A CANNABIS-based pain relieving drug will not be available on NHS to Oxfordshire's Multiple Sclerosis patients. There are 1,000 Multiple Sclerosis patients.

The disease of MS attacks the nervous system. A mouth spray known as Sativex, which consists of extracts of this drug, was given the approval for use in the last week. The NHS has declared that the spray would not be recommended on a routine basis.

Although, Cannabis is medically proven drug for the disease, but it is illegal. In a drug trial for 10 years, it was found that Sativex is effective in reducing the symptoms of MS.

Stevan Heads of Abingdon said, "It totally reduced my pain; I felt no pain at all when I was on it. It also reduced the spasms by about 90 to 95 per cent". He took the medicine for 10 years.

According to him, since the time he has left the medicine, his pain has aggravated.

Mouth spray, Sativex can be sprayed under the tongue for 12 times in a day. This drug costs NHS £125 per 10ml vial and on an average, it costs £11 a person, per day.

The drug is also found to decrease the insomnia in 40% people.
