What Stan does not reveal in his review article is that instead of estimating cessation rates among a cohort of smokers who made quit attempts using these products, the Vickerman study analyzed cessation rates of a large number of smokers who had previously tried to quit using e-cigarettes but failed, and then called a quitline because they had failed and wanted to try again. Then, they compared the quit rate among these smokers to that among smokers without such a history of a failed quit attempt using electronic cigarettes.

Despite its massive 978-page length, the new Surgeon General's - released last Friday - fails to include any mention of the many population-based studies which have shown that unaided smoking cessation is superior to the use of nicotine replacement therapy (NRT).
