The entire reason for the "no drugs" policy in the mafia is because the American/Italian mafia controlled most of the heroin TRAFFICKING on earth, and didn't want pissant $ attention bringing down their global network.

Its not coincidence that the entire leadership from Genovese to Riina across the world was involved in this.

The American mafia pretends the Cuba thing was about Castro and gambling and casinos but the reality is that Castro changed the entire drug trafficking landscape and forced many traffickers now to use Mexico > US instead of Cuba > US.

You may notice the Cubans got cut out of the global cocaine trade and now the Mexicans control almost all cocaine moving into America. That was another result of Castro locking down his country when Bautista had everything available if you could pay $

Once the Cuban path was shut, the Mafia focused most of its attention on bringing product in over the NY/Canada border and therefore you saw the Cotroni's etc and the motorcyle gangs working together to insure this. People like Badalementi were still moving tons of product via South America into the US until they came into conflict with 'other traffickers', in Badalementi's case it was more complex than that having problems with the Italian mafia itself.

The consequence to this was the American mafia does not control the cocaine trade in the way they do the heroin trade.

It is still in existence today as the mafia pays their political and media connections to complain 24/7 about the southern border while bringing entire states full of coke and heroin over the northern one.
