I'm given to understand that they can't train dogs with trace amounts of cocaine, by the time they were done, the dogs would be addicts, or dead. In the case of cocaine, they are trained on the scents of a common contaminant, the exact identity of which is kept secret.

I do know that the chemical company Sigma-Aldrich sold training scents for canines, for dogs to be trained to detect bodies, and other things. You can just buy those if you have a lab, there didn't seem to be specific licenses or permits needed, unlike for many other chemicals.
