Also, one thing I do want to comment on is the real lost opportunity to understand and to enact the issue of vaping with young people. I've got my good friend and colleague the Hon Nicky Wagner, who's spent a lot of time on the vaping issue, put a very good bill on vaping regulations, but, unfortunately, it wasn't picked up by this Government, and now we're in a select committee process with a vaping regulation bill that—well, it'll be interesting. But, let me say, if you're a betting person, I'm not sure you'd say it would be coming out before the end of the 51st Parliament. And we missed a real opportunity to look at vaping in this bill, because, of course, we do say that vaping is less harmful than smoking—some academics would say it's 95 percent less harmful than smoking—but, by definition, it does carry some harm, and this bill won't pick up those adults that are vaping in their vehicles, whether that be stationary or moving, and affecting the young people. Second-hand smoke is serious and it will have, as Dr Shane Reti said, some very serious physical impacts, but we also know young people who have grown up who have been constrained in a vehicle and forced to breathe second-hand smoke also developed psychological issues as a result of that. And, at times, that psychological impact can be as harmful as the physical impacts as well. It would be my assessment that vaping could be equally as harmful—quite often we see those big clouds of vaping smoke coming out of car windows, and you can only imagine, if those windows were rolled up, the amount of vaping that's going on in those cars.
