Tobacco companies dump over 300 carcinogenic chemicals into cigarettes, called additives, to make them more addictive, and which make up half of nearly all cigarettes.[1]
That is what kills people, smoking carcinogenic chemicals. Unadulterated tobacco, such as what pipe smokers use, does not actually cause cancer, yet it shouldn't surprise us why cigarette smokers die in droves. The American Lung Associate did not discriminate: tobacco is bad! Yet all of this information came out during the late 1990's, lawsuit, US v. Philip Morris, and yet the settlement permitted tobacco companies to continue the practice of poisoning cigarettes. Half of the $200B+ settlement was forgiven by the mid-2000s.
But the US Surgeon General had different findings, and the only conclusion that we can make is that it is not tobacco that kills, only cigarettes:
Death rates for current pipe smokers were little if at all higher than for non-smokers, even with men smoking 10 pipefuls per day and with men who had smoked pipes for more than 30 years.[2]
Among the pipe smokers.... The US mortality ratios are 0.8 for non-inhalers and 1.0 for inhalers.[3]
Smoking
actual tobacco can cause emphysema, not cancer. But most commercial tobacco is intentionally poisoned to increase the addictiveness of nicotine, and the result is cancer.
