General Causation & Specific Causation
In any kind of lawsuit that alleges a specific product caused a certain type of illness, the plaintiff must prove both general causation and specific causation.
General causation means proving that the product in question is actually capable of causing the specific illness. Because there is absolutely zero debate that exposure to crocidolite asbestos can cause mesothelioma, a plaintiff doesn't have to do much to prove general causation if he or she was exposed to crocidolite.
Specific causation means proving that the product in question actually caused the plaintiff's illness. A plaintiff who was exposed to crocidolite asbestos and who developed mesothelioma will have to prove that those exposures to crocidolite caused his or her mesothelioma. For example, if the plaintiff worked with crocidolite for one weekend, but worked with amosite for thirty years, it will be difficult to prove that crocidolite specifically caused the illness.
Specific causation is most difficult if the illness is lung cancer and the plaintiff is also a smoker. Because smoking causes lung cancer, it would be difficult to prove a plaintiff's exposure to asbestos is what caused his or her lung cancer, regardless of how much asbestos he or she was exposed to.
