To respond further to the question, the Canadian Forces, the department, has put a new program in place composed of three parts. It has been announced in Canadian Forces and actually been made public.
The first is that we conduct safety sensitive testing of soldiers, sailors, airmen, and airwomen going into a theatre of operations. This is not just Afghanistan but into a theatre of operations. Clearly, if it is found that there are issues, they are removed. It has been done. We have removed individuals. The leadership has removed them--not doctors, but the leadership--for failing to meet the bar that we require individuals to meet in order to be safe and to be able to do what they need to do in combat.
Secondly, we've just begun blind testing across the Canadian Forces, randomly going across the Canadian Forces to draw some data.
Where we are moving in the future, in one year we'll be...to do testing as we see fit across the Canadian Forces, to additionally build on the policy and to address the issue that you raise.
