Those are the three operating arms and, as we go into select committee, I want to just identify some of the pros and cons as I see them here now. First of all: reducing the retail outlets, currently between 5,000 to 8,000. On the positive side, it has a moderate impact, looking at the modelling. It reduces initiation and maintenance and may have a significant impact in low socio-economic areas. On the con side, or the downside, if you like, certainly that black market risk has to be considered. I didn't see too much modelling or commentary in the Government's documents. How do you monitor low nicotine levels? That's an issue and this will clearly affect dairy owners as well.
