Well, they still have to operate within the law. The law does permit the development, licensing and marketing of medicines, including those containing controlled drugs, such as cannabis. I have used the example of Sativex, which I believe provides relief to patients with MS. My hon. Friend talks about lots of other cases like this one. It is worth noting, however, that in the case of Alfie Dingley, I think only nine other children in the world suffer from the same type of epilepsy as he does. That is why I have undertaken to explore every option on his behalf. I make it quite clear that the Home Office and the Government are keeping this area under review, because this is fast moving. The House will of course have the chance to debate it along with the private Member’s Bill.
