I am not spreading ill informed bullshit, I'm asking questions.
Oh yeah, you haven't linked to any of the dodgy studies or reports, I'll give you that. Nevertheless, you have spent pretty much all your time on this thread spreading fear, uncertainty and doubt with your 'questions'. Your very first post suggested that any research that found vaping not to be harmful was not to be trusted.
Then we had 'Smoking used to be harmless, too, apparently... Sometimes you don't actually need years of research to know something is bad for you and those around you - the research is just there to quibble about just how bad it is', then 'My fear is, the promises about the safety of vaping are a bit like the promises about diesel cars.' and 'I guess we'll just have to find out the hard way how harmless or harmful it is.' and 'of course, making it appealing eventually appeals to non-smokers and it can become fashionable like smoking was' and 'those people who do not want to breathe in other people's vapes have to wait for 50 years for the proof that inhaling something unnecessarily is actually harmful for non-smokers' then a reference to 'a contaminated e-cigarette product that harms the user' and 'We don't know how significant the risk would be from a massive increase in social vaping in public spaces.' and 'Why allow the widespread use in public spaces of something unregulated for which the long term health risks are largely unknown?' and 'young people who have never smoked are beginning to try it out for social reasons' and 'Who knows what's coming out of the unregulated ends of e-cigarettes and even if the user knows what's in them (unlike the passive vaper), who knows as of yet exactly how safe they are to inhale? It really is not that long ago that even doctors told patients that cigarettes were good for clearing the chest.' and blah blah blah.
You haven't linked to anything because you haven't bloody read anything, including the PHE and ASH links I have repeatedly provided. If you had, you'd have come across the evidence on changes in harm perception and why it's now a research priority for public health. Here we go again:
ASH:
Between 2013 and 2017 the perception of harm from e-cigarettes has changed. A growing proportion of the public and smokers fail to recognise that e-cigarettes are less harmful than smoking. In 2017 only 13% of adults correctly identified that e-cigarettes are a lot less harmful than smoking compared to 21% in 2013. In addition, the proportion of the adult population thinking that e-cigs are as harmful, or more harmful, than smoking nearly quadrupled from 2013 to 2017 from 7% to 26%.
People who are currently using e-cigarettes are more likely to have accurate perceptions of harm. Among all those who are currently vaping (smokers and ex-smokers) 49% accurately identify that e-cigarettes are a lot less harmful than smoking.
However, the poor understanding among smokers in general about the relative harms of e-cigarettes compared to smoking is of concern. In 2017 the proportion of smokers who said they did not know whether e-cigarettes were harmful relative to smoking was almost at the same rate as it was in 2013 (29% in 2013 and 28% in 2017). In addition, the proportion of smokers who think e-cigarettes are just as, or more, harmful than smoking has increased significantly from 9% in 2013 to 22% in 2017. Over this period evidence has grown about the relative safety of e-cigarettes when compared to combustible tobacco.
Smokers who have never tried e-cigarettes are less likely to accurately believe they are a lot less harmful than tobacco smoking than smokers who are currently using e-cigarettes. Among smokers who have never tried an e-cigarette 1 in 3 (30%) believe e-cigarettes are more or equally harmful as smoking. This is a view that has grown over time among smokers who have not tried an e-cigarette with 25% holding this opinion in 2016.
Pics are from ASH.
The PHE report discusses ASH's findings, along with similar findings from countries around the world (see chapter 8 - yes, there's a whole chapter dedicated to the topic). They conclude:
Although the majority of adults and youth still correctly perceive EC to be less harmful than tobacco cigarettes, there has been an overall shift towards the inaccurate perception of EC being at least as harmful as cigarettes over the last year, for both groups.
Policy implications
- Clear and accurate information on relative harm of nicotine, EC and tobacco cigarettes is needed urgently.
- Research is needed to explore how health perceptions of EC are developed, in relation to tobacco cigarettes and NRT, and how they can be influenced.
You don't really need to read anything though do you, because you're not interested in any answers or 'checking sources'. You can read fuck all and still endlessly churn out your FUD-inducing 'questions'.
You are part of the problem and it would be good if you could stop it.
And if exisitng smokers are put off vaping because of scare stories which they cannot be bothered to research, yet continue to smoke, despite knowledge of the facts, then I think they are the ones with a serious problem with the way they think, not those who ask for proof before something they have no need of is waved in their face by people who aren't interested in asking questions.
So having embarked on what looks like a very deliberate campaign of 'fear, uncertainty and doubt' despite having done no research yourself, and having completely ignored the reputable studies and reports you have been given, you are now attempting to blame smokers for not being 'bothered' to research and not being 'interested in asking questions' 
Smokers and vapers are constantly bombarded with the sort of doubt-inducing 'we just don't know' rhetoric you seem so fond of. Add in all the seriously biased bad science and the irresponsible press reporting around vaping and is it any wonder they are left not knowing what to think? And frankly, I don't care if some smokers and vapers can't be bothered to read up for themselves. I don't care if some of them can't read at all. Their lives and health are worth just as much either way.
I'm not finding any more links for you. You can do your own research from now on, and if you say 'we just don't know ...' I will say well of course you don't, you haven't read anything.
