What this indicates is that this is not simply junk science. Rather, it is a deliberate attempt on the part of the investigators to misuse data. They are using these data to draw a conclusion about whether electronic cigarettes are effective in helping smokers quit, yet they are knowingly drawing upon data from smokers who are using e-cigarettes for other reasons, who may have simply tried an electronic cigarette once, and who most definitely were not using these products as part of a current quit attempt.

While Senator Rockefeller attacks the electronic cigarette companies for targeting kids with flavored products that he claims is going to addict and harm them, he is hiding from the public the truth:

Here, they find a correlation between e-cigarette use and higher and more sustained levels of smoking. But because this is a cross-sectional study, they cannot determine which came first. In other words, what is the direction of the causal relationship? Does the e-cigarette use precede, and cause, the smoking? Or does the smoking precede, and cause, the e-cigarette use?
