Yep, I know they still have the dogs that hit on it. That was my wondering about the chemical change that happens in cob....is it different enough that those places that still have K9s that hit cannabis won't detect it.I know they still have pups hitting on Weed at the Cali border to AZ
Maybe AZ will legalize it and they will get retired
The good thing is that to the human nose, cobs don't smell at all like cannabis so any human cops are going to be unlikely to pick anything up.
