How good are drug dog's scents?

Tell me how good drug dogs actually are at finding hidden drugs. I mean, can they be outwitted. Are there certain conditions that they can’t smell the drugs? I basically just want to know if their skills are as good as people think.

My guess is that they are pretty good at what the do.

We are not going to help you outwit them.
