An unnamed Melbourne-based doctor at the Royal Melbourne Hospital's neurology department stated that marijuana might be effective in easing the symptoms and pain of MS for sufferers.

British company GW Pharmaceuticals, which specialises in developing cannabis-based prescription medicines, manufactures the spray called Sativex, which the doctor wants to push for trial.

Reports state that the doctor will soon seek permission from the state and federal to use the mouth spray.

According to a hospital spokesperson, "The prescribing medical practitioner is currently going through the process of applying for approval from the hospital's human research ethics committee.”

The company’s website also states that no evidence has till now been established that patients by using the spray would obtain a high such as those experienced by marijuana smokers.

However, there are side effects of Sativex like sleepiness, nausea, and dizziness.

In some countries for giving relief to pain among cancer patients suffering from rheumatoid arthritis and neuropathic pain this prescription is being administered already.
