The Rest of the Story

The article reports the results of a cross-sectional sample of adolescents interviewed in 2011 and 2012 in the National Youth Tobacco Survey. Youths were asked to report their smoking status as well as their e-cigarette use, both any use and current use (at least once in the past month).

The point is that there was no way for the cigarette companies to comply with the law, other than to change the banned descriptors to a new term. And no matter what term they chose, consumers would have figured out which brand was which. Moreover, the law did not specify or imply that the companies were prohibited from informing consumers which brand was which.

The truth is that there are major advantages and disadvantages of both surveys and clinical trials to examine the potential benefits of electronic cigarettes. Both types of study designs have inherent biases which can produce results that are more "favorable" or "unfavorable." This is why the methodology of published research needs to be examined so carefully. It is not so simple as to dismiss RCT evidence and accept survey evidence. One needs to consider the strengths and limitations inherent in both approaches. And at the end of the day, the only defensible approach, I believe, is that both types of studies are necessary, and we must carefully interpret and synthesize the findings from studies of multiple designs, using the totality of the evidence to make final judgments about the benefits of electronic cigarettes.
