The UK does not conduct an independent assessment of levels of heroin production in Burma. We rely on the internationally accepted reporting from the United Nations Office of Drugs and Crime (UNODC) available at: http://www.unodc.org/unodc/en/world_ drug_report.html. According to their 2005 World Drugs Report it is estimated that 370 tons of heroin were produced in Burma in 2004. The UNODC did not provide figures for heroin production in Burma for 2005 or 2006.
