Medical Cannabis in Northern Ireland: Access, Law and Clinics in 2026

When the law changed, Northern Ireland’s Department of Health said cannabis-based products for medicinal use could be prescribed by specialist doctors for patients with an unmet clinical need – mirroring similar reforms in England, Scotland and Wales.

Northern Ireland’s official patient guidance says specialist doctors can prescribe cannabis-based medicines where there is a “clinical need” and other treatments “are not suitable or have not helped”. However, it says the medicines are “only likely to benefit a very small number” and are prescribed through the health service for only “a few patients”.

Campaigner Ashley Guerriero, who is calling for changes to medical cannabis policy in the Republic of Ireland, recently told Cannabis Health that problems getting medical cannabis came up repeatedly in conversations with patients across the country “from Mayo to Dublin to Cork”.

“They don’t want to engage [with the] black market” but “they can’t get medical” treatment, he said.

Who can prescribe medical cannabis in Northern Ireland?

Prescribing of unlicensed cannabis-based products for medicinal use is restricted to doctors on the General Medical Council’s Specialist Register – a list of doctors who have completed specialist training and are recognised as specialists in a particular area of medicine.

When the law changed in 2018, Northern Ireland’s Department of Health said prescribing decisions should be taken by “expert clinicians” and informed by evidence on “quality, safety and effectiveness”. 

For this reason, medical cannabis can only be prescribed initially by specialist doctors and is not available directly from GPs.

And for patients seeking treatment privately, a specialist will assess their condition, previous treatments and whether medical cannabis is appropriate for them.

Patients may also choose to carry a medical cannabis identification card, although these are not a legal requirement and do not replace evidence of a prescription, as previously examined by Cannabis Health. 

Northern Ireland’s official guidance advises patients to keep their medicine in its original packaging with the dispensing label, alongside a copy of their prescription and, where available, a letter from their prescribing doctor.

Can you get medical cannabis through the health service in Northern Ireland?

Although medical cannabis can legally be prescribed in Northern Ireland, access through Health and Social Care (HSC) remains limited.

Northern Ireland’s patient guidance says medical cannabis is prescribed through the health service for only “a few patients”, with “limited scientific evidence” around its safety and effectiveness and few licensed products available.

It says specialist prescribing may be considered for certain rare forms of epilepsy, muscle stiffness and spasms (spasticity) associated with multiple sclerosis where other treatments have not helped, and chemotherapy-induced nausea or vomiting where anti-sickness treatments have not worked.

A prescription would only be given when considered in the patient’s “best interests,” and other treatments had not worked or were unsuitable. 

Can you access medical cannabis privately in Northern Ireland?

Patients in Northern Ireland can access medical cannabis through private UK clinics, including providers which offer consultations remotely rather than through a physical clinic in Northern Ireland.

Patients accessing medical cannabis privately need to pay for their treatment, which can include consultations, medication, repeat prescriptions and delivery charges depending on the provider.

Can medical cannabis be delivered to Northern Ireland?

Yes. Patients in Northern Ireland with a valid private medical cannabis prescription can have their medication dispensed and delivered to their home.

Can you travel between Northern Ireland and Great Britain with medical cannabis?

Travelling between Northern Ireland and England, Scotland or Wales does not involve crossing an international border, but patients carrying medical cannabis should still be able to demonstrate that the controlled medicine has been lawfully prescribed to them.

Northern Ireland’s guidance recommends keeping cannabis medicines in their original packaging with the dispensing label, as well as carrying a copy of the prescription and, where available, a letter from the prescribing doctor. 

Patients should check requirements before travelling, particularly if their journey passes through another jurisdiction.

Can you take medical cannabis from Northern Ireland into the Republic of Ireland?

Medical cannabis patients in Northern Ireland cannot take their prescribed medication across the border into the Republic – despite being legally prescribed it in the UK.

Current Irish Department of Health guidance states that prescribed cannabis-based products cannot be brought into Ireland, creating a particular issue for patients in Northern Ireland who regularly travel across the border.

Guerriero – who launched a petition in October 2025 calling for a review and expansion of Ireland’s medical cannabis programme – said cross-border travel was one of the areas his campaign wants to see reformed.

He told Cannabis Health that patients could face problems even when carrying their medication with a valid UK prescription and supporting documentation – adding that his campaign is focused on bringing regulators, medical cannabis businesses and other stakeholders together to reform existing rules.

He described speaking to one UK patient who was stopped while travelling with 20g of prescribed cannabis and, according to Guerriero, faced being arrested for trafficking.

“The patients are still being treated like criminals,” he said. “It needs to stop.”

One patient who has experienced this first-hand is UK medical cannabis patient Jason Pickering, who spoke with Cannabis Health after around £360 worth of his prescription was confiscated at Dublin Airport in December 2024 – in an experience his family described as “horrendous” and which left him feeling effectively “banned” from Ireland.

Can you drive while taking medical cannabis in Northern Ireland?

Yes, but it is against the law to drive while “unfit through drugs” – and Northern Ireland’s guidance says the law does not distinguish between illegal and prescribed drugs.

Patients are advised to follow their doctor’s instructions and check their medication for “warning messages about driving or operating machinery”. Those who are unsure should speak to their doctor, pharmacist or another healthcare professional before driving.

The guidance says police can carry out a roadside impairment test if they suspect someone is driving under the influence of drugs, while a saliva test can be used to detect substances including cannabis. Drivers suspected of being unfit through drugs can also be arrested and required to provide a blood sample.

If police believe someone “might be impaired”, they can carry out a roadside Field Impairment Test and use a saliva test which can detect cannabis. Drivers believed to be unfit through drugs can be arrested and required to provide a blood sample. 

An Antrim mother-of-two with epilepsy previously told Cannabis Health she felt like a “second-class citizen” after losing her driving licence following a medical review by Northern Ireland’s driving licence authority. 

Elle Humphries, whose name was changed to protect her identity, said medical cannabis had helped her become seizure-free – but losing her licence had taken a huge toll on family life in rural Northern Ireland, impacting her children, putting their safety at risk and adding “layers of stress”.

Cannabis Health has also examined the wider issues around medical cannabis and driving in the UK, including impairment, interactions with other medicines and what patients should consider if they are stopped by police. 

Is medical cannabis access different in Northern Ireland from the rest of the UK?

The rules around prescribing medical cannabis are broadly the same across the UK. When the law changed in 2018, Northern Ireland’s Department of Health said its approach would “mirror” England, Scotland and Wales, allowing specialist doctors to prescribe cannabis-based medicines for an “unmet clinical need”.

But there are some differences for patients in practice, particularly because Northern Ireland shares a land border with the Republic of Ireland. A prescription that is legal in Northern Ireland does not automatically allow a patient to take their medical cannabis across the border.

A prescription that is legal in Northern Ireland does not automatically allow a patient to take their medical cannabis across the border – part of a system Guerriero wants regulators and policymakers to “come to the table” to address due to how it leaves, in his view, legal patients being “treated like criminals”.

Driving is also handled differently. Northern Ireland has its own driving licence authority, rather than the DVLA which covers Great Britain, and patients may have to deal with it if their medical fitness to drive is reviewed.

Private treatment, meanwhile, is available through UK clinics which accept Northern Irish patients, with consultations often carried out online and medication delivered to their home.

What should patients know before seeking treatment?

Being able to legally prescribe medical cannabis does not mean it will be suitable for every patient. Northern Ireland’s official guidance says a specialist will consider whether there is a “clinical need” and whether other treatments “are not suitable or have not helped”.

For those going private, the cost of treatment can extend beyond the first appointment to ongoing consultations and medication.

Patients who drive should also check how their prescription could affect them behind the wheel and must not drive if they are impaired.

And those travelling south need to be particularly careful – a UK prescription does not automatically allow medical cannabis to be taken across the border into the Republic of Ireland, so patients should check the current Irish rules before travelling.

Medical cannabis and NHS pathways

The challenges around obtaining medical cannabis through mainstream healthcare will also be discussed at the Cannabis Health Symposium in London on 26 November.

A dedicated session on cannabis-based medicines and NHS pathways will look at the current prescribing landscape, referral pathways and some of the barriers preventing wider use of cannabis-based medicines in UK healthcare.
