I thank my hon. Friend for providing such a powerful case. I could not agree with him more. To my way of thinking, banning smoking would do me, but we probably cannot go that far. Does he agree that the broader point of health economics is also important? Lung cancer is not the only issue. There is also emphysema, pulmonary disease and so on. If we sort out the tobacco issue, we could make much broader savings across the health service.
