In general, I can see the
theory behind the idea that the NHS can be somewhat selective about its patients. Perhaps if the idea would be to make people realise that spending ridiculous (and rising) amounts to fuel their cigarette and/or alcohol addiction means no treatment for future related diseases, it would make sense. However, this is idiotic of me.
In agreement with what Shin has said, those of us who do drink and smoke make up one hell of a lot of their budget. It's income the government can't afford to lose, and yet despite paying this money we are not entitled to health services?
We're pretty much damned if we do and damned if we don't. If you are refused treatment on the NHS, then it may be a life or death matter of finding private treatment, which charges extortionate amounts. People just can't afford it.
EDIT: also, think about how much money drinkers/smokers are saving the government in terms of pensions; we'll die young, thus lowering the budget
Jam it back in, in the dark.
