Medical cannabis: my rights
I am a lawful medical cannabis patient in the UK.
My proof is my medicine in its original packaging with the dispensing label. This card is not proof of a prescription.
If police stop me
- I stay calm and say I am a prescribed patient.
- I show my medicine in its original, labelled packaging.
- National police guidance (made public January 2026) asks officers to treat patients first and to check with my clinic.
- There is no legal requirement to carry a prescriber letter, but it helps.
If I am driving
- I have a medical defence if my medicine is prescribed, taken as directed, and I am not impaired.
- I never drive if impaired. That is a separate offence the defence does not cover.
- I do not refuse a police sample. Refusing is a separate offence.
- I carry my prescription and packaging, and I tell the DVLA if my condition or medicine affects my driving.
