Travelling with Prescription Cannabis: UK and International Rules
If you’re prescribed medical cannabis in the UK, you may be wondering whether you can take your medication with you when you travel. The answer is: it’s possible, but it requires preparation. Cannabis is still a controlled substance worldwide, and every country even every state or region has its own laws.
Here’s what you need to know to travel safely and legally with your prescription.
Travelling Within the UK
Carrying your prescription cannabis within England, Scotland, Wales, and Northern Ireland is legal if you:
Keep your medication in its original pharmacy packaging
Carry a copy of your prescription and dispensing label
Travel with only what you need for your journey or stay
Follow any additional guidance from your doctor about storage and use
Security checks at airports or ports may involve additional screening. Having clear documentation speeds up this process.
Travelling Abroad
International travel is where it gets complicated. While cannabis-based medicines are legal in the UK, many countries do not allow you to bring them in, even with a prescription.
Key Points:
Check every country’s rules well in advance, including those you transit through.
Some countries have strict zero-tolerance laws, meaning possession is a criminal offence, even if your medicine is prescribed.
Others may allow cannabis-derived medicines but require import permits or medical declarations.
Examples:
EU countries: Rules vary. Some allow travel with prescriptions, others require additional permits.
North America: Canada has a regulated system, but travellers cannot cross US borders with cannabis — even between states where it’s legal.
Asia & the Middle East: Most countries have strict bans, and possession can result in severe penalties.
Getting a Schengen Certificate
If travelling within Europe, some countries recognise a Schengen Certificate (also known as a Schengen Declaration). This:
Certifies your prescription is legal in your home country
Is issued by the Home Office for controlled medications
Typically lasts 30 days and is country-specific
Keltoi can guide you on how to apply for this if you’re eligible.

When Travelling Is Not Recommended
If your destination has strict cannabis laws or zero-tolerance policies, it may not be safe to travel with your prescription. In these cases:
Speak to your clinician about alternative medications for your trip.
Consider using travel as a planned treatment break, if appropriate.
