But what is the clinical meaning of this effect? In order to find that out, one needs to conduct studies with longer-term end points.

Because this research was funded by the federal government (by the Army Research Office, to Cornell), it is subject to the human subjects research requirements. In addition, the involvement of two researchers at academic (federally-funded) institutions requires that the research be approved by an Institutional Review Board. Apparently, the research was approved by an academic IRB, a decision which I publicly question, for the above reasons.

The problem is that the smokers who used e-cigarettes were likely more heavily addicted and more resistant to quitting. The reason they tried e-cigarettes was probably related to their failure to quit smoking using other types of therapy, such as NRT or other drugs. E-cigarettes, after all, are not generally the first smoking cessation approach that a smoker will try.

To highlight the absurdity of this aspect of the deeming regulations, it means that electronic cigarette companies will not be allowed to even claim that their product is free of tobacco. The law states that a tobacco product manufacturer cannot claim that "the tobacco product or its smoke does not contain or is free of a substance." In other words, an electronic cigarette company cannot claim that its electronic cigaretes do not contain, or are free of, tobacco.

"They aren't harmless."
