No, it's exactly right. There are two classes of people seeking pain medication: those who need it, and those who do not need it. Now, we can argue over who exactly needs the medication, but it is not right to suggest the second category does not exist.
Right, there might be two groups ("people who need meds" and "people who don't need meds"), but the overlap of those with "people in real pain" and "people faking it" is poor. It's that simplistic, and incorrect, mapping that I'm objecting to.
