Cannabis in New Hampshire: Laws, Legal Status, Recreational & Medical Use

New Hampshire occupies a unique position in the New England region, maintaining a policy of decriminalization rather than full recreational legalization. While every surrounding state has moved to a tax-and-regulate model for adult use, New Hampshire relies on a strictly regulated medical program and civil violations for personal possession. The state’s Therapeutic Cannabis Program, established in 2013, has seen significant expansion in recent years, granting medical providers broad discretion to certify patients for therapeutic use. Despite consistent public support and frequent legislative proposals to establish a retail market, the state continues to focus on refining its medical framework and maintaining its decriminalized status for the general public.

Cannabis Legal Status in New Hampshire

New Hampshire permits medical cannabis use for registered patients with a valid registry ID card. For recreational users, possession of small amounts has been reduced from a criminal offense to a civil violation. However, the state remains a “non-grow” state, meaning that neither medical patients nor recreational users are permitted to cultivate their own cannabis at home.

Recreational Cannabis Laws in New Hampshire

Legal Age Requirements

There is no legal age for recreational cannabis as it is prohibited. For the medical program, adults must be 18 or older, while minors require a parent or legal guardian to serve as a designated caregiver.

Possession Limits

Decriminalization is not legalization. For adults 18 and older, possession of up to three-quarters of an ounce of marijuana or five grams of hashish generally receives a violation-level penalty. The separate rule for regulated infused products applies at age 21, covers no more than 300 milligrams THC, and has source and original-packaging conditions.

Under RSA 318-B:2-c, the first two qualifying offenses carry $100 fines. A third within three years can carry up to $300. A fourth, with the required prior convictions alleged, is a class B misdemeanor. Forfeiture also applies. Larger quantities fall outside these reduced penalties. Registered therapeutic patients have separate authorization.

Where Cannabis Can Be Purchased

Recreational cannabis cannot be purchased legally in New Hampshire. Registered medical patients must purchase from one of the state’s licensed Alternative Treatment Centers (ATCs).

Public Consumption Laws

Public smoking and vaping are prohibited, including for therapeutic patients. Under RSA 265-A:44, nontherapeutic marijuana in a passenger area must generally remain in its original sealed container. Open packaging has separate trunk or storage requirements, with distinctions for drivers and passengers. Authorized therapeutic cannabis is excluded from that particular marijuana transport provision; impaired driving remains prohibited.

Home Cultivation

Home cultivation of cannabis is illegal in New Hampshire for all users. Growing any amount of cannabis is classified as a criminal offense, and attempts to legalize medical home-grow have historically been blocked in the state legislature.

Medical Cannabis in New Hampshire

Medical Cannabis Program

The Therapeutic Cannabis Program permits provider discretion for adults 21 and older when potential benefits likely outweigh risks for a debilitating or terminal condition or symptom. This is not a general discretion category for all patients aged 18 and older. Providers must satisfy the statutory licensing and active DEA-registration requirements; certain Maine, Massachusetts, and Vermont clinicians are also eligible.

Qualifying Conditions

Listed conditions and symptoms include cancer, glaucoma, HIV/AIDS, multiple sclerosis, chronic pain, PTSD, autism, and generalized anxiety disorder. Some pathways require both a condition and a qualifying symptom, and autism and opioid-use-disorder certifications have additional requirements. Consult the complete eligibility criteria.

Patient Registration

Patients must obtain a “Written Certification” from their healthcare provider and apply to the Department of Health and Human Services (DHHS). Once approved, they receive a Registry ID card, which must be presented at an ATC.

Medical vs Recreational Differences

Medical patients may possess two ounces of usable cannabis. The program rules separately limit acquisition to two ounces in a ten-day period; a caregiver does not provide an extra personal allowance for the same patient.

Qualifying visitors with valid documentation from another U.S. jurisdiction or Canada may use ATCs under New Hampshire’s rules. Medical authorization does not permit home cultivation.

Is CBD Legal in New Hampshire?

Some hemp products may be lawful, but food, supplement, and THC restrictions apply. A hemp label or online shipping offer does not establish that every formulation may be sold in New Hampshire.

Hemp-Derived CBD

The current hemp statute does not authorize sales of hemp-derived products containing natural or synthetic THC above 0.3% dry weight, including delta-8 and other isomers. Additional amendments take effect January 1, 2027, as described below. Do not treat the upcoming definition as already effective.

Cannabis-Derived CBD

Hemp is a type of cannabis. Products regulated as therapeutic cannabis require the ATC and patient framework; the phrase “cannabis-derived CBD” alone does not determine legal classification.

CBD Food and Beverage Laws

The FDA does not permit adding CBD to conventional food introduced into interstate commerce. New Hampshire’s Liquor Commission guidance also identifies CBD as an unapproved food additive and prohibits its addition to alcoholic beverages by licensees. Clear labels and the absence of medical claims do not override ingredient restrictions. Therapeutic cannabis products have a separate state framework.

Where to Buy Cannabis in New Hampshire

Licensed Cannabis Dispensaries

Qualified patients must purchase from one of the state’s licensed Alternative Treatment Centers. These centers are located in Concord, Dover, Lebanon, Merrimack, and other areas. Available products include:

• Cannabis flower and pre-rolls
• Concentrates and oils
• Infused edibles and capsules
• Topical creams and patches

Online Ordering and Pickup

Most ATCs allow patients to browse menus and pre-order online for in-store pickup. However, home delivery of cannabis is not currently permitted under the state’s therapeutic cannabis rules.

Cannabis Taxes

New Hampshire has no general sales tax. A proposed adult-use franchise fee is not a current tax on therapeutic patients. There is no authorized recreational retail market to which such a proposed system can presently apply.

Cannabis Penalties and Restrictions

Small-quantity violations and repeat offenses follow the thresholds above. For possession outside those provisions, RSA 318-B:26 governs applicable criminal penalties. Do not rely on a blanket $350 maximum or assume every case has the same jail exposure.

Medical registration does not authorize public smoking or vaping, impaired driving, or home cultivation. Vehicle possession is separately regulated under RSA 265-A; decriminalization does not remove transport restrictions.

Future Cannabis Legislation in New Hampshire

ATC greenhouse cultivation: SB 468 became law after the August 19, 2026 veto override, as recorded in its official legislative history. Chapter 344 lets ATCs seek authorization for greenhouse cultivation under departmental rules. This does not authorize patients or other residents to grow at home.

Hemp changes: SB 624, Chapter 275, approved July 2, 2026, changes the hemp definition to a total-THC standard including THCA and strengthens related prohibitions. Those hemp amendments take effect January 1, 2027. The enacted hemp definition uses a 0.3% total-THC dry-weight standard.

These measures do not establish an adult-use retail market. Proposed legalization or home-growing bills must be distinguished from enacted law.
