I use to work in doctors offices years ago...they had small closets full of meds given to them as samples by pharma reps...they come in, bring lunch for the staff, handouts on new meds (goodies) and the docs just hand them out to patients & say here try this....they don't have any time to research any of these drugs, they just go by what the reps tell them. Some reps don't even have medical degrees, actually most don't, they usually have English or business degrees. I saw it happen daily/weekly. One doc I worked for was so busy his office was a complete mess with papers & charts strewn all over, they spend a minimum of 15 minutes with you in an office visit so they can see as many patients as possible due to insurance, I finally quit.
