The process of addiction has a chemical component that takes place in the addict’s brain as well as a behavioral component that is observable through the addict’s actions. Addiction therefore always has an aspect of change in the brain chemistry of an individual. A combination of factors including brain chemistry, drug chemistry, social interactions and thought processes combine to create the condition referred to as addiction (Doweiko, 2011).

The abstinence centered model uses a detoxification therapy approach to get the individuals and keep them in a drug free state.
