U.S. Postal Inspection Service’s Oversight of Mail Suspected of Containing Illicit Drugs at Postal Facilities

The Postal Inspection Service established the Proper Handling of Suspected Marijuana Parcels Mandatory Stand-Up Talk in FY 2019 as guidance for postal employees on how to handle mail suspected of containing illicit drugs (suspected mail). In addition, the Postal Inspection Service’s Administrative Nonmailability Protocol policy describes procedures for recording referred suspected mail by postal employees. This policy was established primarily to remove marijuana from the mailstream. Our objective was to evaluate the U.S. Postal Inspection Service’s controls for handling mail suspected of containing illicit drugs at U.S. Postal Service facilities.
