The short answer is: partially. Recreational cannabis is still illegal, but possessing up to ¾ of an ounce has been decriminalized since 2017. Medical cannabis has been legal since 2013 through the state’s Therapeutic Cannabis Program. New Hampshire continues to debate reform while maintaining separate rules for recreational use, medical cannabis, and hemp-derived products.
Key Takeaways
- Recreational cannabis is illegal, but possession of up to ¾ ounce (21 g) has been decriminalized for most first and second offenses.
- Medical cannabis is legal through the Therapeutic Cannabis Program and registered patients can purchase cannabis from licensed Alternative Treatment Centers.
- Legalization efforts continue, but New Hampshire remains the only New England state without a legal recreational cannabis market.
Historical Overview of Cannabis Regulation in New Hampshire
New Hampshire has taken a more cautious approach to cannabis reform than its neighboring New England states. Medical cannabis became legal in 2013 when Governor Maggie Hassan signed House Bill 573 into law, creating the state’s Therapeutic Cannabis Program for patients with qualifying medical conditions. Initially, the program was among the most restrictive in the country, as patients were not allowed to cultivate cannabis at home and could only access products through licensed Alternative Treatment Centers.
In 2014, the state’s House of Representatives gave preliminary approval to a legalization bill that was modeled after Colorado’s adult-use system. While this bill didn’t become law, it paved the way for the significant policy change that followed. In 2017, House Bill 640 decriminalized possession of up to ¾ of an ounce of cannabis, replacing criminal penalties for most first-time offenses with civil fines.
Since then, lawmakers have introduced multiple legalization proposals, but disagreements in the Senate over how a legal market should operate have repeatedly stalled reform.
Hemp has also become part of the state’s cannabis landscape following the federal legalization under the 2018 Farm Bill and New Hampshire permits the cultivation and sale of hemp and hemp-derived products that comply with federal and state THC limits, supporting a growing market for products such as CBD.
Medical Cannabis in New Hampshire: Legal Provisions and Accessibility
Medical cannabis has been legal since 2013 through the state’s Therapeutic Cannabis Program that allows qualified patients to buy, possess, and use cannabis for therapeutic purposes, as long as they comply with state requirements. The program was expanded in 2024 to allow any debilitating medical condition to qualify and broaden which healthcare professionals can certify patients.
To qualify, a person must:
- Be a resident of New Hampshire
- Receive a written certification from an authorized healthcare provider
- Obtain a state-issued registry identification card
Regulations limit patients to obtaining up to two ounces of usable cannabis during any 10 days and dispensaries are required to monitor purchases to ensure compliance. Home cultivation is not currently permitted, despite several legislative proposals seeking to legalize it.
Current Legal Status of Recreational Marijuana in New Hampshire
Recreational cannabis is illegal in New Hampshire. However, the state decriminalized possession of small amounts in 2017.
Under current law, adults found in possession of up to ¾ of an ounce of cannabis or up to five grams of hashish generally face a civil violation instead of a criminal misdemeanor. A first or second offense is punishable by a $100 fine, while a third offense carries a $300 fine. A fourth offense within three years may result in misdemeanor charges.
When it comes to cannabinoid products, rules vary depending on their source:
- Marijuana-derived THC products are generally illegal outside the state’s medical cannabis program
- Hemp-derived products are permitted if they comply with state and federal law (cannabis containing no more than 0.3% delta-9 THC on a dry-weight basis)
- CBD extracted from compliant hemp is legal to buy and sell, provided it meets applicable hemp regulations
Possession, Cultivation, and Consumption: What’s Allowed in New Hampshire?
New Hampshire applies different rules to recreational and medical cannabis:
| Activity | Recreational Cannabis | Medical Cannabis |
| Possession | Up to ¾ oz (21 g) is a civil violation subject to a fine; larger amounts may result in criminal charges. | Registered patients may possess cannabis purchased through the Therapeutic Cannabis Program, subject to state limits. |
| Purchase | Not permitted in New Hampshire, as there are no licensed adult-use dispensaries. | Available from licensed Alternative Treatment Centers (ATCs). |
| Home cultivation | Not allowed. | Not allowed. |
| THC products | Marijuana-derived THC products cannot be legally purchased for recreational use. | Permitted through licensed ATCs for registered patients. |
| CBD and hemp products | Hemp-derived CBD products containing no more than 0.3% delta-9 THC are legal if they comply with federal and state law. | The same hemp rules apply in addition to access to medical cannabis products. |
Transportation is also regulated and non-medical cannabis must be stored in the trunk of a vehicle or, if there is no trunk, in the compartment least accessible to the driver. Violations can result in a $150 fine, and drivers under 21 may face additional license-related penalties.
What Future for Cannabis Legislation in New Hampshire?
Cannabis reform remains an active topic in the state, but progress has been slow. In recent years, lawmakers have introduced several bills to legalize and regulate recreational cannabis, including HB 186 in 2026. Other proposals have sought to automatically annul past cannabis possession convictions and expand the rights of medical cannabis patients, including allowing home cultivation and increasing possession limits. Still, these measures have also failed to advance.
Further reform is likely to remain on the legislative agenda, but any significant changes will depend on future legislative sessions and the state’s political landscape.
To Sum Up
Is marijuana legal in New Hampshire? The answer is partially. Recreational cannabis is illegal, although possession of small amounts has been decriminalized since 2017. Medical cannabis is legal through the state’s Therapeutic Cannabis Program. Hemp-derived CBD products that meet federal and state THC limits are also legal. Cannabis laws continue to evolve, so it’s important to stay informed about legislative developments. Always review the latest state regulations.
