I know V and Q both get the drugs from Buddy. But, where does a junkie like Buddy gets the prescription drugs, that can only come from a pharmacy a hospital, or lab? Either Buddy robs one of those every week, or he knows someone that has access to the warehouse of one of those places, and is able to steal drugs and remain unnoticed. And that's not easy. That's why I though that maybe it's the same mafia the one that is running the prostitution ring and the drugs ring. Maybe is a net that extends across several colleges or something like that, because I don't think the profit in B&R from four of five girls doing blowjobs in bathrooms and selling some weed and pills to other students justifies the risk. Or maybe DPC just didn't though in that.
