Medical Marijuana became legal in New Hampshire in 2013 through the signing of HB573, with dispensaries (in the form of “Alternative Treatment Centers”) opening in 2016. State regulations allow for 4 to operate, all of which are now open.

Though adult use cannabis is illegal in the state, the House of Representatives has passed a bill in attempt to legalize personal possession and home cultivation (but no tax-and-regulate system of sales), which they hope to get approved by the Governor and Senate. Governor Chris Sununu has stated his opposition to legalization, despite past bicameral support.

Medical marijuana in New Hampshire is allowed in a variety of preparations, including dried flower, concentrates, capsules, tinctures, edibles (including baked goods and candied preparations), sprays, lotions, and other transdermal preparations.

Medical cannabis consumption is only permitted in private residences at this time. Consumption is not allowed in public, including a public bus or other public vehicle, or any public park, public beach, or public field.

Driving Under the Influence

The regulations for cannabis in New Hampshire states that medical marijuana patients in the state are not exempt from arrest or prosecution for being under the influence of cannabis while, “operating a motor vehicle, commercial vehicle, boat, vessel, or any other vehicle propelled or drawn by power other than muscular power.”


Registered patients are allowed to assign a caregiver, who must also be registered with the state’s medical marijuana program. A caregiver may only serve as a caregiver for one patient at a time.

Transporting Marijuana

Patients can transport up to their allowable limit of 2 ounces, along with documentation of their patient status and cannabis products.


New Hampshire extends limited reciprocity to out-of-state card holders, officially called a “visiting qualified patient.” Visiting patients cannot purchase cannabis at a state Alternative Treatment Center, nor can they be given medical cannabis from an in-state patient. However, visiting patients are allowed to possess cannabis in the approved New Hampshire forms and amounts, so long as they have a qualifying condition recognized by the state.


Medical cannabis patients are currently not allowed to grow their own cannabis. As of February 2020, the state senate passed SB420, which would allow for home cultivation and awaits house and governor approval. However, past efforts have failed despite support from the House and Senate due to veto by Gov. Sununu.


Cannabis delivery is not permitted in New Hampshire.
