Just to add to that as well, I take your point, and we don't want to throw the baby out with the bathwater, so to speak.
There are some good nicotine replacement therapies today. Perhaps they're not as effective as we would like them to be. Because you can hold a cigarette and it's going to allow people to feel as if they're still engaging in the habit, etc., that could be useful in smoking cessation. That's why a number of groups are interested in doing more research on e-cigarettes, to see if, in fact, they could be useful. There is some potential there, so we don't want to dismiss that.
