What I said earlier—I think what I said and maybe I didn't say clearly—was that as people age, the source of their drug is more likely to be their prescription. Younger people are more likely to get their drugs from the street, and as you get older, you're more likely to get it from your prescription.
That being said, you're absolutely correct that from what we see and again—we only see the very end of the downstream as the chief has referred to—it is a problem in the elderly, either intentional or accidental drug toxicity.
Is the answer in education? I think probably it is. Again, it's physician education because we know that poly-pharmacy and the inappropriate use of opiates and other psychoactive drugs in the elderly is a problem. We see it regularly. Also it's education for patients to make sure they fully understand the appropriate use of the medication, that if one is good, five must be better doesn't apply when you're on sustained-release oxycodone, for example. If you're on a fentanyl patch, you really do have to take the old one off before you put the new one on. It's not an uncommon thing for us to see someone with five, and then we have to sort out if they simply did not understand to take the old ones off, or if they were actually intending to do that.
Yes, it is a problem, and yes, I think education probably is the way to go in that particular issue.
