On a recent podcast Joe Hogan was talking about a friend that was all fucked up on adderall and needed rehabilitation. It may be Goldie.
Or it may be coke.
But, Dana and Goldberg have been calling it a "health" problem on Twitter. If it were something else, they wouldn't be so secretive I don't think.
Goldberg needs something to be so high energy and annoying, I bet it is more than just Redbull.
