Figures from these studies can be interpreted in any number of ways, but the fact remains that second hand smoke does cause cancer, it is also a fact that not all lung cancer is caused by second hand smoke. A study that claims second hand smoke doesn't cause cancer may have a number of things wrong with primarily that the sample they used was too small. Of the smoking related deaths in the UK, 11000 of them last year were caused by passive smoking, but I suppose that's just speculation and suppositions that plucked that number from the air.
