Cannabis drug cuts arthritis pain

A drug made from an extract of cannabis has helped to reduce the pain caused by rheumatoid arthritis.

The drug, Sativex, has been developed by GW Pharmaceuticals, which is assessing the medical benefits of cannabis under a UK government licence.

Tests of a spray form of the drug on 58 arthritis patients showed it helped reduce pain, and improve quality of sleep.

Few people showed signs of side effects, the company said.
