Contrary to the assertion of the authors of this paper, simply being aware that the information one provides to Facebook may be used for research purposes does not constitute informed consent. The fact that users agreed to a Data Use Policy which notes that information may be used for research purposes does not, as the authors state, "[constitute] informed consent for this research."

But beyond the issue of medical or public health malpractice, I am most concerned about the simple principle of honesty. As medical and health professionals, our very first obligation is to be truthful with our patients and with the public. The information being provided by this respiratory therapist is untruthful. It is simply not the case that smoking may be less hazardous than vaping. There is no credible scientific debate about that issue in the year 2014.

And importantly, the same thing is being said today, in some hospitals, about smokers. A number of hospitals refuse to hire smokers not merely to reduce health care costs, but because they don't want their patients to have to even "see" a smoker.

One of the main criticisms of electronic cigarettes leveled by its opponents in the tobacco control movement is that there are many dual users of e-cigarettes and tobacco cigarettes and that this has adverse public health consequences.

The Michigan Medical Society has that would protect the public's health by prohibiting the sale of electronic cigarettes to minors.
