When Michael Brown lost both his parents about six years ago, his drug addiction spun out of control. He spent all of his money on drugs and eventually lost his home. After staying with a friend for a while, he officially became homeless about a year and a half ago.

Since then, he's been sleeping in shelters and job hunting every day. But he realizes he won't get decent work until he can stay clean.

"You can go to all the rehabs, you can go to all the counseling, but if it's not in your heart, you're not gonna' do it -- and I made up my heart and my mind that this drug thing, I've got to beat it, because if I don't it's gonna beat me," he said.
