What we have to be very careful about is this: we do not have the longitudinal data that we do in relation to, for example, tobacco use. We will acquire that. We may have 10 years’ worth of data; one would ideally want at least 20 years’ worth. To some extent, as we can see from the study that was published several years ago in America on e-cigarettes, we know in relation to lung condition and cardiovascular risk, for example, that the use of vapes is clearly much less harmful than smoking, but it is not without harm. We have had that discussion. The question is: how much harm and over what period?
