Some of those outstanding concerns specifically include, firstly, the untested proposal, which a number of others have put on the table in the debate this evening, of substantially restricting the amount of nicotine in cigarettes. It's untested. It's untested, from my understanding, anywhere and, therefore, it is going to need some serious, robust kicking around. Secondly, we do have some concerns around the imposition of this so-called "smoke-free generation" ban, which, whilst absolutely innovative and therefore important, does, effectively, make tobacco criminally prohibited for a portion of our population and eventually, were this to come into effect, for the entire population moving forward. Of course, one of the important components of drug-harm reduction as an approach is to note that there are alternatives. So here we are also looking at other methods of administering nicotine—that being particularly through vaping, and, of course, there is a really important discussion to be had there, too.
