Summary

You must not on purpose make, sell, have with the plan to sell, or secretly put illegal drugs on a covered vessel. You also must not destroy or try to destroy property that can be seized for drug crimes on that vessel — for example, throwing things overboard, sinking, burning, or hurriedly cleaning the boat to hide evidence. You may not hide more than $100,000 in cash or similar money instruments on your body, in luggage, cargo, or in hidden compartments of a vessel that is set up for smuggling. These rules apply even if the act happens outside U.S. waters. There are narrow exceptions. They do not apply to a regular carrier or its worker, or to a U.S. government ship or its crew, if the drugs are listed on the ship’s manifest and are meant to be legally imported to the destination for medical, scientific, or other lawful reasons. If you claim an exception, you must bring the evidence; the U.S. government does not have to disprove it. A "covered vessel" means a U.S. vessel or one under U.S. jurisdiction, or any other vessel if the person is a U.S. citizen or a U.S. resident alien.
