It is a primary disease, not a symptom of some other underlying cause. Chemical dependency causes the related problems that occur in the user's or drinker's life. The exact cause remains unknown, but it is not causes by lack of willpower, weakness of character, or some flaw in a person's moral structure. It is impossible to predict who will become dependent when exposed to using drugs or alcohol. Due to the ever-present availability of and exposure to drugs and alcohol in our society, evidence is clearly showing that anyone who can become dependent, in all probability, will become dependent.
Chemical dependency is predictable and progressive.
Untreated, it will almost always get worse. However, dependency can be arrested and will remain so as long as there is abstention from mood-altering chemicals. Relapse is an ever-present danger. Recovery is a lifelong commitment. Chemical dependency is fatal.
