Louis Casanova is playing cards with a friend on the back deck of a recovery house in Philadelphia's northern suburbs.
He's warm and open as he talks about his past few years. The guy everyone calls Louie started using drugs like Xanax and Valium during his freshman year of high school. At age 18, Casanova turned to heroin. About two years later, the rehab shuffle began.
"I relapsed and then I was just getting high. And then I went to treatment again in February of 2015," he says. "Then I relapsed again and went back to treatment."
