Trafficking is the act of transporting or trading illegal goods or people. This can include drugs, sex, or humans.

• Drug trafficking: the illegal transportation and sale of drugs such as cocaine, heroin, and methamphetamine.
• Sex trafficking: the illegal trade of individuals for sexual exploitation, often involving force, fraud, or coercion.
• Human trafficking: the illegal trade of individuals for forced labor or other forms of exploitation, such as domestic servitude or organ harvesting.
