I'll speak generally in terms of the issue of public health. The regulations and the addressment of what are appropriate standards I think go through a fairly important assessment in terms of risk. One of the challenges we have scientifically is we're now able to measure things to such a small level that we really have no comprehension of the benefits. There's always a trade-off. Virtually everything at the right dose is useful and at the wrong dose is harmful. The regulators are in Health Canada on that, yes.
