It should be clear to readers that this study was poorly designed toinvestigate the efficacy of electronic cigarettes. The study systematicallysampled a group of quitline callers who were unsuccessful using electroniccigarettes. These people tried and failed using electronic cigarettes. How dowe know they failed? Because they wouldn’t have had to call the quitline ifthey weren’t still smoking. This is clearly a harder core group of smokers andit is no surprise that their cessation rates were lower after 6-months than thecomparison group. The study tells us nothing about the effectiveness ofelectronic cigarettes, other than that they do not work for everyone. In fact, this research is biased in favor of not finding aneffect of electronic cigarettes on smoking cessation.

I doubt that the smoke levels in New Jersey parks were anything like the levels that are being experienced by the tens of thousands of the state's casino workers.

Today, I express my opinion that the use of these studies to draw conclusions about the efficacy of e-cigarettes for smoking cessation is not just unscientific, but dishonest as well.
