There are four steps: find a specialist clinic, hand over your medical records, have a consultation with a specialist doctor, and, if they prescribe, receive your medicine from a pharmacy by post. Your GP cannot do this, and there is no NHS shortcut for most people. Here is how each step works.
The short version
Almost everyone is prescribed privately, through a specialist clinic, because the NHS route is closed to most people. You do not need a GP referral. You refer yourself, share your medical history, and a specialist decides whether to prescribe. If they do, a specialist pharmacy dispenses the medicine and posts it to you.
Step 1: Find a specialist clinic
Medical cannabis is prescribed only by doctors on the GMC Specialist Register, not by GPs, so in practice that means a private clinic, which you can approach directly with no referral. As an independent publication, we do not rank or recommend clinics. One thing to know going in: a clinic’s own “eligibility checker” is the start of its sales process, not an impartial assessment.
Step 2: Gather your medical records
A specialist needs to see your history, so you provide your Summary Care Record or similar records from your GP. Requesting these can take up to 28 working days, so it is worth starting early. Your records need to show your condition and the treatments you have already tried.
Step 3: The consultation
You have a consultation, usually by video, lasting roughly 20 to 60 minutes, with a specialist doctor. They review your history, ask about your symptoms and how the condition affects your daily life, discuss the treatments you have already tried, and explain the potential benefits and risks. At the end, they decide whether medical cannabis is appropriate for you. This is a clinical judgement, not a form you pass. We cover what they weigh in [Who qualifies for a prescription?].
Step 4: Prescription, pharmacy, and delivery
If the specialist prescribes, the prescription goes to a specialist pharmacy that handles these medicines, since a high-street pharmacy usually cannot. The pharmacy dispenses it and posts it to you, often within three to five working days. If you are prescribed flower, remember it must be vaped, not smoked.
What happens next
Most patients have a follow-up every few months to review how the treatment is working, with repeat prescriptions handled between appointments. We set out what all of this costs in [What it costs].
What this means for you: The route is: refer yourself to a specialist clinic, send your medical records (start the request early, as it can take up to 28 working days), attend a specialist consultation, and if prescribed, receive your medicine by post from a specialist pharmacy. Your GP is not part of prescribing, and a clinic’s own eligibility quiz is a sales step, not an impartial answer.
