It seems like every major mobster since the 70's was either directly involved with drugs, was accepting profits made from drugs, or was close enough to someone selling drugs that they could he considered part of the conspiracy.

How does it work exactly? These guy's cant possibly be out dealing drugs on their own right? I assume they use a massive amount of cash, buy a massive amount of product, and then sell it to dealer's or associates to distribute for them? Am I guessing right here?

You just read on guys like Gotti or DeMeo dealing drugs, or pretty much anyone from their generation on.. How do they do it? They cant possibly be out on a corner or in a dinner or bar or restaurant openly selling the booger sugar or H right?
