In Washington State, it's no longer cool for drug-sniffing dogs to detect marijuana during a search. Police departments and State Patrol are busily retraining K-9s and training new ones.
This is a result of the passage of I-502 last November, which legalized the possession of up to one ounce of pot and directed the state to create a regulated marijuana industry.
Dogs now must use their considerable olfactory powers strictly to sniff out coke, heroin and meth, and not weed.
