Nothing for Dre to market and even Trump wasn't foolish enough to spend his money promoting the vodka with his name, and that was when the company actually had some a strong balance sheet and good sales.
As far as the Dr. Dre hype. A lot of people in the hip hop community are saying that his Detox album is just a huge publicity stunt to sell his topless sparkling vodka and liquor line, which is also a joint venture with 50 Cent.
