Moreover, the paper gets its history wrong when it notes that «Total cancer mortality rates did not decline until 1990, 25 years after the identification
of the effect
of smoking on
lung and other cancers...» Well,
actually, it was more like 50 years, because the earliest studies to connect smoking and
lung cancer were conducted not by NIH - funded scientists but by Nazi scientists in the run - up to World War II.4 By the logic
of the PNAS paper, then, ought we to be crediting the Nazi health science agenda with whatever progress has been made on reducing
lung cancer, rather than the incredibly protracted and difficult public health campaign (that, for the most
part, NIH had nothing to do with) aimed at getting people to cut down on smoking?
