Travelling With Your Prescription
What the rules say
You may carry your prescribed medical cannabis to Spain provided it has been prescribed by a licensed doctor, purchased legally in the United Kingdom, is for your own personal use, and the quantity is limited to the rational dosage required for your trip. The maximum permitted quantity is equivalent to a 3-month supply.
If your treatment involves a substance under international narcotic or psychotropic control — which applies to most cannabis-based medicines (CBPMs) — you must obtain prior authorisation from the Spanish Medicines Agency (AEMPS) before you travel. This is done by completing the application below and emailing it with supporting colour PDF documents to estupefacientes@aemps.es.
- Original pharmacy packaging with dispensing label — never decant into another container
- A copy of your UK prescription from your prescribing clinic
- A signed and stamped letter from your prescriber detailing the medicine, dose, and medical necessity
- AEMPS prior authorisation confirmation (emailed back to you once approved)

- Vaporisers must be in hand luggage; batteries may have airline-specific restrictions
- Declare your medication proactively at customs — do not wait to be asked
