Police Training Drug Sniffing Dogs to Ignore Marijuana - NBC Right Now/KNDO/KNDU Tri-Cities, Yakima, WA |

SEATTLE, Wash. - Washington State Patrol and other police agencies in the state are now training drug-sniffing dogs to ignore marijuana.

After voters legalized the drug in November, the State Association of Prosecuting Attorneys advised police to change their standards.

The Prosecuting Attorneys' Association also says an alert from drug-sniffing dogs is no longer enough evidence for a search warrant.
