The part about handlers being able to give cues to the dogs is 100% correct. It’s a real factor and a real problem.
However, there is more to the situation. It’s a misnomer to think that the dogs alert to the presence of drugs. They alert to the presence of smells, which can persist at detectable levels even long after the drugs are removed.
It’s akin to “where there’s smoke, there’s fire”. There are many situations where the smell of smoke lingers for a very long time, even after the fire is gone. Like when you can smell campfire on your clothes the day after camping.
