V-J Auto Parts, 943 A.2d 216 (Pa. 2007)—asbestos plaintiffs routinely offered expert testimony that any exposure, no matter how minor, was sufficient to impose liability because “each and every breath” of asbestos-contaminated air was a “substantial factor” in causing illnesses such as mesothelioma. No longer.
