I don't know the exact number, but I can tell you all the things that go on to encourage and motivate. The fact that we have participation is really good, from my perspective, from a correctional perspective. Sometimes inmates don't like to acknowledge that there is an addictive property, but they're taking those steps.
Much goes on, as I mentioned, with our health care department, from the nurses continuing to promote health care from that perspective.
We also have peer support groups in a number of institutions. We have inmates who will speak with inmates who use, and who basically look at it from their perspective and encourage in that way.
On your question about doing more, I think we just continue what we're doing to motivate, encourage, and persuade inmates who have these properties. Again, if we become aware through urinalysis testing or through other activities that inmates are participating and are not part of that program, referrals of those inmates will be made through the case management process. So, much is done to ensure that participation.
