Where cardiovascular risk is concerned, the harm may be in the stress on the cardiovascular system in the short run, but not necessarily in any degradation of the system in the long run. Where lungs are concerned, perhaps it is the other way around: that there is some long-term deterioration in lung function associated with long-term vape use. We do not know because, probably, we do not have enough longitudinal data for this purpose. Where cancer is concerned, particularly in so far as it may manifest from genetic mutations over time and damage to DNA, there are clearly toxic elements in those products, as there are in many products. There are many illegal products that have carcinogenic elements and properties within them. We need to know how much, over what time and in what respects. For the moment, we are in a position where we have a relative absence of evidence about this but, as we know, absence of evidence is not evidence of absence, so we need to get to a better position on that.
