If you ask me the main guys were like Detriot's Frank Coppola who had connections to Sicilian dope peddlers such as Ugo Caneba who in turn had some major contacts to Corsican drug traffickers with laboratories in Marseilles such as the Arnaci brothers. Large quantities of opium or morphine were diverted into heroin in the Schapparelli Pharmaceutical Co., in which Luciano was also a partner.
