I'm sorry, but the idea that having a place to sleep is enough to save a life is sorely mistaken. A third of chronically homeless people have at least a serious mental health issue and those don't go away. Likewise substance abuse is a hard thing to kick EVEN WITH A HOME. It's doubly so these days when drugs are routinely cut with fentanyl, designer drugs, and worse. A good friend of mine died three years ago very much homed, but almost totally unable to find meaningful, quality, and lasting treatment. In the end after a DECADE clean someone abused her, tricked her, and she was gone three months later.
PUTTING PEOPLE UNDER A ROOF IS NOT ENOUGH.
