How long was asbestos used?

The study is equally interesting for non-smokers and smokers, if one asks how risky asbestos exposure is both in comparison to and in connection with smoking. The TE or other interested readers can draw their own conclusions from it or not. You’re welcome.

... Not that this would deter any smoker....

Because it completely disregards the individual's genetic predisposition; how else could non-smokers die from so-called typical "smoker diseases"? Just my 2 Coins Rhineland greetings

Elina,

although these were certainly interesting pieces of information that I did not know before, it will not really help the OP who is crawling around in the attic and has direct contact with the insulation material.

He should definitely have a sample analyzed. That was already told to him further above.

Construction expert, passive smoking is also very dangerous. And lung cancer is also caused by any kind of fine dust, for example wood dust or stone dust are also carcinogenic. If interested, I really recommend the presentation by Ulrich Keil that I quoted above. Links are not allowed, but it reads very smoothly and contains a wealth of data on this topic.
