partly for undertaking studies funded by the tobacco firms to show that smoking was a less prominent cause of lung cancer than other forms of occupational exposures. It is odd to find this controversy resurrected once again. There is little doubt that smoking
causes lung cancer. There is also little doubt that exposures to occupational and environmental toxics contribute to this, as well as acting as causes in their own right. So I am not sure what point Susan Rosenthal is trying to make by pitting one against
the other. Seems very old hat, and not sure it warranted broadcasting.</span></p>
