So two things: 1) This person is easy enough to find but I'm going to be vague here and not mention a name / company / area within an industry. 2) What the company does isn't legal in my state, so I have zero experience on either end of the physician office/patient equation. With those in mind...
I strongly question whether, in the course of providing management at this company (a company where neither this employee [nor the company itself] represents any drug manufacturer) that sampling is even a thing. This company doesn't detail drugs or rep a product -- I'm clarifying that this position isn't management level pharmaceutical sales. In my mind (again, not legal here, so my familiarity is low), sampling in this industry would be the equivalent of a Walgreens pharmacist sampling drugs to a doctor. (In nursing, we would call that diverting drugs. Not sure what they call it in pharmacy, but I believe they call it diverting drugs.
.)
So I just don't think this is a useful connection --> Someone Lori and Chad
may or may not have met,
may or may not have access to some drugs that
may or may not have been useful in....doing something.. and this person
may or may not have diverted those drugs to Lori or Chad. That seems like a lot of hassle for the kind of people who don't know better than to take their cell phones with them to crime scenes.
Sedatives would have been
easy for Lori to access after a truthful conversation with one of JJ's physicians. (And yes, I know she lies when the truth would have sufficed.)
