Possession and Supply Limits — RSA 126-X:2
A qualifying NH patient may possess up to 2 ounces (56.7 g) of usable cannabis at one time, with a 10-day rolling purchase cap of 2 ounces. There is no separate concentrate weight limit — concentrates count toward the 2-ounce cap by the cannabis-equivalent weight assigned at the dispensing ATC. Caregivers may possess up to the same 2-ounce limit on the patient’s behalf.
The 10-day window is rolling, not calendar-based: each purchase consumes “allotment” that becomes available again ten days after the original transaction. ATCs track this in real time through the patient registry, so attempting to exceed the cap by visiting multiple ATCs will not work — the system will block the purchase at the second dispensary.
Allowed Product Forms
For roughly the program’s first three years, NH dispensaries could sell only tinctures, oils, capsules, salves, and patches — no flower, no edibles. Flower was added in 2019 following legislative action and a public-comment process. The current product menu generally includes:
| Form | Allowed? | Notes |
|---|---|---|
| Flower and pre-rolls | Yes | Added 2019. Smoking permitted (NH does not have Utah’s vaporization-only rule). |
| Vape cartridges | Yes | Standard at all three operators. |
| Concentrates (live resin, rosin, distillate, kief, hash) | Yes | Count toward 2 oz cap by cannabis-equivalent weight. |
| Tinctures and oils | Yes | Original 2016 product class. |
| Capsules | Yes | Common for chronic-pain and PTSD patients. |
| Edibles — gummies, chocolates, baked goods | Yes (limited) | Selection narrower than MA/ME rec markets. |
| Topicals (salves, balms, transdermal patches) | Yes | |
| Home-grown flower | No | Cultivation is a felony, even for patients and caregivers. |
| Smokable flower in public | No | RSA 155:64 prohibits indoor public smoking. |
NH does not impose the 300 mg per-edible cap that applies under RSA 318-B:2-c to out-of-state edibles brought into NH for personal use. Inside the program, edible dosing is set by ATC product specs and not by a fixed statutory milligram cap, although ATCs typically follow the New England industry norm of 5–10 mg per serving.
Home Cultivation Is Prohibited
New Hampshire is the only New England state that bars patients from growing their own medicine, and one of only roughly 14 medical-state holdouts on home grow nationally. Cultivation of any amount — even a single plant — is a felony under RSA 318-B:26. The NH home-grow ban applies to both qualifying patients and registered caregivers; nothing in RSA 126-X carves out a personal-cultivation right.
Multiple home-grow bills have passed the House only to die in the Senate Judiciary Committee. HB 1231 (2024) and HB 53 (2025) are the most recent examples, both passing the House and both killed in the Senate after a tabling motion by Sen. Daryl Abbas (R). Watch for another medical home-grow attempt in 2026 or 2027 — advocates view it as the most plausible incremental reform absent a full rec push.

HB 1278 Reciprocity — Visiting Patients
Until June 28, 2023, New Hampshire offered no meaningful reciprocity. That changed administratively, then more broadly under HB 1278 (effective October 1, 2024), which removed the prior three-purchases-per-year cap. Visiting patients from any U.S. state, U.S. territory, or Canada with valid out-of-state medical cannabis credentials may now purchase from any NH ATC at the same frequency as in-state patients (subject to the 2 oz / 10-day cap).
Visitors must show:
- A valid out-of-state medical cannabis ID card from any U.S. state, U.S. territory, or Canada
- A matching photo ID (driver’s license, state ID, or passport)
NH does not require reciprocal patients to share a qualifying NH condition — if the home-state program issued the card, NH ATCs will honor it. This makes NH ATCs an unexpected option for travelers in the region, and it also means a patient with, for example, a Maine or Massachusetts medical card can buy at a NH ATC during a Granite-State trip without any prior application or NH residency.
Public Consumption and Transport
Public cannabis consumption is prohibited regardless of TCP status. RSA 155:64 prohibits indoor public smoking, including cannabis. Outdoor public consumption (parks, beaches, sidewalks, parking lots) is also prohibited and exposes the user to criminal liability under RSA 318-B notwithstanding the TCP card.
The 2024 open container law (SB 426, effective January 1, 2025) is codified at RSA 265-A:44, II-a. It requires non-therapeutic cannabis to be transported in the trunk only, with a $150 fine and up to a 60-day driver’s license suspension for violation. Therapeutic cannabis (cannabis acquired through RSA 126-X) is exempt from the open container rule, provided the patient holds a valid registry card and the cannabis is in original ATC packaging.
Federal Employment Caveat
State legal protections under RSA 126-X do not extend into federal employment. Federal employees, federal contractors at Pease Tradeport and elsewhere, military personnel (including 157th Air Refueling Wing Air National Guard members), and federal-grant recipients at NH universities remain subject to the federal Drug-Free Workplace Act and DoD Instruction 1010.16. A valid TCP card does not shield against federal drug-test consequences.
