§ Captain Kerby
asked the Lord President of the Council and Minister for Science what official research is being carried out into the use of fluorinated aliphatic insecticides on tobacco plants 120W as a cause of lung cancer; and what has been the result.
§ Mr. Hogg
I am informed by the Tobacco Research Council that these particular substances are not recommended for the treatment of tobacco plants and have not to their knowledge been so used. Accordingly no research is in progress. The use of other insecticides on tobacco plants has been taken into account by those concerned with research on the relationship between smoking and lung cancer but no evidence has been found to suggest that they are a causative factor in lung cancer.
