The 37-year-old actor made the confession while filming BBC Three documentary 'Russell Brand: From Addiction to Recovery' due to air this month, reported Daily Star.
"This is when you know it's a disease. It doesn't matter that I was in that flat (apartment) in Hackney and now I'm in the Savoy (Hotel). I'm jealous of me then. It doesn't make a difference to me. The money, the fame, the power, the sex, the women - none of it. I'd rather be a drug addict," Brand said in the documentary.
However, Brand said he is well aware of the negative impact the toxic substances had on him and his loved ones.
"Heroin is a greedy drug, it'll take everything. First it'll take your money. Then it'll take your friends, your family, your car, your house."
