The quick answer on regulation is Clive Bates' submission, that you have, because he gives a very good overview of what would be necessary. In short, we want to make sure these products are not placed at a disadvantage to cigarettes. We want the less hazardous products to be the more available products.
We also want to ensure that our fear about unintended consequences, such as children getting access to these.... Keep in mind that 80% of smokers say, “I wish I didn't smoke”. Where are kids getting their cigarettes? They're getting their cigarettes from family, people who don't want to smoke. If we could get them off smoking, we would get rid of a lot of the access that gets kids started. There's huge potential upside on this. We just need to be sensible on the regulation and avoid things like “medicinalizing” it so that cigarettes are given an advantage in the marketplace.
