Today, I discuss the reasons why hiding a conflict of interest like this is problematic.

1. Between 2003 and 2008, one of the authors performed consultation services for R.J. Reynolds and Lorillard and conducted research at his medical school which was funded by R.J. Reynolds, Brown & Williamson, and Liggett. The total annual amount of his consulting payments from Big Tobacco was as high as $40,000. While the amount of grant funding received from tobacco companies is not clear, one of the anti-smoking groups has documented that the level of funding in 2005 was $400,000 and in 2004 was $1 million.

3. Tobacco companies are promoting electronic cigarettes as being safe.

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?

This is dishonesty in research.
