A friend of mine got pulled by the police when sniffer dogs were being used a train station, he had some tablets, in a baggy, in a tin, in a rucksack with his clothes in, and the dog wandered past and sat down in front of him 8(

Apparently, sniffer dogs will react if the person has come into contact with cannabis smoke within the past few days, the amount of false positives they get from people who have been in the same bar/bus when someone lights up a joint is very high.
