Smoking high tar cigarettes increases risk of death from lung cancer, but no differences in risk for smokers of very low, low and medium tar cigarettes - 24/08/11
Abstract |
Question |
What is the relationship between lung cancer mortality and tar rating of smoker's cigarette brand?
Study Design |
Multivariate analysis of data from prospective cohort study.
Main results |
Risk of death due to lung cancer was significantly higher in smokers of high-tar cigarettes compared with people smoking low, very low and medium tar cigarettes (see Table 1). There were no significant differences in the risk of lung cancer mortality for people smoking very low or low tar cigarettes compared with smokers of medium tar cigarettes. Stopping smoking considerably reduced risk of lung cancer. People quitting before age 35 years had a very similar risk to those who had never smoked.
