"There is no way of proving that second-hand smoke caused his cancer, it's very unlikely that it did, and non-smokers get lung cancer too."
I worked in palliative care and have had lung problems, my Mum has lung cancer, I attend her appointments with her.
I don't understand why even though they have given her one bout of radiation, she carries on smoking.
I wanted to point out that there are different types and ways that tumours grow and "lung/cancer consultants" can make statements as to why people develop cancer, so " Roy castle syndrome" doesn't exist, people do get cancer from passive smoking. Consultants can tell why tumours develop and how they will grow.
I live in an area which has the highest rate of lung disease (North West), we know why people suffer from whatever lung problems they develop and what could of been done to prevent it.
Thanks to the under developed nations taking up smoking, we have gained better knowledge, as it isn't a coinsidence that we are seeing lots of problems that never existed before, without the use of cars increasing. China, for example has a high rate if lung cancer in those working in the lace trade, because they breathe in fibres, but it appears differently to a smoker.
Lungs are only one aspect, my Mums vascular problems and her needing to use a wheelchair is through smoking.
I don't have a strong opinion, two of my DD's smoke, my middle one is desperate to stop, because it is a waste of money and she likes clothes.
I think the financial argument is irrelevant, if smokers wasn't buying fags then they would be spending it on other things, or perhaps doing sports/hobbies which take up NHS resources, when injuries occur.
My hate of smokers comes from my hate of litter. Most smokers I know don't see themselves as littering.
I used to use sunbirds a lot when I was younger, but if I was short of money, I didn't. I found it hard to understand how my friends, who lived on Income Support and were good parents in every other way, could justify spending money daily on something so non essential and all round damaging.
But that is my thoughts to people that I care about, I wouldn't have an opinion on people that I don't know.
