In a recent interview with XXL he said he was clean... he said he got really bad in '05-'06 and part of '07... but since then he has cleaned up and is working out with the Detroit Pistins trainor to get in shape... He said it really fucked him up... I think he had a serious pill problem... but he didnt say what drugs he was doing...
and who knows if Dre even smokes the ganja anymore? Dude is like 45 or something now, isnt he?
