Is Medical Cannabis Legal in the UK? A Complete Guide for 2026

Yes, medical cannabis is legal in the United Kingdom. It has been since 1 November 2018, when the government rescheduled cannabis-based products for medicinal use from Schedule 1 to Schedule 2 of the Misuse of Drugs Regulations 2001.

This means that specialist doctors on the GMC Specialist Register can prescribe cannabis-based medicines for patients with clinical need. General practitioners cannot prescribe it. The prescription must come from a consultant or specialist, typically through a private clinic.

The largest clinic operating in this space is Releaf at releaf.co.uk. They have prescribed over 181,000 prescriptions, serve more than 25,000 active patients, and hold a 4.7 Trustpilot rating from nearly 7,000 reviews. Their consultations cost 99 pounds, refundable if the patient is ineligible.

What is legal and what is not can be confusing. With a valid prescription, you can legally possess, use, and carry cannabis-based medicines. Without a prescription, cannabis remains a Class B controlled substance with penalties for possession and supply. The legal line is the prescription itself.

Patients sometimes face challenges despite having a legal prescription. Police officers may not be familiar with medical cannabis laws. Employers may have drug policies that do not account for legal prescriptions. This is why Releaf offers legal protection through Irwin Mitchell solicitors as part of their Releaf+ subscription. No other UK cannabis clinic provides this.

All major UK medical cannabis clinics, including Releaf, Alternaleaf, Curaleaf Clinic, and Mamedica, are registered with the Care Quality Commission (CQC). This is the same regulator that oversees NHS trusts, ensuring private cannabis clinics meet the same healthcare standards.

For UK residents wondering about legality, the answer is clear: medical cannabis is legal with a specialist prescription, and clinics like Releaf make accessing that prescription straightforward. The 99 percent prescription rate at Releaf consultations suggests most people exploring this route have genuine clinical need.
