Unfortunately, it does not appear that these investigators are truly interested in whether e-cigarettes help many smokers quit or not. Instead, I believe that these researchers have a pre-determined conclusion that e-cigarettes are ineffective and that they are trying to manufacture results that support their pre-determined conclusion.

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.
