There's a lot of polysubstance abuse.
For instance, it may be that the person is receiving a prescription from their family physician but in addition on Saturday night they did a line of cocaine. If you're asking for only the people who have their prescription abuse, there is a significant number. I can get back to you with what that exact number is. I would guesstimate that one-third of the people have issues of pain and don't want to admit any addiction issues. We know that if they were asked by their family physicians to stop cold turkey, they would be going through withdrawal, and that's part of the definition of the addiction.
What we try to do, because they don't want to accept that they have any addictions—it's just their family doctor who is writing the prescription for them, so how can they be addicted—is to reduce the pain. Our treatments are multitudinous, and there's a chart where it shows all of the different things we do. Then the physicians can actually titrate them to a lower, more acceptable level. In some cases people totally get off their medications. I would say probably one-third of the patients who come to see us have an issue with just the use or overuse of their medication from the family physician, without buying any street drugs or anything else.
