I don't think it's necessary for the camorra to turn to the Calabrians they have always had good connection in the coke business since the Sicilian Mafia never was involved only heroin untill the 90s with the Cuntrera-Caruanas and others.
sicilian mafia was and it is still involved in cocaine trafficking, although currently less than camorra and ndrangheta
the biggest single seizure ever of cocaine in italy (5,5 tons) was imported by sicilian mafia in 1994, by the caruana-cuntrera's
