Beginner's Guide to Medical Cannabis in the UK
If you’re considering medical cannabis for the first time, this guide will walk you through the basics. Medical cannabis (CBPMs) has been available on prescription in the UK since 2018. This page explains what new patients need to know in clear, straightforward terms.
Important Disclaimer: This page is for educational purposes only and does not constitute medical advice. Medical cannabis is a prescription-only medicine. Always consult a qualified specialist doctor. Treatment suitability is decided on an individual clinical basis.
What Is Medical Cannabis?
Medical cannabis refers to cannabis-based products prescribed by specialist doctors to help manage symptoms when other treatments have not been effective enough. It contains natural compounds from the cannabis plant, primarily THC and CBD, in controlled doses and quality-assured forms.
It is not the same as recreational cannabis or high-street CBD supplements.
Who Might Consider Medical Cannabis?
Patients who may be eligible often have:
• Chronic pain
• Anxiety or PTSD (under specialist assessment)
• Sleep issues
• Epilepsy (certain types)
• Multiple sclerosis spasticity
• Other conditions where standard treatments have not provided sufficient relief
Eligibility is always determined by a specialist doctor after reviewing your medical history.
The Step-by-Step Patient Journey for Beginners
Research & Self-Assessment
Learn the basics (you’re here now) and check if you have a diagnosed condition with previous treatments tried.
Choose a Clinic
Private specialist clinics are the most common route. Look for CQC-registered clinics with GMC Specialist Register doctors.
Pre-Screening
Most clinics offer a free or low-cost initial questionnaire.
Submit Medical Records
You will need to provide relevant medical history (usually from your GP).
Specialist Consultation
Video or in-person appointment (£99–£200 range typically). The doctor will assess whether medical cannabis is clinically appropriate.
Prescription & Delivery
If approved, the prescription is sent to a licensed pharmacy and delivered securely to your door.
Follow-up Care
Regular reviews to monitor effects, adjust dosage, and ensure safety.
What to Expect During Treatment
Forms prescribed: Most beginners start with oils. Some may be prescribed vaporised dried flower.
Onset time: Effects vary — oils can take 30–90 minutes; vaporised flower acts faster.
Titration: Doctors usually start with low doses and slowly increase (“start low, go slow”).
Side effects: Possible dry mouth, drowsiness, dizziness — your doctor will discuss these.

Common Beginner Questions
Will I get “high”?
Medical products are prescribed for therapeutic effect. Some THC-containing products can produce psychoactive effects; your doctor will choose strains and ratios suited to your needs.
How fast can I start?
Many private clinics can complete the process within 1–4 weeks.
Do I need a GP referral?
Usually not required for private clinics.
Is it expensive?
Consultations and medication are paid privately. Costs vary widely depending on dosage and product.
Can I drive?
There are strict rules around THC and driving. Follow your doctor’s advice and be aware of legal limits.
Important Safety Notes
• Never smoke medical cannabis — vaporisation is the medically preferred method for flower.
• Store medication safely, away from children.
• Inform your doctor about all other medications (potential interactions).
• Carry your prescription when travelling.
