The details still seem a bit hazy as far as I can see, but the basic upshot seems to be that those opposing the regulations have been persuaded to compromise and accept some of McAvan's demands after apparently falling for the 'greater good' bullshit argument.
McAvan's bunch have in effect, emotionally blackmailed the pro vaping bunch by lumping in vaping with tobacco and saying if the some of parts about vaping aren't agreed to, then the whole thing would fail and big tobacco would be able to get away with no extra regulation too.
That's where the real issue lies for me.
The pro vaping lobby should have refused to do any deals that were linked in with tobacco and demanded that if the EU wanted regulation of vaping that it should be done completely separately to tobacco. While ever vaping is lumped in together with smoking, we will always be vulnerable to bullshit claims like the gateway theory.
Anyhoo, it appears that a 'behind closed doors' deal was done that allows vaping to stay out of medical regulation but the trade off was a limit on nicotine content per ml (20mg is being proposed), refillables are to stay for now but a review will be done in 2016 and flavourings can stay for now, but along with refillables, national governments will be able to bring in whatever individual regulations they feel fit.
That's how I've understood it so far.
The elephant in the room as far as I can see is that vaping is now a prime candidate to be classified as tobacco and thus be liable for the same huge 'sin' taxation as smoking. Perhaps that was the real point of threatening medical regulation in the first place? To divert attention away from the fact that the biggest stakeholders (governments due to taxation income) wanted to be free to tax vaping heavily with as little opposition as possible. If we think we've gained a compromise/reprieve of some kind, then we won't kick up such a stink when they slap a huge tax duty on eliquid?
After all, the busybodies need to keep funding their gravy train somehow or they'll all end up unemployed.
