A study published on Monday in the medical journal JAMA Internal Medicine indicates that even a small meal offered by a drug company may influence a doctor's prescribing behavior.  Doctors are not the only human beings that can be influenced by money.  Researchers, politicians, journalists/media, and maybe every organization or individual can be influenced by money or other forms of benefits/incentives offered by any organizations or individuals. 

Here is a NPR report on the study.   Even A Small Meal For A Doctor Can Tip The Balance For A Brand-Name Drug.  The study was published here.

Here is a website where you can check out how much money drug companies spent on your doctors.
