 Fentanyl's death toll in central North Carolina has many law enforcement agencies now working to have their drug-detecting canines trained to sniff out the drug.

According to the state office of the chief medical examiner, last year alone, 3,340 people in the state died with the drug in their system. I'm Shadati Argetel.
