Chances are if you are addicted to one substance, especially if it has become a psychological dependence, abstinence from all mood and mind altering substances are the only way to go. All mood/mind altering substances affect the same area in the brain and the brain can not distinguish between the substances. So what happens is you stop smoking marijuana and start drinking and sooner or later you become psychologically/physically dependent on the new substance. This is cross addiction.
