I hate to say it, but I don't think scientific proof is the issue here.
What we're dealing here is memes - powerful, destructive memes, but memes that are immature and based on older ones. I think they can be dealt with - but science isn't going to come good for us on this. If you don't know about memetics I suggest you read up - the
wiki article is a good start.
The "e-cigs as environmentally dangerous" meme originates, IMO, like this: The accepted wisdom is that 3rd hand smoking is dangerous - on further analysis, the evidence for this is clear: smoke contains a variety of chemicals that are dangerous when inhaled from the atmosphere (I don't know much about the current controversy over 3rd hand smoke safety, btw, although I think it's safe to say that no-one is truly meme-proof, not even the surgeon general). I doubt very much that nicotine is one of these chemicals - there are masses that are likely far more dangerous.
However, the meme itself is simply: "3rd hand smoking is dangerous" - the evidence doesn't matter; it has now become received wisdom.
The meme that is developing in the communities referenced above is: "3rd hand
vaping is dangerous" - the evidence doesn't matter, because the evidence no longer matters where
smoke is concerned. It's the received wisdom that gets copied across to the new meme, not the original, factual basis of the origin of the first meme.
Looked at this way, it seems to me that they best way to combat this is to repeatedly ask people what evidence shows that nicotine is dangerous in the atmosphere. Ask to be shown the evidence. Do not feel that the burden of proof is on you to show that e-cigs are safe to 3rd parties (an impossible task), but politely and reasonably question the logic.
And remember, this is not the same thing as insisting that they are safe - it's a question of thinking
through the issues in a logical way, and not being tied to dogma.
As one of our esteemed health professionals stated before, following Neitsche, if we are not careful we become our enemies. In this case, ex-smokers become like the
tobacco companies who for years obfuscated the growing body of evidence in favour of their own pre-created memes. "Smoking dangerous? Prove it!" they said, and despite overwhelming evidence that smoking is dangerous, they were able to deny it until a direct causal link was established. And even once smoking was proven to be dangerous, they created new memes: "OK, so smoking kills ya - but the cultural benefits far outweigh the dangers to individuals!" They paid for these memes too - Philosopher Roger Scruton was found to be
on the payroll of
Japanese Imperial Tobacco whilst pushing a pro-smoking message in the 80s. These memes are perpetuated today - Useful idiots like David Hockney claiming that smoking bans are
destroying bohemia
But this applies to e-smokers too - our best strategy is to use critical thought and to be wary of received wisdom setting in. Listen to TropicalBob; when he says, we don't know e-smoking is safe, believe him. We don't and we may never know for sure. All we can do is to be logical and critical of ourselves and others - if we do this, I think vaping will come out on top.
And by the way, this and the other communities/organisations are the reason, IMHO, why the tide does seem to be turning towards e-cigs - the standard of critical thought set by many of our community is very high, and it does get heard above the din!
