Jackie Bird reports as a Plymouth professor reveals the results of an eight year national study into Multiple Sclerosis at a national conference today. The project found that cannabis use, shown to ease the symptoms of MS, didn't actually slow the progress of the disease down.
Scientists at Plymouth University say cannabis has no effect in halting progressive multiple sclerosis. But they say it may have some benefit for people with less serious MS.
Experts studied 500 people with MS over an eight-year period. Some were given capsules containing the active ingredient in cannabis, while others were given placebos.
