Furthermore, traces of alprazolam, better known as the anti-anxiety prescription drug Xanax, and cough medicine, were also discovered in a significant portion of analyzed blood bank samples.

Richard van Breemen and Luying Chen, two scientists at Oregon State University, purchased 18 samples of what should have been pure human blood serum from a variety of different biomedical suppliers.
