In an published in the Milwaukee Journal-Sentinel, professor of epidemiology Dr. Ruth Etzel - formerly with the World Health Organization - called for a ban on electronic cigarette advertising. However, she made no similar call for a ban on tobacco cigarette advertising.

These flaws are also noted by Dr. Robert West, director of tobacco research at University College London, who that: "the study was not able to assess whether or not for cancer patients who smoke using an e-cigarette to try and quit is beneficial "because the sample could consist of e-cigarette users who had already failed in a quit attempt, so all those who would have succeeded already would be ruled out"."

The Truth: Electronic cigarettes do not contain or deliver tobacco.

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.
