In his memoir, "Flavor Flav: The Icon", he talks about his addiction and the hold it had on him.  He was spending $2,600 per day totaling 5.7 million dollars within 6 years.  

When asked how did he get clean, he said, "I went out to California in the middle of 2003 and I changed my people, places and things.  I knew that in order for me to do that and be successful, I had to leave all of that behind me. I had to because me being a major celebrity, everything that I do, word will travel. I didn’t want to build a bad reputation in other states. I wanted to leave all that stuff in New York. That’s what really helped me get clean by me not wanting to build up a reputation of me going through neighborhoods buying drugs."

Really Flavor?  Are you sure you quit because you looked more and more cracked out…just saying… WOOOOOOW
