But officer, this isn’t my pot. Really!

Via Jamie Spencer comes this amusing story.

An unwitting passenger arriving at Japan’s Narita airport has received 142g of cannabis after a customs test went awry, officials say.
A customs officer hid a package of the banned substance in a side pocket of a randomly chosen suitcase in order to test airport security.
Sniffer dogs failed to detect the cannabis and the officer could not remember which bag he had put it in.
