I am pretty sure these dogs are trained on explosives not drugs. The amount of people that interact with drugs in the airport it would be a busy busy dog. Many people allegedly smoke before they head into the airport but you will see these dogs go right past them.
I have seen drug trained dogs in action and they can smell a small amount of weed, even just traces of recent contact they are pretty amazing at what they do.
