Which law prohibits possession of controlled substances on vessels arriving in or departing from the U.S.?

The law that prohibits possession of controlled substances on vessels arriving in or departing from the U.S. is 21 USC 955. This specific statute addresses the importation and exportation of controlled substances, particularly in the context of maritime operations. It establishes clear legal boundaries for individuals and vessels to ensure that controlled substances are not transported across U.S. borders without proper authorization.

This law plays a crucial role in maritime security and drug interdiction efforts, reinforcing that vessels must adhere to strict regulations regarding drug possession and trafficking. By focusing on vessels that are involved in international trade and travel, the statute helps the government monitor and control the entry and exit of potentially dangerous substances.

The other laws mentioned, while related to drug offenses and maritime operations, do not specifically target the possession of controlled substances on vessels in the same explicit manner that 21 USC 955 does.
