There are a couple of things we do. If the individual had been on a self-administering regime, we would do an assessment of whether he or she could be trusted with certain quantities of medication. If we find a prisoner has been hoarding medication, we would probably put that person back on what's called a direct observation approach. This means that the prisoner would have to take the medication in front of a staff member, more than likely one of our nurses, and then go through a routine to demonstrate that the medication had been swallowed.
We also have the ability under the legislation to do drug testing through urinalysis, and we've increased the number of urinalyses by over 20% since last year. We will use that on a random basis. Also, if we suspect individuals, under certain elements within our legislation, we can have them tested as well.
