This is a report from the United States Government Accountability Office entitled

PRESCRIPTION DRUGS
Preliminary Observations
on Efforts to Enforce the
Prohibitions on Personal
Importation

I thought it may be of interest to users of IOP's. It talks quite a bit about the process used by the CBP (customs), FDA, & DEA in screening packages and regulations for importing medications. Although it is dated 7/22/04 I found it to be an interesting read.
