Estimated Worldwide Cocaine Seizures According to UNODC
"Global production of cocaine (expressed at a purity of 100 per cent) can be estimated for 2014 at 746 tons (using the “old” conversion ratio) and 943 tons (using the “new” conversion ratio); those values are slightly higher than in the previous year but still 24-27 per cent lower than the peak in 2007, and thus back to the levels reported in the late 1990s. There are, however, indications that the overall upward trend observed in 2014 continued into 2015.
"Data suggest that the global cocaine interception rate, based on cocaine production estimates and quantities of cocaine seized, reached a level of between 43 and 68 per cent in 2014.
"Most of the increases in the global cocaine interception rate occurred after 1998, when the General Assembly held its twentieth special session, dedicated to countering the world drug problem together. The global cocaine interception rate almost doubled between the periods 1990-1997 and 2009-2014."
