We agree. As the American Heart Association, the WHO, and others have said, there is a need for a regulatory regime that is sufficiently broad to deal with the scientific uncertainties that—you're absolutely right—will evolve over time. You want a regulatory regime that is broad enough and flexible enough to be responsive to the emerging science and our emerging understanding of the harms and the benefits, and one that protects youth. Youth protection is definitely foremost in our minds and certainly was foremost in the minds of these various international studies that you've mentioned.
Related to that, we certainly think it's important to have a regime that would protect the tobacco control gains we have made in this country. Canada remains a world leader. Something we certainly want to avoid is, through electronic cigarettes, seeing our gains in tobacco control erode.
I certainly agree with what you say, wholeheartedly.
