Here's a BBC Linky but the upshot is that, according to Public Health England, vaping isn't the big Satan that some make it out to be, E-Cigs should be available on prescription & that hospitals & employers should have designated vaping areas (even rooms for long stay patients).
It's about time some proper research was done & some recognition of the fact that it's just water & flavouring - "there was "overwhelming evidence" they were far safer than smoking and "of negligible risk to bystanders"....
Good news for those trying to give up fags, but it does mean that the frothers will have to find something else to froth about now......
