This is dishonesty in research.

The Rest of the Story

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?

I believe that such a modified, randomized clinical study is essential to add another line of evidence with which to evaluate the potential benefits of electronic cigarettes. Yes, there are limitations to RCTs, but it makes no sense to throw out the baby with the bath water.
