Miami's cocaine trade began to take off in the 1970s, as Colombian cartels began to establish themselves in the city. The trade was fueled by demand from wealthy Americans and Europeans, and soon Miami became a major hub for cocaine trafficking. The era was marked by brutal gang wars, as rival cartels and gangs fought for control of the trade. One of the most notorious figures of the era was Griselda Blanco, a Colombian cartel leader known as the 'Queen of Cocaine.' Blanco was responsible for numerous murders and kidnappings, and was eventually arrested and sentenced to prison. The cocaine trade also had a corrupting influence on law enforcement, with many officers and politicians accepting bribes and turning a blind eye to the trade. The era came to an end in the late 1980s, as law enforcement began to crack down on the trade and the cartels began to fragment. The impact of the cocaine trade on Miami was lasting, with many residents still remembering the violence and fear that gripped the city during that time.
