The <em;Swiss Medical Weekly</em; published a detailed critique of Gmel et al's well-done longitudinal study of Swiss 20 year-old men that showed that (1) smokers who used e-cigarettes were less likely to quit cigarettes than smokers who didn't use e-cigarettes, and (2) nonsmokers who started with e-cigarettes were much more likely to be smoking a year later than those who did not use e-cigarettes.
It is worth reading both the critique (available" target="_blank";here) and the response (available" target="_blank";here).
The critique, by Philippe Poirson, a blogger on" target="_blank"; and member of the Helvetic Vape association, makes all the same arguments that vaping enthusiasts, including the "experts" that they like to cite; Gmel et al nicely summarize these criticisms:
a) that a study among young people has to support the same conclusions as studies among older people or in the general population at all ages;
b) that an epidemiological study on general use of e-cigarettes must reach the same conclusions as smoking cessation trials among heavy smokers;
c) that data need to be broken down (heavy smokers that at some point in time become daily vapers using 3rd generation vaping tanks) until the desired effect is found;
d) and that we should overload an article by plugging in all the many analyses that he would like to see.
Gmel and colleagues, in simple language, explain why these criticisms are, at the very least, not all that important.&nbsp; They also do a nice job of pointing out the extensive self-citation that e-cigarette enthusiasts engage in (while ignoring or dismissing anything that does not agree with their positions) and, importantly, the kid of non-substantive nit picking that they use to attack work they don't like.
The contribution to this back-and-forth is valuiable well beyond the specifics of the one paper under discussion.&nbsp; Again, the critique is" target="_blank";here and the response is" target="_blank";here.
