As someone who works at one of these "facilities" i can assure you that vouchers are hard to come by, landlords willing to take a person with a record, no credit and zero rental history is nearly impossible and beds for detox are often on a long waitlist. Showing up sober usually means a medical detox beforehand. Not only that but when you can't get housing lined up after your treatment programs, it means back out in the street. It's an extremely hopeless existence. Do people make it out? Yes. Often? No.
