A pain-relieving cannabis spray pioneered in Norfolk could be available on prescription after a successful trial.

The James Paget Hospital at Gorleston was the first in England to offer the spray to patients.

Beverley Lowe, who has multiple sclerosis (MS), told BBC Look East that the spray has proved to be effective - and has also kept her from breaking the law.

She said: "The pain was getting to the point where I couldn't stand it anymore, and if it hadn't been for this spray, then yes, I would be smoking it illegally."

Dr William Nottcutt, who runs the hospital's pain relief clinic, said: "A couple of patients said to us that they've had the best night's sleep for ten years (using the spray).

"Now, that's amazing."

Dr Nottcutt said it was hoped that the Department of Health would licence the cannabis spray after hearing positive testimonials from patients.

The spray has been tested on people with MS, spinal cord injuries, nerve damage, and pain from cancer.

The trial was carried out by GW Pharmaceuticals, the company licensed by the Home Office to research and develop prescription cannabis-based medicines.
