Police seized 9,027 pounds (about 4.1 tonnes) of ganja hidden in export boxes of yams at the Gordon Cay container terminal in Kingston on 5 January 2003.[1] The Contraband Enforcement Team found the drug during routine checks of containers waiting to be loaded onto ships bound for the United States.[1]

The ganja was packed in cardboard cartons marked “Produce of Jamaica” alongside genuine yam cartons labelled “Product of Jamaica”, 248 boxes in all.[1] Police were alerted by the weight: an export box of yams standardly weighs 45 pounds, but these weighed 55 pounds.[1] The shipment was destined for New York and New Jersey.[1]

The paper put the street value at $1.4 billion.[1] No arrests had been made, though the head of the narcotics police, Senior Superintendent Carl Williams, said officers were following several leads.[1] Williams said a US-side discovery of the load would have hurt Jamaica’s yam exports, which at their peak reached over US$12 million a year.[1]
