Depends on how much fiber is in their diet.
"The traffickers pay individuals, or "drug mules", to transport their product to a particular destination. Immediately prior to their assigned flight, the "mules" swallow cocaine packed in Teflon coated condoms or sausages. The sausages of cocaine are about the size of your index finger.
Now think about this carefully. The flight from Curaçao is approximately 9-10 hours from pushback to shutdown. If you include the time the passenger takes to check-in and collect his bags at the other end, then his journey can easily exceed 12 hours.
Consequently, at some point during a 9-10 hour flight, nature takes its course and the material has to come out the other end. If they have time, the "mules" wash the contraband and re-swallow it, hoping not to be nabbed by customs at their destination."
