It should be regulated in terms that the concentration of nicotine is well marked on the bottle. You've heard stories that people were selling e-liquid pretending that it contained 15 milligrams or 18 milligrams of nicotine, while as a matter of fact it was almost down to zero.
If we don't regulate it, we're going to have an accident one of these days, because somebody is going to put some terrible stuff in it and put it on the market. It needs to be regulated; the smokers need to know that they are buying a good-quality product. Again, we'll have to keep pace with the new hardware of the electronic cigarette itself to make sure that it's functioning properly and also that people are using it properly. The manufacturing of the electronic cigarette is important, to ensure that it's good stuff and that the e-liquid sold in the shops is also good stuff.
