Yes.
Dr. Nevin suggests that Somalia forward is the era he's looking at, at least with respect to American veterans. I'm not sure if that would apply directly to Canada or not, but it sounds about right. If we started from 1990 forward...? Honestly, I don't know when the drug was released. I don't know when it started getting used by veterans, or soldiers at the time. There are a lot of question marks in my own mind certainly.
