Today, I discuss the reasons why hiding a conflict of interest like this is problematic.

The Marini study demonstrates that electronic cigarettes do lead to a reduction in exhaled nitric oxide, which suggests that they have a mild respiratory irritant effect and induce some inflammation in the airways. This is a finding which has been reported previously in a number of studies. It is not surprising because propylene glycol is known to be a mild respiratory irritant.

Furthermore, later in the paper they reinforce this point more specifically, writing: "the cross-sectional nature of our study does not allow us to identify whether most youths are initiating smoking with conventional cigarettes and then moving on to (usually dual use of) e-cigarettes or vice versa...".
