Asbestos is a known carcinogen that the government has placed restrictions on for decades. Companies that work with asbestos have to have certain protections in place to limit the amount of exposure their workers experience. Many companies can no longer use asbestos for certain kinds of products as a means of limiting how much asbestos exposure the average person has in their lifetime.
Johnson & Johnson, the monolithic health and beauty company, has long denied the potential for asbestos contamination in their talcum powder products. Marketed as baby powder, this popular Johnson & Johnson product was sold for years to mothers, as well as to adults who wanted to freshen their genitals and avoid dampness in their underwear.
We certainly know that asbestos exposure can lead to cancer. There's a reason that the use is largely banned, even though it is a terrific insulator. It's just too dangerous. Too many people have passed away after getting exposed to it, at different levels of exposure.
