I know we heard from the United Kingdom yesterday. There was a strong emphasis by the public health officer who presented to us that they've decided that it's a very important tool to use in helping people to quit. So they've gone ahead and decided to let it be used. At the same time they're trying to do some of that research, as you say.
In Poland some research showed that people who never smoked before are beginning to use e-cigarettes. It's the only one of the studies that showed this was happening. I think the other ones didn't show that. I think it would be really important to look at that issue, because if you're going to decide you want to use it to help people quit, that's one good thing. But if it's going to be encouraging more people to use nicotine—not that nicotine in itself is terribly harmful, but to be using some sort of vapour with who knows what toxic things are going to come out, which only time can tell—it would prove then that you've created a new type of method of getting hooked on nicotine and on whatever the side-effects are of that.
How then would you go about getting rid of e-cigarettes if they prove to be that way, having allowed their use to become normal? It would be difficult to shut that door once you've opened it.
