That a good point but that cost is for the addicts who get care. How many will not seek care? How many will become homeless? Not saying homelessness is a major cost but is a cost. It's also blight and a huge health issue. It's a concern. Do we then scoop them up and force them into treatment? I think it's safe to say that along with mental illness and alcohol abuse the biggest cause of homelessness is drug addiction. And how many of those released from incarceration will have nowhere to go? How many of them will end up on the streets? Of course it's a VERY complicated issue and why we, as a society, have turned a blind's eye to it.
