I'm not sure if you've heard this statement before, but it was repeated ad naseum during many of my nursing classes: giving patients opioids rarely leads to addiction - less than 1%. This claim was usually made as a seemless introduction to a statement about how pain is the 5th vital sign, should always be treated, and nurses should have no fear about giving narcotics.
While treating pain is important, it seems that dispensing narcotics with the belief that the rate of addiction is less than 1% might not be accurate. Here is a link to the original article that numerous people have cited when repeating this claim:

Anyone find any problems with this "study"?
