Whatsup guys? I posted this question in another forum and didnt get a real answer to my question. How long can a drug dog smell weed or other drugs in a car after the drugs are gone. I smoke weed in my car so Im sure they could pick up on it, im just wondering how long after? Also more directly to the citzens of the box, can drug dogs smell opiate pills? (loratab, oxy, etc.) Peace
