There was something I learned about cigarettes that was confirmed in a cardio-pulmonary center where I worked: A specialist speaking to a room of about 75 peers stated that the research shows the primary cause of lung cancer in smokers is radioactive isotopes (polonium 210) taken up by the roots and deposited in the leaves. Rock phosphate fertilizer is the source of the polonium.
