Some of the most important conclusions in epidemiologic research have come not from large case-control or cohort studies or clinical trials, but from case studies or case series, or as Dr. Frieden would say, "anecdotes."

These studies are simply ignored by the Surgeon General's report and by my colleagues who have attacked me. It would be one thing if there were no evidence for my opinions, but it's hardly appropriate to attack an individual for expressing an opinion that is backed up by scientific studies.

While it is difficult for me to have to criticize anti-smoking groups because these are groups with which I have had a career-long collegial relationship, it appears that these groups are substantially harming the health of the public by impeding smoking cessation. Sadly, this means that their efforts are going to result in a significant amount of unnecessary disease and death.

It is perfectly reasonable for the government to intervene to prevent companies from making false or misleading claims to the public. Even severe infringement of free speech by corporations may be justified in the case of preventing the deception of consumers. However, there is little justification for prohibiting companies from telling consumers the truth, and there is no justification for suppressing the truth when those facts are the most pertinent information that the consumer needs to know in order to make an informed decision about using the product.

The weakness of the scientific argumentation of those opposed to electronic cigarettes demonstrates that in 2014, there simply is not much of a scientific argument to fall back on in opposing this innovation. The science isn't going to do it, so opponents have to rely on trite and meaningless assertions like:

The very idea that one would extrapolate from a study finding that vaping, like smoking, reduces exhaled nitric oxide levels to the conclusion that smoking may be no more hazardous than vaping in terms of its acute pulmonary effects defies scientific logic. It also shows a misunderstanding, or at least a misinterpretation of the meaning of exhaled nitric oxide findings.
