Thank you very much, Chairperson.
First of all, it's been a very interesting discussion to hear your perspectives.
I'd just like to go back to Professor Britton and speak about the experience in the U.K. I do think there's a lot of mythology around addiction. The stuff that I've read argues that probably the most common and one of the most powerful addictions, which you alluded to, is caffeine. In fact withdrawal from caffeine is very, very severe, as anyone who has tried it will know. Yet it's so culturally accepted in our society that we barely talk about it. So there is relativity in this discussion.
I'm very curious to know about the British experience in terms of how the debate went politically. You speak about harm reduction, risk minimization, and how less is better than more; e-cigarettes are better than people smoking outright combustible cigarettes and so on. Yet in the debate we have here, there's a great fear about a harm reduction approach. It has almost become a bad terminology to use. We keep coming back to this notion that it's only zero tolerance and prohibition, which to my mind means chaos, and that it's somehow a better approach. I don't subscribe to that myself.
I just wonder about how the debate went politically. You talked about two different governments that adopted this approach. What was the debate like in the U.K. around e-cigarettes and from a harm reduction point of view?
