Sure, it's poorly worded and reads like loaded propaganda, but most people won't even get past the conclusion;
"Smoking cessation with the use of electronic cigarette led to reversal of chronic idiopathic neutrophilia. The daily use of electronic cigarette may help preserve the beneficial effects of smoking cessation."
That sentence, (and the other references of the same kind), is lending credence to the mindset of "using e-cigs is not the same as smoking and should not be regarded as such" because it was the NRT of choice for this person. It's a legitimisation of e-cigs as an NRT and every little bit helps, (regardless of whether it's written like a propaganda piece or not).
