Actually, because we have a prototype of a system like this in Canada, for the most part, half the time a druggist stopped us because the person had already stopped it, and they come to their practitioner and say that it isn't working, that they had a big rash, or had uncontrolled nausea, and so they took themselves off it. So the physician dutifully records it so that they know that they shouldn't be prescribing that drug yet.
