It's a misallocation of resources for the state to try to save adults who don't want saving. If a drug addict doesn't specifically request help to beat their addiction, it would be simpler and cheaper for the legal system to give them as much of the drug as they want. They'll either become functional addicts or just finish their slow-motion suicides. Either is less wasteful than forcing them into rehab or incarceration.
