🌱 When Did Medical Cannabis Become Legal in the UK

Medical cannabis became legal on 1 November 2018. This law change allowed specialist doctors to prescribe Cannabis Based Products for Medicinal Use, known as CBPMs. These are regulated medicines produced under strict pharmaceutical standards and supplied through licensed pharmacies.

The change happened after several high profile medical cases involving children with severe epilepsy. A government review followed, and certain cannabis based medicines were rescheduled to allow legal medical use.

🌱 Is Medical Cannabis Actually Legal Right Now

Yes. Medical cannabis is completely legal in the UK when it meets the rules set by UK regulation.

To be legal it must
• Be a regulated CBPM
• Be prescribed by a specialist doctor
• Be dispensed by a licensed pharmacy

Anything outside this framework is not legal. This includes street cannabis, home growing, and THC products bought online without a prescription.

🌱 Who Can Prescribe Medical Cannabis in the UK

Only doctors listed on the General Medical Council specialist register can prescribe medical cannabis. These are experienced consultants who work in clinical areas such as pain, neurology, psychiatry, oncology and palliative care.

GPs cannot prescribe medical cannabis. They can support your application and share your medical history, but the prescription must come from a specialist.

Private clinics are currently the main route for UK patients, since NHS access is extremely limited and usually restricted to a very small number of conditions.

🌱 What Medical Cannabis Products Are Available in the UK

Here is the most accurate and up to date information for 2025.

Currently available through UK medical cannabis clinics
• Dried cannabis flower for vaporisation
• Cannabis oils
• Vape cartridges

These are the three active categories of CBPMs that clinics and pharmacies are supplying today.

Previously available but discontinued
• Cannabis gummies
Gummies were briefly available through a limited number of suppliers, but they were discontinued some time ago and are no longer prescribed in the UK. They may return in the future, but there is no confirmed timeline.

Not available in the UK
• Edibles
• Chocolates
• Drinks
• Food based THC products
• Any form of combustible smoking product

All medical products must also meet pharmaceutical standards, undergo testing and be batch controlled.

🌱 What Counts as Legal Medical Cannabis

Legal medical cannabis in the UK must be
• A recognised CBPM
• Made under strict pharmaceutical conditions
• Tested for consistency and purity
• Supplied in sealed medical packaging
• Dispensed through a licensed UK pharmacy

This is very different from CBD oils sold online or in high street shops, and completely different from illegal cannabis sold on the black market.

🌱 Can You Legally Possess Medical Cannabis in the UK

Yes. Once you have a valid prescription, you are legally allowed to possess your medication anywhere in the UK.

To stay safe and avoid misunderstandings
• Keep your medication in its original pharmacy packaging
• Carry a copy of your prescription or clinic letter
• Keep any patient information leaflet if one is supplied

Police can verify your prescription quickly using the details on the pharmacy label.

🌱 Can You Smoke Medical Cannabis

No. Smoking medical cannabis is not recommended or supported by doctors, pharmacists or UK regulators. Vaporisation is the medically approved route for dried flower because it avoids combustion. Smoking can also lead to misunderstandings with the public.

You can legally possess your medication, but smoking it is not considered a medical route of administration and can create avoidable complications.

🌱 Medical Cannabis vs CBD vs Street Cannabis

These three things are not the same.

Medical cannabis
A regulated CBPM prescribed by a specialist doctor. Lab tested for potency, purity and safety.

CBD products
Over the counter items that must contain only small trace amounts of controlled cannabinoids. Not replacements for medical cannabis.

Illegal cannabis
Unregulated, untested and still illegal to possess, supply or grow. Not the same as a legal prescription and not produced under medical standards.

🌱 Common Myths About UK Medical Cannabis

Myth 1. GPs can prescribe medical cannabis
They cannot. Only specialists can.

Myth 2. CBD oil is the same as medical cannabis
CBD products contain only tiny levels of controlled cannabinoids and are not comparable.

Myth 3. A prescription gives you the right to smoke cannabis
You can possess your medicine, but you must still follow UK laws around where you can and cannot smoke.

Myth 4. Getting a prescription is easy
Clinics have strict eligibility requirements and require medical evidence.

🌱 Is Medical Cannabis Safe

Medical cannabis is considered safe for most adults when used under medical supervision. Like any medication, it may cause short term effects such as dizziness, dry mouth or increased appetite, particularly during the early stages of treatment.

Clinics monitor patients carefully and adjust doses or product types when needed.

🌱 Why NHS Access Is Still Limited

Even though medical cannabis is legal, NHS access is rare because
• Clinical guidelines are very strict
• NHS trusts often do not fund treatment
• More large scale research is still required

For most people, private clinics remain the only realistic route for treatment.

🌱 Final Word for Patients

Medical cannabis is fully legal in the UK when it is prescribed by a specialist and obtained through a licensed pharmacy. If you are considering treatment, the safest and most reliable route is through a regulated clinic that follows all UK medical cannabis laws and standards.

Understanding the law helps you make confident, informed decisions as a patient. The UK system can be life changing when you know how it works and what is available.
