Why is the CDC unable to tell the truth? Why can't the agency even issue a statement that is internally consistent on this issue? Why is the CDC ignoring the wealth of evidence that it admits exists, which shows that many ex-smokers have used electronic cigarettes effectively as a smoking cessation aid?

Anecdotes are in fact data. Of course, what you do with that data and how you interpret it is affected by the nature of how the data were obtained. But anecdotes are data. Remember, the connection between smoking and lung cancer itself was first uncovered by a case series. Physicians started to note multiple cases of lung cancer - which was very rare at the time - all occurring in smokers. While these patients could be called "anecdotes," they were also people who provided very real and important data that led to the discovery that smoking causes lung cancer. That connection would not have been found had these "anecdotes" been dismissed.
