Tobacco Industry Denial of Smoking Hazards

Record	OBS-0307
Category	Health/Pandemics
Status	DEBUNKED
Summary	The tobacco industry has a documented history of denying the health risks of smoking and undermining scientific evidence. This includes public relations campaigns and funding biased research to create doubt about the link between smoking and lung cancer.
Origin	The campaign began in the 1950s in the United States, following the publication of studies linking smoking to lung cancer.
Claimed	There is no proof that cigarette smoking causes lung cancer. Tobacco products are not dangerous. Low-tar cigarettes are safer. Secondhand smoke is not dangerous. Nicotine is not addictive.
Evidence / consensus	Extensive scientific evidence and expert consensus confirm that smoking causes lung cancer and other diseases, secondhand smoke is harmful, and nicotine is addictive.

> OBSERVER NOTE:
A classic case of manufactured uncertainty. The industry's internal documents contradict its public statements. Catalogued as a historical example of corporate disinformation.
