When it comes to trade, I think what's most implicated by the treaties is the trade in medicines in the sense that it was mentioned that these treaties do govern not only the illegal use of narcotics but also their medical use. From that perspective that is one advantage of the treaties as they exist, and the treaties do regulate the trade of medicines quite well.
I'd be happy to look into this and happy to get back to the committee about other treaties, but when we talk about these treaties and trade often what we're talking about is trade in medicines.
