I have never seen any proof, or even strong indication, that Castellano took any money from drugs off Conte. Or off anyone else. I think that is said about him as way to make him not seem like glamorous, or noble Mafia boss. They even had his home bugged, yet nothing on him taking drug money off Conte. I looked though everything I could on matter there is no evidence of it at all. I think it is a myth that has grown, or that people who feel worried that Mob may get glamorized perpetuate.
Gravano testified to that very thing, i.e. how after the takeover Gotti had Gravano approach Conte and demand the "same arrangement" from Conte's drug operation that he had with Castellano. Now, if you want to believe Gravano was lying, go ahead, but I don't think so.
