One of the greatest concerns with this is that a lot of these precursor chemicals are used in normal, legal commercial enterprises. It's very hard to stop some of this, because a lot of what's being used can be found in legal products.
I deeply share this concern. This is one of the things being worked on very actively now. We have a conversation with our American counterparts about how we can do this together. I think taking a North American approach and working collaboratively across North America makes full and complete sense.
