Researchers at the Centre for Health Promotion and Disease Prevention in Detroit reviewed 34 personal injury claims brought against major tobacco manufacturers in the United States between 1986 and 2003.
The defence arguments used by the tobacco companies included: a lack of scientific proof that smoking causes cancer; denials that a plaintiff had lung cancer; or acknowledging that a plaintiff had lung cancer, but a kind of lung cancer not caused by smoking.
Tobacco companies' lawyers also argued that presence of other factors invalidated the plaintiff's claims that tobacco was solely responsible for their cancer, or that the plaintiff had exercised free will by choosing to smoke despite knowing the health risks.
The science became undeniableStarting in the late 1990s, the defence that there's no scientific proof to link cigarette smoking with cancer started to become less common as tobacco companies began to publicly admit that smoking causes cancer. However, at the same time, there was an increase in the use of the defences of mitigating factors and the plaintiff's exercise of free will.
"The cigarette companies, through their public admissions and courtroom arguments, seem to be saying: 'Yes, smoking cause lung cancer, but not in the people who sue us,' " the study authors concluded.
