4. Famous Issues in Epidemiology A second year medical student Ernst Wynder 1948, attended the autopsy of a two-pack-a-day smoker who had died from lung cancer collected case histories of lung cancer victims Captured the interest of thoracic surgeon Evarts Graham. He was a sceptical smoker. 1950 Wynder and Graham published a large case-control study that had used standardised interviews linking smoking and lung cancer In the following decade, hundreds of reports were published linking lung cancer and smoking Doctors were convinced of the health risks of smoking. Many doctors quit, including Graham, who quit in 1952, but died of lung cancer in 1957

Smokers were all life-long smokers, and ex-smokers were carefully excluded Conclusion: Life-long Smokers are 13-14 times as likely to get lung cancer as life-long never smokers

11. Taxation is the most effective measure around the globe –As taxes/prices increase, consumption falls A 10% increase in price reduces cigarette consumption by: –4% in developed countries, –8% in developing countries –People with low incomes (including youth) are more price-sensitive A 10% price increase reduces smoking as much as 10% among youth and poor groups Deters youth from taking up smoking
