K-9 sniffer dogs are at risk of losing their jobs due to more states legalizing marijuana
K-9 officer dogs that detect marijuana could be out of a job - because more and more states are legalizing the drug.
So far, more than 16 states have legalized marijuana for recreational use, while more have legalized the drug for medicinal use.
A dog’s sense of smell is two thousand times stronger than a human’s, according to security firm ICTS, therefore, they can be trained to find a variety of illegal drugs that humans would not be able to detect.
"Sniffer dogs have totally no interest in the drugs themselves. What they're actually searching for is their favorite toy. Their training programme has led them to associate that toy with the smell of drugs," ICTS reported.
