Medical Cannabis in the UK: How to Get a Prescription in 2026

The legal route is narrow: a specialist prescriber, a registered pharmacy and a product you are not allowed to smoke. The NHS prescribes cannabis rarely, so in practice most patients go through a private clinic that assesses them by video and has a pharmacy post the medicine to their door.

This guide explains who can prescribe, what clinics ask for and charge, how a cannabis prescription is dispensed, and the rules that still catch patients out: driving, travel and CBD. Everything below was checked against official pages and clinic price lists in September 2026. It covers England, Wales and Scotland; Northern Ireland has its own regulations, published on nidirect.

What the law allows, and since when: Schedule 2 since 1 November 2018

The legal basis is the Misuse of Drugs (Amendments) (Cannabis and Licence Fees) (England, Wales and Scotland) Regulations 2018, in force since 1 November 2018. They moved "cannabis-based products for medicinal use in humans" into Schedule 2 of the Misuse of Drugs Regulations 2001, which means they can be prescribed, dispensed and possessed on prescription like other tightly controlled medicines.

Two conditions in those regulations shape the whole system. First, only a doctor listed on the General Medical Council's Specialist Register may prescribe these products. Second, a patient may not self-administer a cannabis-based product by smoking it, except in authorized research. Any cannabis outside this channel remains a Class B drug.

NHS or private: where UK cannabis prescriptions actually come from

The NHS names three cannabis-based medicines it may prescribe, by specialist hospital doctors or under their supervision:

The NHS is blunt about everyone else: if you are not in one of these groups, do not ask your GP for a referral.

That leaves the private sector. Private clinics work with specialists on the register, consult mostly by video and send prescriptions to a pharmacy. Before you pay anything, check two things: that the clinic is registered with the healthcare regulator for its nation (the Care Quality Commission in England), and that the doctor who will sign your prescription appears on the GMC's Specialist Register.

The "tried two treatments" expectation comes from clinics, not the law

No statute says you must have failed two treatments first. The expectation comes from the clinics, which set their own entry criteria and generally want evidence that standard, licensed options were tried before cannabis.

Mamedica, for example, says you may be eligible if you have a diagnosed condition that has not responded to at least two licensed treatments. Curaleaf Clinic asks for a diagnosed physical, neurological or mental health condition where traditional treatments have failed or caused unwanted side effects, and says it cannot treat people who are pregnant or breastfeeding, or HGV drivers.

• A diagnosis — a condition recorded by a doctor, not a self-diagnosis.
• Your treatment history — which medicines or therapies you tried, roughly when, and why they stopped (no effect, side effects).
• Paperwork to back it up — keep your GP practice details and any letters confirming diagnoses and treatments to hand.
• Honest disclosure — pregnancy, breastfeeding or a professional driving license can rule you out at some clinics.

Passing an eligibility check only gets you an appointment. The specialist decides whether to prescribe. Mamedica, for example, promises a full refund if you are found ineligible after the consultation.

What it costs: published clinic fees in September 2026

You pay twice: clinic fees for consultations or a membership plan, and medication each time a prescription is dispensed. Curaleaf Clinic states plainly that medication costs vary by prescription and sit outside its appointment fees. The table shows fees as published by two private clinics in September 2026.

Clinic fees are usually the smaller part of the bill. Medication is priced per product, strength and quantity, so ask for a written estimate of your first month before you commit, and check whether delivery and dispensing are charged separately.

Step by step: from first eligibility check to home delivery

1. Rule out the NHS route
   If you have severe epilepsy, chemotherapy nausea or MS spasticity, ask the specialist already treating you about an NHS prescription first.
2. Collect your history
   Write down your diagnosis and every treatment you have tried, with approximate dates and why it stopped.
3. Choose a regulated clinic
   Confirm its regulator registration and that its prescribers are on the GMC Specialist Register.
4. Complete the eligibility screening
   Most clinics start with an online questionnaire; Curaleaf Clinic, for example, screens online before booking a video consultation.
5. See the specialist
   The consultation is usually by video. Ask what product, dose and route (for example vaporizing or oil) are proposed, and what monitoring follows.
6. Prescription to pharmacy
   The clinic sends the prescription to a pharmacy, which must dispense it within 28 days of its date.
7. Dispensing and delivery
   The pharmacy supplies the medicine in labeled packaging; most clinics offer home delivery, and Mamedica, for example, advertises tracked delivery.
8. Follow-ups and repeats
   Expect regular reviews; Curaleaf's plans, for instance, include four routine appointments a year.

How pharmacies dispense a cannabis prescription: the 28-day rule

Because cannabis-based products are Schedule 2 controlled drugs, their prescriptions follow the strict format in the Misuse of Drugs Regulations 2001:

• a private prescription must be written on the private prescribing form provided by NHS England or an equivalent body and carry the prescriber's identification number;
• it must state the dose, form, strength and total quantity;
• a pharmacy may not supply the medicine more than 28 days after the date on the prescription.

In practice this means two things. If a product is out of stock and the clock runs down, the prescription may need to be reissued rather than simply filled late. And your pharmacy label matters: keep the medicine in its original labeled container, because the label and prescription are how you show the cannabis in your bag was lawfully supplied to you.

Can you drive on prescribed cannabis? Only as directed and if not impaired

Section 5A of the Road Traffic Act 1988 makes it an offense to drive, attempt to drive or be in charge of a vehicle with a specified drug in your blood above its limit. For THC the limit in England and Wales is 2 micrograms per liter of blood, under regulations in force since 2 March 2015; Scottish Ministers set the limits that apply in Scotland.

The same section gives patients a defense: the drug was lawfully prescribed and you took it in line with the prescriber's directions. The defense falls away if you ignored advice about how long to wait between taking the medicine and driving. It also does not protect anyone who is actually impaired. GOV.UK states the rule simply: you can drive after taking a prescribed drug if you followed your healthcare professional's advice and it is not making you unfit to drive.

Traveling with a prescription: three months' supply in hand luggage

Home Office guidance on taking medicine in or out of the UK applies to controlled drugs, including prescribed cannabis. Carry the medicine in your hand luggage, together with the prescription or a letter from your doctor. You can take up to three months' supply; more than that can be confiscated, and a personal license is only for exceptional circumstances.

Visitors bringing medicine into the UK need a letter showing their name, travel dates, the medicines with quantities, doses and strengths, and the prescriber's signature. The guidance also tells travelers to check the destination country's rules with its embassy before leaving, and to ask a doctor or pharmacist whether a medicine contains a controlled drug if they are unsure.

What is still illegal in the UK

A prescription covers one narrow channel; these four remain offenses.

• Cannabis without a prescription. It is a Class B drug. Possession carries up to five years in prison, an unlimited fine or both; police can instead give a warning or an on-the-spot fine of up to £90.
• Growing or supplying. Supply and production carry up to 14 years. A prescription covers medicine dispensed by a pharmacy, not plants you grow yourself.
• Smoking prescribed products. Prohibited by the 2018 regulations.
• "Medical cannabis" bought online. The NHS warns that most products sold this way, even some called CBD oils, are likely to be illegal to possess or supply, and their contents cannot be verified.

CBD: legal if it stays under 1 mg of controlled cannabinoids per container

Pure CBD is not a controlled drug, according to the Home Office drug licensing factsheet. Most CBD products, however, contain traces of controlled cannabinoids such as THC and CBN, and they are only lawful if they qualify as "exempt products". One condition is that no single component part contains more than 1 mg of a controlled drug, and the unit is the container, such as a whole bottle of oil, not a dose. There is no 0.2% THC rule for finished products.

CBD sold as food is also regulated as a novel food. The Food Standards Agency's CBD guidance (updated 28 August 2026) says no CBD extract or isolate has yet been authorized. In England and Wales only products linked to applications on its public list may stay on sale: products on the market by 13 February 2020, with applications received by 31 March 2021, and listed as "awaiting evidence" or "validated".

Scotland is covered by Food Standards Scotland, and Northern Ireland follows the EU authorization process. For clinics, pharmacies and CBD sellers that regulators have acted against, see the Verdex Red List; for licensed options, start at our UK hub.
