These are drug addicts mostly (alcohol or worse), arresting them accomplishes nothing, buying them a new house accomplishes nothing, they will use until they die or quit, all on their own. Nobody can do it for them.
If you want less deaths, legalize. You can prevent a lot of overdoses and death, and use the profits for drug treatment and education. Everyone should have to look at this as a kid, this should be a fundamental part of school.
