Thank you.
I just wanted to say that as we look at e-cigarettes containing nicotine, we know that some e-cigarettes or at least the electronic version can contain things other than nicotine. If you regulate e-cigarettes in the same way that you regulate tobacco products and cigarettes, what would you suggest in terms of regulation for ones that do not contain nicotine? How would you regulate those? Would you still put them under the same sorts of regulations as tobacco or e-cigarettes that have nicotine? What would you do with those?
