The government is expected to sign new laws today paving the way for cannabis-based medicines to become legal in Ireland.

The oral spray, called 'Sativex', has been launched in 11 countries (including the UK, Spain, Italy and Germany) and approved in a further 13.

The legislation is likely to be signed by Minister of State Alex White later today.

It is proven to ease symptoms and significantly improve the quality of life of people suffering from illnesses like multiple sclerosis.

It is also used in palliative care for patients who are in severe pain.

The company has confirmed it submitted an application for approval by Irish authorities.

Tom Curran - whose partner Marie Fleming died of MS - has been campaigning for years to have the laws changed.

He says although he knew it was illegal, he grew cannabis for Marie so she would get some relief.

He told Newstalk Breakfast this is not about drugs, but about helping patients.
