminal immunity for therapeutic use. It does not protect you from federal prosecution, does not affect your Second Amendment rights under federal law any differently than cannabis use generally, and does not guarantee employment protections in federally regulated workplaces. Home cultivation remains prohibited for registered patients, the same as for everyone else.
Because ATCs operate as nonprofits under tightly regulated cultivation rules, patients often pay more for less variety than they would in neighboring states with open adult-use markets. That supply-and-cost gap is exactly what SB 468 aimed to address.
New Hampshire’s 2026 legislative session produced significant activity on cannabis, but most of it stalled before reaching the governor’s desk or was vetoed after passage.
HB 1633 is the most consequential bill in recent memory. It would create a regulated adult-use market for residents 21 and older, establish possession limits for flower, concentrates, and infused products, and set up a retail licensing and taxation framework. The House passed the bill, but New Hampshire senators rejected the House-passed legalization measure, effectively stalling it in 2026. Even if the Senate had advanced it, Governor Ayotte’s opposition made enactment unlikely without a veto override.
HB 75 addressed annulment and record-clearing provisions for prior cannabis convictions. Record relief efforts have been a recurring theme in recent sessions; past measures like HB 196 in 2024 passed the House but stalled in the Senate. HB 75 followed a similar path, reflecting the broader pattern of House support and Senate resistance.
SB 468 proposed allowing ATCs to expand cultivation through greenhouse operations, a direct response to the affordability and supply problems patients face. Supporters argued that loosening cultivation rules would lower prices and improve product access. Governor Ayotte vetoed the bill, citing concerns about the state’s readiness to expand the program.

| Category | Current Law | Proposed Under HB 1633 |
|---|---|---|
| Usable flower (adults) | 0.75 oz (21 g) civil threshold | Up to 2 oz for personal possession |
| Concentrates | Hashish included in decrim threshold | Approximately 10 g proposed |
| Infused products (edibles) | No separate civil threshold; treated as cannabis | Milligram THC limits proposed in drafts |
| Medical patients (flower) | 2 oz per 10-day period (RSA 126-X) | No change proposed |
| Home cultivation | Prohibited; felony exposure under RSA 318-B | Limited home grow proposed for adults |
Growing even a single plant is treated as manufacturing under RSA 318-B, which means felony charges are possible regardless of the quantity. That statutory classification is why home-grow proposals are politically sensitive: changing the law requires reclassifying an act that currently carries felony exposure. Until legislation passes and takes effect, any cultivation activity puts you at significant legal risk.
Retail adult-use purchases are not available today. The only legal point of sale remains the nonprofit ATC network, accessible only to registered patients and qualifying out-of-state visitors.
The difference between a civil possession violation and a criminal charge often turns on the amount, packaging, and presence of other items like scales or large amounts of cash. Prosecutors use those factors to argue intent to distribute, which escalates a possession matter to a felony. Understanding how NH criminal charges work from the start helps you avoid missteps that could complicate your defense.
Common defense angles in cannabis cases include unlawful search and seizure under the Fourth Amendment, chain-of-custody issues with evidence, and medical program defenses for registered patients. Arraignment typically occurs within 24–72 hours of arrest; having counsel before that hearing matters.
Pro Tip: If you are a medical patient who travels with purchased cannabis, keep your registry card and ATC receipt together in a separate document holder in your glove compartment, and store the product itself in the trunk. That separation makes it immediately clear to an officer that the product was lawfully obtained.
For readers facing drug possession charges in New Hampshire, the earlier you engage an attorney, the more options you have.
New Hampshire cannabis law in 2026 is a patchwork: decriminalization for small amounts, a functioning medical program, and major legalization bills that keep stalling before a governor willing to veto them.
| Point | Details |
|---|---|
| Decriminalization threshold | Possession of a small amount is a civil violation with a fine, not a criminal charge. |
| Medical program requirement | Patients need a DHHS registry card and are limited to 2 oz per 10-day purchase period under RSA 126-X. |
| Home cultivation is a felony | Growing any cannabis, even one plant, is classified as manufacturing under RSA 318-B and carries felony exposure. |
| Open-container penalty | Storing cannabis outside the trunk or least-accessible compartment carries a $150 fine and possible license suspension. |

Most people who ask about New Hampshire pot laws are really asking one question: “Am I safe?” Decriminalization has genuinely changed day-to-day enforcement. Officers are not arresting adults for a half-ounce in their pocket the way they once did. That shift is real and worth acknowledging.
What has not changed is the felony structure underneath. Sale, distribution, and cultivation carry serious criminal exposure, and those charges do not disappear because public opinion has shifted. The people I see facing the most serious consequences are not the ones who misread the possession limit by a few grams. They are the ones who assumed that because small possession is now civil, the broader legal environment had softened. It has not.
The open-container rule is a perfect example of a law that catches people off guard. A $150 fine sounds minor, but a license suspension can affect your job, your family, and your ability to meet court obligations. That administrative consequence can ripple further than the underlying cannabis charge.
My honest view: until legalization passes and takes effect, the safest posture for any New Hampshire resident is to treat cannabis the way the law actually treats it, not the way they wish it did. If you are a medical patient, know your limits and carry your documentation. If you are not a patient and you use cannabis, understand that the civil possession threshold is narrow and the felony line for cultivation or distribution is not.

Yes. New Hampshire’s dispensaries, called Alternative Treatment Centers, sell only to registered patients with a valid DHHS registry card or to qualifying out-of-state visitors presenting a valid out-of-state medical card and photo ID. There is no adult-use retail market in New Hampshire.
Infused products like gummies are legal only for registered medical patients who purchase them through a licensed ATC. Possessing edibles without a valid registry card falls under the same RSA 318-B restrictions as any other cannabis product.
Possession above the 0.75 oz (21 g) decriminalization threshold is no longer a civil matter. Depending on the amount and circumstances, it can be charged as a misdemeanor or felony under RSA 318-B, with significantly higher penalties than the $100 civil fine.
No. Home cultivation is prohibited for both recreational users and registered medical patients. Under RSA 318-B, growing even a single plant is classified as manufacturing, which carries felony exposure regardless of the quantity involved.
You can purchase from participating ATCs in New Hampshire using a valid out-of-state medical registry card and photo ID, up to the 2-ounce/10-day limit. Not every ATC accepts out-of-state cards, so calling ahead before visiting is strongly recommended.
