Would other factors be included in causing some of the extreme symptoms that we've seen and read about? For instance, use of other not prescribed drugs? We've heard of that happening. We're trying to draw conclusions from very serious incidents. Especially in the past, there have been references to the Canadian Airborne Regiment and so on. How can we say, for sure, that the behaviours were specifically the result of one thing when they could be the result of many things?
