Here’s some further information on the global market in illegal drugs from Peter:
In 2003, the UN found that the illegal drug trade generated an estimated 321.6 billion dollars ( the latest year that the information is available). It constitues 0.9% of the world’s GDP, which is higher than 88% of countries in the world in the same year. The bulk of the money (214 billion) was sold at the street level.
Most of the buying was done in America (44%) followed by Europe (33%), with last place being held by Africa (4%)
