Know the law. Stand your ground.
If you've been refused entry or asked to leave for using your prescribed medicine, you have rights. Here is the UK law in plain English — with the sources — so you, and anyone who challenges you, can respond calmly and on the facts.
Your medicine is legal
Since 1 November 2018, cannabis-based medicines have been Schedule 2 controlled drugs that specialists may prescribe. A valid prescription is full legal authority to possess and use your medicine. Misuse of Drugs (Amendments) Regs 2018
Proof of lawful possession
The dispensing label on your original pharmacy packaging, plus photo ID, is sufficient proof. You do not have to disclose your medical condition. A private "cannabis card" is not required and carries no legal weight. NPCC / APCDLO guidance, 2024
Vapour is not smoke
Smoke-free laws apply only to smoking by combustion. The Home Office has confirmed that vaporising devices fall outside smoke-free legislation. A "no vaping" rule is a venue's private policy, not the law. Health Act 2006 · Home Office FOI 2023/05814
Protection from discrimination
Where your condition is a disability, venues, employers and services have a duty to consider reasonable adjustments. Allowing e-cigarettes while banning a medical vaporiser can amount to discrimination. Equality Act 2010
Driving
A statutory medical defence protects prescribed patients from the blood-THC limit offence if the medicine is taken as directed and driving is not impaired. It does not cover impaired driving. If you've medicated, don't drive. Road Traffic Act 1988 s.5A & s.4
If you're stopped by police
Stay calm. Show your dispensing label and ID. UK police now follow national guidance to treat patients as "patients first, suspects second." You can ask the officer to consult their Controlled Drug Liaison Officer (CDLO). NPCC / APCDLO guidance, Nov 2024
