Mexican drug cartels are organized crime groups involved in the production, distribution, and sale of illegal drugs, primarily in Mexico and the United States. These cartels often engage in violent conflicts with each other and with law enforcement, leading to significant social and economic impacts in affected regions. The most notorious cartels include the Sinaloa Cartel, the Jalisco New Generation Cartel, and the Gulf Cartel. They are known for trafficking drugs such as cocaine, methamphetamine, and heroin. Efforts to combat these cartels involve both local and international law enforcement agencies, but challenges persist due to corruption and the high demand for drugs.
