Found a white pill, small, oval shaped, and has "c a" imprinted on one side with a line between the two letters to divide the pill, and on the other side is the cobalt (arrow) imprint. A friend was given these by someone he knew who claimed they were similar to clonazepam, but they do not fit the description of any benzodiazipines I can think of. In the meantime, I have advised my friend to not take any of the pills. We're both pretty curious, however, as to what they may be.
