Federal, state and county officers seized about 29,000 marijuana plants across Hawaii in a 10-day Operation Green Harvest sweep from 31 May to 9 June 2005.[1][2] Maui County yielded 16,869 plants, the Big Island 10,418, Oahu 1,503 and Kauai 253.[1] About 10,000 plants stood on a single private estate on Molokai, within a couple of miles of the island’s airport.[1][2] Officers also recovered 36 pounds of processed marijuana and arrested six people for drug promotion, most of them on the Big Island.[1]

More than 125 officers took part, drawn from the DEA, the National Park Service, the state land department, the Hawaii National Guard’s counter-drug unit and all four county police departments, with seven to 10 helicopters overhead.[1][2] Some plots lay in parks and forests, but most were on private land.[1]

The sweep came the week the US Supreme Court upheld federal prosecution of medical-marijuana patients; the DEA’s Tony Williams said the mission was unchanged and aimed at cultivators, not the sick.[1] Officials valued the haul at about $29 million at $1,000 a plant and said cultivation had fallen far below the 1.9 million plants taken in 1987.[2]
