Sound familiar?1954 - Dr Cuyler Hammond
He has deep doubts aboutall the studies reported so far. He suspects that the interviewers of lung-cancer patients probably induce an emotional bias in their victims who will thereby be led to make suspicious confessionals of heavy smoking. He says that it is extremely difficult to find a control group with the matched characteristics, of age, social standing, occupational habits, and regional location, of any given sick group. He warns against the false premise which might be exposed to prove only that smokers produce earlier symptoms rather than more cancer. He suggests that even if there were no significant association between smoking and cancer in the general population, a telling one might be found in the hospital population. He is even sour about the claims of the filter-tipped cigarettes, remarking in his wry way that the carbon in tobacco smoke probably neutralises some toxic agents, and that if the filter removes those carbon particles ‘filter cigarettes would do more harm than good.’”
Not only was Dr. Hammond the Chief Medical Statistician [epidemiologist] for the American Cancer Society, but at the time of the publication of The Guardian piece in 1954, he was also a 4-pack a day smoker.
