I am grateful to my hon. Friend and congratulate him on obtaining a debate on this very important subject. It has been said that beta interferon, which people are pleading to have available on prescription in this country for sufferers from multiple sclerosis, will not be available until it has been through trials. People find that they can get relief from some of the most dangerous and soul-destroying tremors of MS by using cannabis. If the Government are determined to trial beta interferon and probably delay its use for another decade, they should hear this plea for the use of cannabis as a prescribed drug for MS.
