Cocaine drug packets were found in the gastro-intestinal tract of seven persons, charged with and arrested for presumed drug smuggling. Plain abdominal roentgenograms were positive in 4, while computer tomography of the abdomen (CT-scan) was necessary in 3 others to make the diagnosis. There were no signs of acute intoxication or bowel obstruction. All patients were treated with enemas and/or laxatives in order to evacuate the hidden packets; no complications occurred. A clinical description of the seven cases is followed by a short review of the literature, mainly focused on the possible complications of ingested drug packets and possible methods of removal.
