Extensive data shows that drug addiction rehab equally effective as treatment for most other similarly chronic medical conditions. It is important for those entering treatment to understand that addiction indicates an underlying behavior pattern with deeply emotional roots, and rehab treatment programs are also focused on dealing with these emotional issues in addition to stopping the use of drugs. Successful rehab programs focus on both the emotional and physical issues associated with addiction. Individuals in treatment must examine the behaviors that promoted drug use and change those behavior patterns in order to promote recovery. Because addiction is a chronic disorder, the ultimate goal of successful, long-term recovery requires dedication to sustained treatment methods, such as support groups and individual therapy.
