How is it that anti-smoking advocates and health groups, including the state's physicians, could possibly oppose a simple ban on the sale of e-cigarettes to minors?

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?

With hundreds of electronic cigarettes out there, I hear outlandish claims all the time and most of them have been nothing more than just sales pitches.
