So we shouldn't research anything related to the social sciences because some people might lie about it? What leads you to believe that smokers lie more than nonsmokers if not social science research?
It is my understanding that most surveys will include a margin of error. This story does not mention this, I wonder if this is just slight of hand while the east coast of the US falls into the sea?!

Doesn’t matter if it’s extremely difficult to get good data here. What matters is we can’t substitute bad data if that’s all we can come up with.
And although I stated it as smokers lying, the implication is that the nonsmokers are lying (by claiming to smoke).
