The Miami cocaine cowboys were a group of drug dealers and smugglers who dominated the city's cocaine trade in the 1970s and 1980s. The group was led by figures such as Griselda Blanco and Pablo Escobar, who became infamous for their brutality and cunning. The cocaine cowboys were responsible for smuggling massive quantities of cocaine into Miami, using a variety of methods including boats, planes, and even submarines. The trade was incredibly lucrative, with some estimates suggesting that the cocaine cowboys were making tens of millions of dollars per year. However, the era was also marked by violence and corruption, as rival drug dealers and smugglers battled for control of the trade. The Miami cocaine cowboys were also known for their excess and flamboyance, with many of them living lavish lifestyles and flaunting their wealth. The era came to an end in the late 1980s, as law enforcement began to crack down on the cocaine trade and many of the major players were arrested or killed.
