Body packers and drug concealment

What it is

The internal carrier (body packer, "mule") carries drugs in packets that are swallowed or inserted into the rectum or vagina. This differs from the "body stuffer", who hurriedly swallows a small, poorly wrapped amount to avoid arrest. The drugs most often carried this way are cocaine and heroin, and also amphetamines, ecstasy and cannabis. There are two medical risks: rupture or leakage of a packet, with severe poisoning, and bowel obstruction. For the forensic doctor the packets are both the possible cause of death and evidence that must be counted, described and handed over with chain of custody.

How to tell it apart

• Versus an overdose from use: in a carrier, the toxicology is explained by a ruptured packet in the gut.
• Versus other foreign bodies: uniform shape and density, in numbers, with circumstances of travel or arrest.
• Radiograph false positives: stones, calcifications, impacted stool; false negatives: newer wrappings or poor technique.
• The patient's history is unreliable: they may deny carrying packets.

How to recognise it

• Living: abdominal pain, distension or vomiting (obstruction), or signs of cocaine poisoning (seizures, cardiovascular collapse) or opioid poisoning (miosis, respiratory depression).
• Imaging: multiple uniform oval foreign bodies in the gut; a dense rim or mixing with stool suggests rupture.
• Autopsy: packets in the stomach, bowel, rectum or vagina; one open or empty; signs of the related poisoning.
• Obstruction, bowel ischaemia or perforation may coexist.

How it forms

• A leaking packet suddenly releases far more drug than ordinary use.
• By their number and size, the packets can block the bowel.
• Home-made wrappings, or wrappings damaged by gastric juice, break more easily.

Next step: what to do and document

• Treat the medical emergency first: a carrier with signs of poisoning or obstruction is an emergency, whether or not in custody.
• Record in the chart the imaging findings, the number of packets passed or removed, and the time.
• Hand over every packet recovered as evidence, with chain of custody; do not open or test it.
• Document what clinical information you share with the authorities and on what basis: review the limits of confidentiality.
• If the carrier dies, the case goes to a medico-legal autopsy: keep the clothing, the admission samples and the images.

Common mistakes

• Ruling out packets because the plain radiograph was normal.
• Using oral contrast to look for packets: it can hide them.
• Counting the packets passed without confirming by imaging that none remain.
• Attributing death to an "overdose" without locating and describing the ruptured packet.
