A study by Colombia’s National Association of Financial Institutions (ANIF) reported that worldwide street sales of Colombian cocaine, heroin and marijuana totaled US$ 46 billion in 1999. Based on the assumption that less than 10 percent of total sales are repatriated to Colombia each year, ANIF estimated that the country’s total earnings from the illicit drug trade amounted to approximately US$ 3.5 billion in 1999. This figure placed drug earnings close to the US$ 3.75 billion made from oil – the country’s top export – and more than two and one half times earnings from coffe exports in 1999
