What is drug addiction?
Drug addiction, also called substance dependence or chemical dependency, is a disease that is characterized by a destructive pattern of drug abuse that leads to significant problems involving tolerance to or withdrawal from the substance, as well as other problems that use of the substance can cause for the sufferer, either socially or in terms of their work or school performance. More than 2.6% of people suffer from drug addiction at some time in their life.
The term dual diagnosis refers to the presence of both a drug-abuse or dependence issue in addition to a serious mental-health problem in an individual. Substance abuse or dependence unfortunately occurs quite commonly in people who also have severe mental illness. This is important given that people with a serious mental illness are far more at risk of engaging in violence, being incarcerated, or contracting infection with the human immunodeficiency virus (HIV). Individuals with dual diagnosis are also at higher risk of being noncompliant with treatment.
