Sure, I'll speak a bit, and I'll ask Mr. McLauchlan to comment as well from what he sees on a day-to-day basis in the institution.
From our perspective, the issue of drugs or any contraband is part of the underground economy, and when you have inmates who are making a demand, and you have others who can supply that, this underground economy takes on a very significant nature in an incarcerated environment.
What we see happening at times are issues of muscling: individuals being pressured to bring things in, or to carry things between areas or between people. So individuals feel that their personal safety is at risk.
For us, the whole issue of tackling drugs in the institution is as much about creating a safe environment, because if inmates do not feel safe coming out of their cells, they're not going to come out of their cells to go to recreation, but they're also not going to come out of their cells to go to programs, and I need them to go to programs. Canadians need them to go to programs in order to return to the community as law-abiding citizens. So as long as they feel that their personal safety is at risk, or that their family members may be at risk and being pressured outside, then that has a potential negative impact on delivering good, rehabilitative programming.
If you don't mind, I'll invite Mr. McLauchlan to add his observations.
