Another W.D. Va. opinion on causation

In Boysaw v. Purdue Pharma, Chief Judge Jones granted summary judgment on claim against the manufacturer of OxyContin, because the plaintiff could not prove causation. The opinion cites the earlier ruling in McCauley v. Purdue Pharma L.P., 331 F. Supp. 2d 449 (W.D. Va. 2004).
