I raise that because simply prohibiting the purchase of something doesn't mean it's not going to be used, and we do risk potentially romanticising the product by making it out of their reach and having the opposite effect. Now, I don't think that's as material of a concern as I have with the low-nicotine cigarettes. But I do think the Health Committee needs to look really deeply, as it tried to do with the vaping products and, actually, we didn't get a very good response. So I think we've really got to keep the ministry's feet to the flames on this one. I applaud the ideas, I applaud the novel approach to breaking this cycle of nicotine dependency, but we've got to go in with as much of an evidence base as we can, and particularly if there's a risk that we could do more harm than good. But I wish the select committee all the best in that; I'll be watching it very, very closely, because I'd really like it to succeed.
