The impact of this confounding is that it will bias the results towards finding that e-cigarettes are much less effective than other approaches. In fact, this is exactly what happened and it is the reason why the evidence that Glantz and others are citing to support their contention that e-cigarettes hinder smoking cessation is invalid.

If Stan does apologize and/or retract his false accusations, please send me a cable because I want to know about it right away. But I'm not holding my breath. The truth is just too much for idealogues like Glantz to take. It is only through lies that they can discredit the overwhelming experience of tens of thousands of vapers that these products are helping them to improve their health and potentially save their lives.

The Rest of the Story

Ironically, Stan Glantz criticized the study specifically because it examined the effect of electronic cigarettes on quitting among smokers who desired to quit. According to an in the New York Times: "Stanton A. Glantz, a professor of medicine at the University of California, San Francisco, said the study’s limitation was that it tried to measure the effect of e-cigarette use only among smokers who were trying hard to quit, not all smokers."
