I think we should think again about some of the language that the Member has used: you said that e-cigarettes are significantly less harmful than tobacco. That does not mean that they're not, themselves, harmful; it's about the balance in harm. And it's also about a recognition that we don't always understand what goes into an e-cigarette. We had this debate in this term with the public health Bill, and in the last term as well there was a change of position about our ability to regulate this area. There's something about being able to regulate the products, because, actually, if you don't know what's in an e-cigarette, that's rather difficult, and I think there's something there for us to continue to consider. The Government has no intention of promoting e-cigarettes. There are choices for people to make themselves, as citizens of the country. I think that we have to, as I said earlier, continue to be led by evidence on what we could and should do, what we could and should promote.
