The seven models of addiction include the Biopsychosocial Model, the Disease Model, the Genetic Model, the Behavioral Model, the Neurochemical Model, the Developmental Model, and the Relapse Model. Each model views addiction from a different perspective, and together they provide a comprehensive understanding of why people become addicted to drugs. The Biopsychosocial Model takes into account biological, psychological, and social factors that contribute to addiction. The Disease Model views addiction as a chronic illness with physical, psychological, and social components. The Genetic Model focuses on the role of genetic factors in addiction. The Behavioral Model looks at how addiction develops through a pattern of behavior. The Neurochemical Model examines the role of neurotransmitters and other brain chemicals in addiction. The Developmental Model looks at how addiction develops over time and how it may be impacted by developmental stages. Finally, the Relapse Model looks at how addiction can be maintained despite attempts to quit, and how relapse is part of the addiction cycle.
