Background: Lung cancer from cigarette smoking may have been overcome by an attractive Johannesburg housewife, Mrs Mildred Laurence, who has adapted a party trick to lower the burning temperatures of cigarettes.
Mrs Laurence read last year that Dr. Ernest Wynder, who is in charge of the official investigation into lung cancer in the United States, had said that the main cause of lung cancer was the high burning temperature of cigarettes. This was 680 degrees. At this heat tars containing carcinogenic hydrocarbons were released. None of these cancer-causing substances is produced when tobacco burns at 780 degrees.
Vast sums are being spent in America on finding a method to reduce cigarette temperatures; and Dr. Wynder has written Mrs Laurence a number of enthusiastic letters saying he thinks she may have found the answer.
Mrs Laurence - herself a non-smoker - remembered a party-trick with a cigarette, a handkerchief and a two shilling piece. She demonstrated by placing a floring underneath the handkerchief, and then placing a lighted cigarette on the part covering the coin. She let it remain there for about eight seconds and on removing the cigarette, there was not even a brown stain on the handkerchief. The coin was almost too hot to hold. In other words, the coin had grown all the heat away from the handkerchief.
Mrs Laurence went to work with powdered aluminium, copper, or various metal foils. And also with a cigarette paper metalised on the inside.
Mrs Laurence expects some difficulty in getting these cigarette papers made, because officially the tobacco industry does not accept that there is a relation between smoking and lung cancer. But the United Tobacco Company has been co-operating in secret with Mrs Laurence, although they do not admit themselves the dangers of cigarette smoking.
