Héctor Luis Palma Salazar, commonly known as "El Güero Palma", is a Mexican former drug trafficker and leader of the Sinaloa Cartel alongside Joaquín "El Chapo" Guzmán and Ismael Zambada García. After his boss Miguel Ángel Félix Gallardo ordered the brutal murder of his family, Palma set out to avenge them. Palma was arrested on June 23, 1995, and extradited to the United States, where he served a jail sentence until June 2016. He was then deported back to Mexico and charged with a double homicide for murdering two Nayarit police officers in 1995. Palma is currently incarcerated at the Altiplano Prison near Mexico City.

The illegal drug trade, drug trafficking, or narcotrafficking is a global black market dedicated to the cultivation, manufacture, distribution and sale of prohibited drugs. Most jurisdictions prohibit trade, except under license, of many types of drugs through the use of drug prohibition laws. The think tank Global Financial Integrity's Transnational Crime and the Developing World report estimates the size of the global illicit drug market between US$426 and US$652 billion in 2014 alone. With a world GDP of US$78 trillion in the same year, the illegal drug trade may be estimated as nearly 1% of total global trade. Consumption of illegal drugs is widespread globally, and it remains very difficult for local authorities to reduce the rates of drug consumption.
