Hello guys,
It is very difficult to properly scientifically measure the risk for non-smokers of being exposed to second-hand smoke. To do a proper experiment, scientists would need to find a large group of people who had never been exposed to cigarette smoke before, split them into two groups, and then systematically expose one group to second-hand smoke for a period of time while the other group stayed smoke-free.
They would then have to wait and see if more of the group exposed to second-hand smoke developed lung cancer than the other group over their lives. This would be a very expensive and time-consuming experiment.
