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.[1] https://www.youtube.com/watch?v=gdV_1u-TodY&t=13m25s
