The Center for Medicine in the Public Interest (www.cmpi.org), estimates that counterfeit drug commerce will grow 13& annually through 2010.  The CMPI study is cited by the WHO on its updated counterfeit pharmaceuticals fact sheet.

Counterfeit sales are increasing at nearly twice the rate of legitimate pharmaceutical sales and they are a money machine.  In 2010 CMPI estimates that fake drugs will geneate $75 billion in revenues — a 92% increase from 2005.  And the risks of detection and prosecution are low.
