TRENTON, N.J. -- New Jersey has halted training state police dogs to sniff out pot.
He says dogs already trained to detect the scent could be used in other settings where marijuana would be prohibited, such as jails and schools. He added that it's possible to train the dogs to detect marijuana in the future if needed, but it's impossible to "un-train" dogs who already recognize the odor.
Grewal spoke at an Assembly budget hearing after a lawmaker asked how police dogs would be affected if recreational weed becomes legal.
New Jersey would be the 11th state with recreational marijuana if a proposal goes forward.
This story has been corrected to say that the Assembly hearing was on Wednesday, not Thursday.
