instruction: Given this paragraph, how much control of the world's cocaine market did the Cali Cartel have at its peak?
context: The Cali Cartel (Spanish: Cartel de Cali) was a drug cartel based in southern Colombia, around the city of Cali and the Valle del Cauca. Its founders were the brothers Gilberto Rodríguez Orejuela, Miguel Rodríguez Orejuela and José Santacruz Londoño. They broke away from Pablo Escobar and his Medellín associates in 1987, when Hélmer "Pacho" Herrera joined what became a four-man executive board that ran the cartel.
  
  At the height of the Cali Cartel's reign from 1993 to 1995, they were cited as having control of over 80% of the world's cocaine market and were said to be directly responsible for the growth of the cocaine market in Europe, controlling 80% of the market there as well. By the mid-1990s, the leaders of the Cali Cartel's multibillion-dollar international drug trafficking empire were operating a US$20 billion a year global criminal empire.
response: At the Cali Cartel's peak from 1993 to 1995, they controlled over 80% of the world's cocaine market.
