Here's something about the Luciano's release and the heroin route...

In 1946 American military intelligence made one final gift to the Mafia -they released Luciano from prison and deported him to Italy, thereby freeing the greatest criminal talent of his generation to rebuild the heroin trade. Appealing to the New York State Parole Board in 1945 for his immediate release, Luciano's lawyers based their case on his wartime services to the navy and army. Although naval intelligence officers called to give evidence at the hearings were extremely vague about what they had promised Luciano in exchange for his services, one naval officer wrote a number of confidential letters on Luciano's behalf that were instrumental in securing his release.Within two years after Luciano returned to Italy, the U.S. government deported over one hundred more mafiosi as well. And with the cooperation of his old friend, Don Calogero, and the help of many of his old followers from New York, Luciano was able to build an awesome international narcotics syndicate soon after his arrival in Italy.
The narcotics syndicate Luciano organized after World War It remains one of the most remarkable in the history of the traffic. For more than a decade it moved morphine base from the Middle East to Europe, transformed it into heroin, and then exported it in substantial quantities to the United States-all without ever suffering a major arrest or seizure. The organization's comprehensive distribution network within the United States increased the number of active addicts from an estimated 20,000 at the close of the war to 60,000 in 1952 and to 150,000 by 1965.
After resurrecting the narcotics traffic, Luciano's first problem was securing a reliable supply of heroin. Initially he relied on diverting legally produced heroin from one of Italy's most respected pharmaceutical companies, Schiaparelli. However, investigations by the U.S. Federal Bureau of Narcotics in 1950-which disclosed that a minimum of 700 kilos of heroin had been diverted to Luciano over a four-year period-led to a tightening of Italian pharmaceutical regulations. But by this time Luciano had built up a network of clandestine laboratories in Sicily and Marseille and no longer needed to divert the Schiaparelli product.
Morphine base was now the necessary commodity. Thanks to his contacts in the Middle East, Luciano established a long-term business relationship with a Lebanese who was quickly becoming known as the Middle East's major exporter of morphine base-Sami El Khoury. Through judicious use of bribes and his high social standing in Beirut society,El Khoury established an organization of unparalleled political strength. The directors of Beirut Airport, Lebanese customs, the Lebanese narcotics police, and perhaps most importantly, the chief of the antisubversive section of the Lebanese police,protected the import of raw opium from Turkey's Anatolian plateau into Lebanon, its processing into morphine base, and its final export to the laboratories in Sicily and Marseille.
After the morphine left Lebanon, its first stop was the bays and inlets of Sicily's western coast. There Palermo's fishing trawlers would meet ocean-going freighters from the Middle East in international waters, pick up the drug cargo, and then smuggle it into fishing villages scattered along the rugged coastline.
Once the morphine base was safely ashore, it was transformed into heroin in one of Luciano's clandestine laboratories. Typical of these was the candy factory opened in Palermo in 1949: it was ]eased to one of Luciano's cousins and managed by Don Calogero himself.The laboratory operated without incident until April 11, 1954, when the Roman daily Avanti! published a photograph of the factory under the headline "Textiles and Sweets on the Drug Route." That evening the factory was closed, and the laboratory's chemists were reportedly smuggled out of the country.
Once heroin had been manufactured and packaged for export, Luciano used his Mafia connections to send it through a maze of international routes to the United States. Not all of the mafiosi deported from the United States stayed in Sicily. To reduce the chance of seizure, Luciano had placed many of them in such European cities as Milan, Hamburg, Paris, and Marseille so they could forward the heroin to the United States after it arrived from Sicil concealed in fruits, vegetables, or candy. From Europe heroin was shipped directly to New York or smuggled through Canada and Cuba.
