My Lords, does the noble Earl agree that the noble Viscount is perhaps guilty of a little bit of journalistic licence on this issue? The Cochrane review undoubtedly produces encouraging results, but its research contains a big “but”, in that it cautions that only two studies, covering just over 600 smokers, were reflected in the review. The Cochrane review says that we should await the outcome of further studies. Does the noble Earl agree, and can he inform the House when we are likely to see the outcome of those further studies?
