Beware of big pharmaceutical companies offering to conduct studies, especially when the studies are of products that compete with their products. From Justus R. Hope, M.D. at thedesertreview.com:
In the 1950’s scientists Richard Doll and Bradford Hill published a study from the UK finding that the risk of lung cancer was related to the number of cigarettes smoked per day, and this risk was 25 times higher in those who smoked more than 25 cigarettes per day.
Other scientists, namely Ernest Wynder and Evarts Graham, found a strong association between bronchogenic carcinoma and smoking. 96.5% of men with bronchogenic carcinoma were heavy chain smokers compared to 73.7% of the general population. Several extensive studies within one year of each other found the same thing, cigarette smoking is strongly related to lung cancer, and the more one smoked, the higher one’s risk.
