Clearly, the actual scientific evidence doesn't matter to an agency that is being guided purely by ideology and which has come to a pre-determined conclusion that e-cigarettes are evil. Today's story demonstrates how a strong pre-existing schema, propped up by ideology, leads to such preposterous scientific statements such as arguing that although many ex-smokers have used e-cigarettes successfully as a cessation aid, there is no evidence that any ex-smokers have used e-cigarettes successfully as a cessation aid.

Last November, I reported that CDC was by telling us that an agency survey had found that electronic cigarettes are a gateway to smoking. Specifically, I noted that CDC director Dr. Thomas Frieden : "What we are doing first is tracking, and we are seeing some very concerning trends. Use of e-cigarettes in youth doubled just in the past year, and many kids are starting out with e-cigarettes and then going on to smoke conventional cigarettes." However, the CDC was a cross-sectional one and it didn't track e-cigarette users over time to see whether they went on to smoke conventional cigarettes. Thus, Dr. Frieden was lying to the public.

To make matters worse, Dr. Samet is not just an author, but served as one of the two editors of the report.

Trueba et al. also found that higher depressive mood was associated with greater reductions in exhaled nitric oxide.

Researchers from the Center for Tobacco Control Research and Education at UCSF have published a in JAMA Internal Medicine which purports to show that electronic cigarettes are ineffective for smoking cessation.
