A botched customs test at Narita Airport in Tokyo has bestowed an unusual welcome present on an unknown arriving passenger. The BBC reports:  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. Anyone finding the package has been asked to contact customs officials.Japan is renowned for its hospitality, but this is going a bit far. Imagine if the victim had been caught and the customs officer's memory remained equally poor. Hat tip: Airliners.net(Read Full Post)
