The capsule is this particular colour of blue (http://i.istockimg.com/file_thumbview_approve/16297287/2/stock-photo-16297287-blue-and-white-pill-capsule-macro-with-clipping-path.jpg) with APO written on the blue side and 50 written on the white. Inside is a fine white powder. It may also be significant to mention that this pill was found in Canada. Can anyone help me identify this?
