Pence op-ed: ‘Smoking doesn’t kill’
Science is not Mike Pence’s strong point.
Pence has also shown a deep misunderstanding of basic public health principles in the past. In 2001, he wrote an op-ed declaring that “smoking doesn’t kill.” The evidence? “Two out of three smokers does not die from a smoking related illness.” Diseases are rarely the product of one thing. With lung cancer, for example, there’s a strong genetic component. Some people who don’t smoke will get lung cancer.1 Many people who do smoke will not. Relative risk, which measures the strength of the relationship between an exposure and a health outcome (smoking and lung cancer in this instance), is a funny thing; it can’t be used to measure the risk for an individual, only a group. And at that macro level, the risk of smoking is quite clear, as this oft-cited American Cancer Society chart shows.

Lung cancer isn’t even the most common negative health outcome from smoking. That distinction goes to vascular diseases that cause heart disease and/or stroke, and chronic obstructive pulmonary disease.
