Mike Youngblood was Black Mafia and went away for drugs in the 80s (he was actually part of Martarano's drug operation) and I also have heard and even seen it written that Mike Youngblood was a major associate of Sal Testa. Whether the two were directly engaged in drug dealing or not I cannot tell you for sure. Mike Youngblood and the Black Mafia were also into Numbers and some gambling as well so the association between the two could have been a number of things. Most likely though, anything drug related with Salvie was loaning him money with points to finance his drug deals, which basically everyone in the Scarfo Family was doing at that time. It's how they were able to skirt the drug rule within a Scarfo even though it was a joke because the only difference was they were just getting someone else that wasn't in the Family to physically handle the drugs. Joe Punge even got caught with Mike Madgin (who was a rat) financing meth deals and even getting a cut of drug operations in addition to the extent where he would get referral fees for connecting drug dealers with suppliers, etc. If that drug rule was actually enforced then Raymond Martarano should never have been made let alone able to live...
