I don't understand why so many of us want to dismiss anything that suggests that vaping can have a negative effect. Yes Vaping is 95% safer than cigarettes we all know this.
We all know that smokers should switch to vaping - but that's not because vaping is 100% safe, it's because it reduces the risk of potential harm. I welcome anything that helps to inform me in a reasonable way of what the potential harm may be, so that I can make informed choices!
I actually also welcome news coverage that actually links the the scientific paper - all of the data is there to be seen and scrutinised. The problem is that the media know that fear sells - so they take a rational and reasonable piece of research and insist on inventing a sexy / scary headline for it!
The scientists involved are not saying 'vaping is bad' or ' quit vaping' - They are simply saying 'we've done a small study and noticed something, this could do with being looked into more - but still switch to vaping if you smoke'. Surely that's exactly the sort of thing papers should want to see happening?
PS - I can't see a date for when the study was carried out, but the paper was originally submitted for review in Feb 2018.
