CAUSE OF LUNG CANCER
Coating On Tobacco Leaf Blamed (N.Z. Press Association—Copyright) CHICAGO, April 12. A New York doctor today said that the waxy coating on tobacco leaf was a main source of chemicals in cigarettes reported as causing cancer. This coating could be “drycleaned” off, as one of four steps toward “safer cigarettes,” said Dr. Ernest Wynder, of the SloganKettering Institute, New York. He made three other recommendations: an effective filter, reducing the temperature at which cigarettes burn, and moderation in smoking habits. Reporting on recent cigarette studies to the American Association for Cancer Research, Dr. Wynder said that this waxy coating on tobacco leaf and stem was a major source of cancer-causing chemicals he said were found in the whole tar from concentrated tobacco smoke. Solvents could remove the coating and tests were planned on tobacco prepared with solvents, he said.
