Question By: Canine substance detection involves the use of specially trained dogs, commonly golden or Labrador retrievers, for the detection of illegal substances. Dogs of this kind are now being used in various different situations, such as
workplaces, airports and schools, to detect weapons, contraband, narcotic drugs, abused medication, alcohol, firearms and explosives. The necessity for this is due, in part, to the increasing incidents of drug abuse and violence among young people and employees, along with a growing need for increased security in schools and workplaces. Many schools and employers in the United States are now engaging "sniffer dogs" to improve safety and assist in the prevention of drug abuse. Supporters of this policy argue that the presence of these dogs, even if they do not immediately turn up illegal substances, provides a powerful deterrent.
There are also, however, a number of school principals and employers who are concerned about this method because they anticipate that the seizure of illegal substances would reflect badly on their institutions and companies. Nevertheless, the reality is that today narcotic drugs, alcohol, and weapons are discovered in schools and in addition account for an astonishing 70 percent of injuries at work.
Dogs trained to detect the scent of illegal substances are useful as they can utilize their acute sense of smell to penetrate many hiding places which are inaccessible to other detection methods. A dog has about 200 million sensitive cells in its nose, compared to about five million or so in a human being, and therefore, a dog's olfactory system is around 40 times more sensitive than that of a human.
