Thank you very much.
Those were very interesting presentations by everyone.
I know that what you are specifically dealing with as part of the team is the supply side, but from my knowledge as a physician and my understanding of these issues over the years, you can't only deal with supply side at any one point in time. You have to look at why the demand; the demand side is something you have to look at.
I would like to reiterate Mr. Hawn's request for short, crisp answers. I'll try to ask short, crisp questions.
Mr. Head, you said that 80% of offenders who came in were addicted in some way, or were taking medication of some kind, either prescription or illicit. I also note you said that after 20 years of doing this, this statistic has remained constant. Do you look at evidence-based...? I mean, if some statistic remains constant over 20 years, is there an opportunity to look at whether or not this is the right procedure?
