According to a report entitled the Afghanistan Cannabis Survey published on 31 March 2010 by the United Nations Office on Drugs and Crime (UNODC), Afghanistan is now the world’s main supplier of cannabis. It produces between 10,000 and 24,000 hectares every year producing an estimated 1,500 to 3,500 tons a year and production takes place in 17 of 34 provinces. Other countries have more land under cannabis cultivation, but yields are significantly higher in Afghanistan, enabling it to be the world’s most productive supplier of the drug. It also provides high economic returns owing to lower harvesting and production costs compared to other drugs such as opium.
