Insofar as level, I really think we're at a very early stage to be able to say it should be definitively this level or that level. But what I did say, and which I will repeat, is we most certainly need legislative and regulatory framework in which those levels could be specified based on careful research and evaluation to be done in the future.
With respect to the products that are currently available without nicotine in them, I really see no benefit of those at all. I don't see any reason that we should have those in the marketplace. Something is being inhaled. It can't replace nicotine because it doesn't have nicotine in it. But once again, I would defer to further research, careful research, by regulators and researchers on that.
