I think nanotechnology is one of those things that is still very cutting-edge in terms of where they are at. There's a lot of uncertainty associated with those materials.
I think the first thing we have to do is to better educate the public about what these materials are; what their safety profile is; what we do as industry to ensure that these products are safe, although innovative; and that industry is able to deliver innovative efficacy and create a difference as these innovative products move forward.
As with anything, it's really important to make sure that the consumer understands that these products are regulated, that they are well studied, that they have risk assessments done to ensure that they're safe, that they can be used safely, and that they do not present a risk to Canadians.
