A scientific review on electronic cigarettes was published by Stan Glantz and colleagues this week in the journal Circulation.

Peter Hajek, director of the Tobacco Dependence Research Unit at Queen Mary, University of London, also this critical flaw in the study: ""The authors followed up smokers who tried e-cigarettes but did not stop smoking, and excluded smokers who tried e-cigarettes and stopped smoking," he said. "Like smokers who fail with any method, these were highly dependent smokers who found quitting difficult. The authors concluded that e-cigarette (use) was not helpful, but that would be true for any treatment however effective if only treatment failures were evaluated."
