I have to admit that most smokers who start vaping do dual usage at the start, because it's a transition, just as when smokers start using a nicotine patch they also are able to continue smoking using the patch. It's the aspect that once you start to transition, you either become a vaper or—the other aspect—that if they do dual usage, most vapers will not smoke as much and will cut down on smoking quite a lot. This is taken from studies that we have seen.
Here again, if we can stop them from smoking a lot and maybe go to zero smoking, I think that should be supported.
