Animal models only show compulsive behavior in bad circumstances. Put a rat in an empty cage, it will misuse drugs. Put it in a cage full of other rats and things to dig in and climb on, and it will not misuse drugs.

So if this model is valid for humans, then it means that addicts are unhappy about their circumstances. Modern society is making some people so unhappy that they turn to drug misuse. Modern society is sick. It is making people feel lonely and isolated. We need to heal our society collectively. Spread the love.
