Quick Answer: New Hampshire Cannabis Laws at a Glance
| Category | Status |
|---|---|
| Medical cannabis | Legal, regulated program |
| Adult-use / recreational | Illegal |
| Small-amount possession | Decriminalized (civil fine, not criminal) |
| Home cultivation | Prohibited for all, including medical patients |
| Federal tax treatment | IRC §280E applies; ordinary deductions disallowed |
New Hampshire permits medical cannabis access and decriminalizes small-amount possession. However, it prohibits adult-use and home cultivation. State-legal cannabis businesses face a challenging federal tax structure that disallows ordinary business deductions.
New Hampshire's Therapeutic Cannabis Program: Eligibility and Access
New Hampshire's medical cannabis program is managed by the NH Department of Health and Human Services (DHHS). This program offers the only legal avenue for cannabis access within the state.
Patient Eligibility and Qualifying Conditions
To enroll, patients need a written certification from a licensed practitioner confirming a qualifying medical condition. Historically, these conditions included cancer, glaucoma, HIV/AIDS, hepatitis C, ALS, muscular dystrophy, Crohn's disease, multiple sclerosis, and PTSD. For the most current and official list of qualifying conditions, consult the NH DHHS directly.
Who Can Write a Recommendation
Since 2019, House Bill 350 has authorized physician assistants to recommend medical cannabis (NH HB 350, 2019). This legislation broadened the range of practitioners who can certify patients.
The Three-Month Waiting Period
Governor Sununu vetoed legislation that aimed to remove the mandatory three-month waiting period for medical cannabis recommendations. However, the legislature later overrode this veto (NORML, 2019 Vetoed Legislation). Check with the NH DHHS for the current waiting period requirements.
Home Cultivation: Still Prohibited
Medical patients are not permitted to grow their own cannabis. Governor Sununu vetoed HB 364 (2019), which would have allowed registered patients to cultivate up to three plants at home. In his veto message, the Governor stated that home cultivation would "make the job of law enforcement significantly more difficult" and could decrease patient visits to licensed dispensaries. The legislature did not override this veto, so the prohibition remains in effect.
Dispensaries: Non-Profit Requirement Remains
New Hampshire's licensed dispensaries, known as Alternative Treatment Centers (ATCs), must operate as non-profit entities. SB 145 (2019) attempted to allow for-profit operations, but Governor Sununu vetoed it, expressing concern that the bill "would represent too great a step toward a dangerous path of industrial commercialization of the marijuana industry in New Hampshire." For information on current ATC locations and their operational status, consult the NH DHHS.
Decriminalization and Penalties for Cannabis Possession in New Hampshire
New Hampshire decriminalizes the possession of small amounts of cannabis. For first or second low-level offenses, it is treated as a civil infraction, not a criminal offense. This typically results in a fine instead of arrest or a criminal record. Decriminalization does not equate to legalization; there is no legal supply chain for recreational users, and possessing larger amounts or engaging in distribution remains a criminal offense.
Possession Thresholds and Penalties
Possessing three-quarters of an ounce (¾ oz) or less of cannabis is a civil violation for a first or second offense, punishable by a fine. Consult the NH General Court website for specific statutory language and fine schedules, as the legislature may adjust these.
| Situation | Classification | Consequence |
|---|---|---|
| Possession ≤ ¾ oz (1st or 2nd offense) | Civil violation | Fine (consult NH General Court) |
| Possession ≤ ¾ oz (3rd+ offense) | Class B misdemeanor | Criminal record possible |
| Possession > ¾ oz | Criminal offense | Consult NH General Court for penalties |
| Distribution / sale | Criminal offense | Consult NH General Court for penalties |
A third offense for possessing a small amount of cannabis is elevated to a Class B misdemeanor, which can lead to a criminal record. Any distribution activity, regardless of the quantity involved, is considered a criminal matter. Refer to the NH General Court website for applicable statutes.
Annulment of Low-Level Convictions
House Bill 399 (2019) allows individuals with low-level marijuana convictions to petition the court for record annulment (NH HB 399, 2019). This process is not automatic; it requires filing a petition and obtaining court approval. Individuals seeking to clear older convictions should consult an attorney experienced in New Hampshire criminal procedure and relevant annulment statutes.
Federal Tax Implications for New Hampshire Cannabis Businesses (IRC §280E)
Federal tax law applies to cannabis businesses irrespective of state legality, creating a substantial financial burden for New Hampshire operators.
What IRC §280E Does
Internal Revenue Code (IRC) §280E prohibits deductions for ordinary and necessary business expenses for any trade or business involved in trafficking Schedule I or II controlled substances. Since cannabis remains a Schedule I
