It's also worth noting—and this is a conversation that I had with the Minister—that tobacco can be grown naturally, in the same way that the likes of cannabis can be. So there are some important considerations also to be made about what occurs in those kinds of instances, were it the case that this hypothetical future smoke-free generation were to stumble upon some tobacco growing out there in the wild. Thirdly, the Greens continue to have concerns—as, interestingly, I've heard from some members of the Opposition as well—about some of the quantification that has or hasn't been done around the black-market implications. Interestingly enough, these are debates that we also had on Budget night, when I was asking the Minister, then of Customs, about the implications of increasing tobacco excise tax on particularly the need to then put all the more money into enforcement, and where that balance should best be struck and what those implications are for, again, that evidence-based policy that we all seem so attuned to wanting in this debate.
