Medical cannabis and the law

It’s perfectly normal to have questions about medical cannabis.

Here are answers to some common questions about legal rights and wrongs.

General

Medical cannabis has been legally available on prescription in the UK since 2018. Today, more than 200,000 people in the UK access medical cannabis treatment from clinics like Wellford.

Furthermore, under the Equality Act 2010, registered medical cannabis patients are protected against discrimination and must be treated in the same way as any other medical patient.

It’s perfectly legal to possess medical cannabis with a valid prescription.

You can prove you’re a medical cannabis patient by providing:

  • a copy of your prescription;
  • medication in its original packaging; and
  • valid ID.

In 2025, the National Police Chief’s Council advised police officers to assume that “people in possession of medicinal cannabis are patients until proven otherwise”.

It is still illegal to smoke medical cannabis in the UK.

You should always take medical cannabis as prescribed by your doctor.

You can vape medical cannabis using a special vaporiser. You can also take medical cannabis as a capsule, an oil, an edible pastille or apply it to the skin as a cream.

Ask your doctor about the best option for you.

As with any other prescription medicine, you can take medical cannabis in public and outside your home.

You should carry a copy of your prescription with you in case you need to show you’re taking medical cannabis.
