"The report says that over the last seven years (2002-2008), the transnational trade in Afghan opiates resulted in worldwide sales of $400-$500 billion (retail value). Only 5-10% of this is estimated to be laundered by informal banking systems (such as hawala). The remainder is laundered through the legal economy, and importantly, through Western banks."

Wait... What?
