Afghanistan has been the greatest illicit opium producer in the entire world, ahead of Burma (Myanmar), the "Golden Triangle", and Latin America since 1992, excluding the year 2001. Afghanistan is the main producer of opium in the "Golden Crescent". Opium production in Afghanistan has been on the rise since U.S. occupation started in 2001. Based on UNODC data, there has been more opium poppy cultivation in each of the past four growing seasons (2004–2007) than in any one year during Taliban rule. Also, more land is now used for opium in Afghanistan than for coca cultivation in Latin America. In 2007, 92% of the non-pharmaceutical-grade opiates on the world market originated in Afghanistan. This amounts to an export value of about $4 billion, with a quarter being earned by opium farmers and the rest going to district officials, insurgents, warlords, and drug traffickers. In the seven years (1994–2000) prior to a Taliban opium ban, the Afghan farmers' share of gross income from opium was divided among 200,000 families. In addition to opiates, Afghanistan is also the largest producer of cannabis (mostly as hashish) in the world.
