Taken from the Vapers In Power FB group I learn that a new article is to appear in the Lancet tomorrow. It refers to a new 'systematic and meta-analysis' which concludes unbelievably that :
As currently being used, e-cigarettes are associated with significantly less quitting among smokers.
That's right. Smokers are LESS likely to quit smoking if they use ecigs.

Luckily the sensible people knew this was coming and already published a full rebuttal

I particularly liked Professor Hajeks response
“This review is grossly misleading in my opinion. There are several problems with the way studies were selected and used, but the main flaw is simple, though not easy to spot. The studies that are presented as showing that vaping does not help people quit only recruited people who were currently smoking and asked them if they used e-cigarettes in the past. This means that people who used e-cigarettes and stopped smoking were excluded. The same approach would show that proven stop-smoking medications do not help or even undermine quitting.
“Here is an analogy: Imagine you recruit people who absolutely cannot play piano. There will be some among them who had one piano lesson in the past. People who acquired any skills at all are not in the sample, only those that were hopeless at it are included. You compare musical ability in those who did and those who did not take a lesson, find a difference, and report that taking piano lessons harms your musical ability. The reason for your finding is that all those whose skills improved due to the lessons are not in the sample, but it would not necessarily be obvious to readers.
“E-cigarettes are a major development in public health. It is unfortunate that their potentially huge positive impact is being hindered by excessive regulations triggered by misleading suggestions.”
We all know instinctively that Glantzs conclusions fly in the face of everything we know but expect the usual flurry of headlines soon
