Should 'unsales reps' be in every state, to try to cut down on the number of doctors coerced by drug companies?

In a David vs. Goliath battle, Pennsylvania is among a handful of states trying to counter the pharmaceutical industry's multibillion-dollar marketing and cut costs for prescription-aid programs for senior citizens, who are bombarded with "ask your doctor" advertising. State officials here say they are trying to ensure that patients get the most effective treatment. But driving the outreach is an effort to hold down expenses — in some cases by steering doctors to generics, in others by showing how lifestyle changes can sometimes be preferable to medication.
