§ 38. Mrs. Castle
asked the Parliamentary Secretary for Science whether he is aware of the evidence of the relationship between lung cancer and the methods of processing tobacco, details of which have been sent to him; and whether he will ask the Medical Research Council to examine this relationship and report upon it.
§ 50. Mr. Thornton
asked the Parliamentary Secretary for Science if he is aware of fresh evidence, details of which have been sent to him, that the way the tobacco plant is processed, rather than the tobacco itself, is the cause of lung cancer; and if he will ask the Medical Research Council to examine this evidence.
§ Mr. Denzil Freeth
The Medical Research Council considered some years 27W ago the hypothesis that lung cancer is associated with the smoking of cigarettes made from tobacco which has not been fully fermented. The available evidence, however, did not support that hypothesis. I have not received any fresh evidence on the subject, although I have naturally studied the Press report which the hon. Lady sent me.
