Yes it can sometimes be quite amusing the way that some smokers will defend their addiction habbit. I knew a lady who was into every sort of natural health food and took notice of every health scare. I'm sure that if she'd seen somewhere that drinking product with water in them was bad for you, she'd have quite happily died of thirst. She wouldn't use washing-up liquid, eat anything with an E number in it and was virtually vegan. Although she was so obsessed with health dangers, she virtually chain-smoked. When challenged about this, she always asserted that links between smoking and cancer, heart problems, respiratory deseases etc had never been proven. I'm sure she'd have still been saying this, if she hadn't died some years ago - of cancer.
