It's the causes, not the dependent person, that must be corrected. That's why I see the United States' War on Drugs as being fought in an unrealistic manner. This war is focused on fighting drug dealers and the use of drugs here and abroad, when the effort should be primarily aimed at treating and curing that causes that compel people to reach for drugs.
The treatment must fit the malady and the malady is not alcoholism or addiction, or addictive drugs and alcohol. Once the correct cause is diagnosed, healing will take place and hoped-for cure will come about.
Whether the underlying cause of your dependency is a chemical imbalance, unresolved events from the past, beliefs you hold that are inconsistent with what is true, an inability to cope with current conditions, or a combination of these four causes, know this: not only are all the causes of dependency within you, but all the solutions are within you as well.
The punishment approach and bad consequences approach to treatment is the kind of thinking that is prevalent in every residential substance abuse treatment center in the United States of which I'm aware.
It takes a strong person to stand up to his or her fate and overcome the obstacles that stand in the way of freedom and success, but I believe in you.
