Scuse the snip from your thorough post, I'm sure that there is work ongoing to analyse those cost savings but it's a few years away yet as you say, at least. I'll ask a friend who is in medical policy research and see if she knows anything.
NHS has far more urgent issues to deal with, a possibly limited supply of critical medicines and a worsening staff shortage post-brexit being just two. They do need that data asap though in order to be able to plan future resourcing as the NHS is increasingly squeezed on all sides.
BT influence and cash is not so powerful in the UK these days as it is in the USA, it's there but the weight and reach of our academic institutions and the evidence based foundation of NHS research and practice has largely been able to fend it off.
I'll repeat my belief that the attacks on
vaping in the US are founded on a base of BT cash and it's deep and very effective influence within your legislative bodies and upon individual politicians...and the
vaping industry itself it seems.
The power of such influence is evident in the UK too, but we suffer in other spheres, take a look at the recorded business interests of MPs, Ministers and Peers - they own and/or "lobby" & consult for communications, energy, media, transport, prisons, parts of the NHS, arms related companies and so on. Fortunately not so much BT these days here.
Some folks insist on saying 'please don't politicise this
vaping struggle', that's missing the point by a long mile.
All I can say is do what you feel you have to do, good luck!
