Your comment illustrates a large part of the problem. If society believes addiction is mostly a willpower problem, then effective services to help address it won't exist.
That said, most people don’t become addicts in a vacuum. Many people become addicts only because a life under the influence beats their life otherwise. Unfortunately it’s a lot harder to fix someone’s life than it is to get them sober. But the poor sober life is, in my opinion, the actual underlying condition which leads to addiction. We don’t really have a framework for treating that as a society nor through the medical system.
