If I could, I would like to add something quickly. We don't know whether experimentation with e-cigarettes will lead more youth to go on to use cigarettes. We don't know whether it will introduce them to nicotine, which will then lead them to transition to the most effective nicotine delivery device, the cigarette, or whether they'll be more likely to become long-term e-cigarette users. It's still too early, and we don't have very many studies on this correlation at this point.
