One of the first big connections between the italian/jewish mob and the mexican's was somewhere around late 30's or early 40's.Story goes that Meyer Lansky,Benjamin Siegel,Moe Dalitz and Harry Tietlebaum with the help of the Los Angeles crime family,worked on expanding drug trafficking operations in Mexico and also finding other alternative routes.A lucrative heroin network had been established from drug traffickers based in Mexico City,from Los Angeles to major cities across the United States including New York,Philadelphia and Miami.They were dealing with Enrique Diarte,a Tijuana based Mexican narcotics trafficker.But back in thouse days Mexico had been producing lowgrade heroin for a number of years,they had never been able to produce the fine white powder demanded by the addicts.
