Travelling with Medical Cannabis: What You Need to Know About the Law

by Jacob Strzeszewski

Travelling with medical cannabis from the UK can feel overwhelming, but with the right preparation and documentation, it doesn’t have to be. In this guide, we break down how to travel safely and legally with your prescription, so you can feel confident every step of the way.

Can I Take My Medical Cannabis Abroad?

Yes, but there are rules to follow. If you’re leaving the UK, you need to be able to prove your medication is legally prescribed. This means carrying either a copy of your prescription or a letter from your clinic. It’s also important to keep your medication in its original packaging with the pharmacy label attached. That way, if you’re ever questioned, you have clear proof that it’s yours.

Do I Need a Medical Cannabis Card?

Nope! The UK doesn’t require a medical cannabis card. If you have your prescription and your medication is properly labelled, you’re good to go. Some patients like to carry additional documentation just in case, but it’s not essential.

How Do I Make Sure I’m Following the Rules?

Since every country has its own stance on medical cannabis, it’s always best to check ahead of time. Before you travel:

  • Look up the rules for your destination on their official government website.
  • If you’re unsure, contact the country’s embassy for confirmation.
  • If your destination requires extra paperwork, request a travel letter from your clinic (just make sure to do this within a week of departure!).

What Happens If My Destination Doesn’t Allow Medical Cannabis?

Some countries have very strict drug laws, and unfortunately, medical cannabis is still illegal in many places. If your destination doesn’t allow it, don’t risk travelling with your medication—it could lead to serious legal trouble, including fines or even prison time. Always double-check before packing. You can always check the travel restrictions for the country you’re visiting.

Cruises and International Waters

Cruise lines generally prohibit the possession and use of medical cannabis on board their ships. Regardless of your departure point or destination, bringing medical cannabis is not permitted. Violating these policies can lead to serious consequences, including removal from the cruise and involvement of law enforcement authorities.

Given these strict regulations, it’s advisable to consider alternative travel options if you rely on medical cannabis. Always consult with your chosen cruise line before traveling to understand their specific policies regarding medical cannabis.​

Connecting Flights and Layovers

Even a short layover can complicate travel with medical cannabis. Some transit countries enforce strict drug laws, even for passengers who don’t leave the airport. Here’s what to keep in mind:

  • Transit Country Laws – Some countries treat possession of medical cannabis as a criminal offence, even if you’re only passing through. Check with the embassy of each country where you have a layover to make sure you’re in the clear.
  • Security Screening – If you must pass through customs during your layover, you could be subject to local drug laws. Carry all necessary documentation, and when in doubt, consider re-routing your trip to avoid high-risk destinations.

Who Can I Ask for Help?

If you need more details:

  • For UK travel rules, you can email the Home Office at dflu.ie@homeoffice.gov.uk.
  • For country-specific laws, the best contact is the embassy of the country you’re visiting.
