Sure but their premise is that addiction comes from life problems. Thats like saying “no pill can cure depression. - you’ll still have all the same problems.”

Depression is its own thing, not a reaction to life problems. Addiction is much the same. It even has hereditary components, like depression does.

In fact I would posit that a lot of homelessness is caused by drug addiction. At least as much as the other way around if not more.
