Out of a very large NW London trust, I knew three who did not. Annoyingly, all three of them the very ones I worked with, but hey!
*I* will happily say that.
As a HEAVY smoker, I don't expect to get a flippin' thing of the NHS. MY choice to smoke, MY problem.
Same for anything else that is knowingly and repeatedly self-inflicted. There are kids out there who cannot get life-saving treatment for afflictions not their fault, all because people smoke like a chinmey, drink like a fish and laze around watching TV all the time.
Speaking of drinking - I saw far too many people wait far too long for quite serious treatment, because beds were taken up by drunken morons. Getting them in takes cops and paramedics off the streets, while keeping them takes A&E staff away from more important matters.
Chuck them in a drunk tank for the night and be done with it. That's what we used to do and it worked fine.
