Like TLomon mentioned the tobacco industry is part of a well known conspiracy of the past. The tobacco industry was behind a PR campaign that counteracted scientific evidence which linked cigarette smoking to lung cancer.
Cigarette smoking accounts for about one-third of all cancers, including 90 percent of lung cancer cases. Smokeless tobacco (such as chewing tobacco and snuff) also increases the risk of cancer, especially oral cancers. In addition to cancer, smoking causes lung diseases such as chronic bronchitis and emphysema, and increases the risk of heart disease, including stroke, heart attack, vascular disease, and aneurysm.
