Narco-trafficking, also known as drug trafficking or drug smuggling, is the illegal trade of drugs and controlled substances. This illicit activity involves the production, distribution, and sale of narcotics such as cocaine, heroin, methamphetamine, and marijuana. Narco-trafficking often involves organized crime groups, cartels, and networks that operate across national borders to transport and sell drugs for profit. This illegal trade has significant social, economic, and political impacts, contributing to violence, corruption, and instability in many regions of the world. Governments and law enforcement agencies work to combat narco-trafficking through enforcement efforts, international cooperation, and drug prevention programs.
