Health, read the study. The CDC statistics are based on flawed methodology.
Their methodology is like yours, you say you know two people, one a smoker and one, a secondhand smoker.
According to you, they both died of lung disease or cancer. You’re saying, that the second hand smoke caused the lung cancer. The study proves that the lung cancer was not caused by secondhand smoke.
The CDC will still view it as such, because of people like you which assume that that’s the reason. Their numbers come from Hospital statistics, that for example, such-and-such amount people who were victims of secondhand smoke have cancer. They don’t know what caused it. THEY ASSUME it’s because of second-hand smoke. Actual Studies have proven that not to be true. Correlation doesn’t equal causation.
