First, in response to some of the questions and concerns posed by Chlöe Swarbrick, I do wish to provide real confidence to the committee that this legislation has been developed very carefully, and it most certainly doesn't arise out of a moral panic about this issue. I would just put to the attention of the committee a number of supporting facts that sit behind my saying that. The first is that the evidence is on the table that there is a real problem to be solved here. Now, moral panics classically are situations where there isn't actually a real problem to be solved—they're situations in which people in legislatures and communities whip themselves up into a lather about something they don't like, but perhaps something that isn't actually a problem. The evidence on the table is very clear in New Zealand, that we have a problem. We have a lot of people every year who die on our roads who have these substances in their system. And while at that unfortunate point it's not always possible to draw a direct link between the consumption of that substance and the accident that has been caused, there is a very strong and reasonable supposition that in many of those cases there is a strong link. And that's not to get into the serious injuries that are also caused.
