Area of Science:

  • Neuroscience and behavioral science

Background:

  • The traditional addiction model attributed substance use disorders to ignorance, unhappiness, or lack of opportunity.
  • Physical dependence was considered the primary driver of continued use despite negative consequences.

Purpose of the Study:

  • To introduce and elaborate on the new reward-based paradigm of addiction.
  • To contrast this new model with the older view of addiction.

Main Methods:

  • Conceptual analysis and synthesis of existing addiction research.
  • Comparison of the older and newer theoretical frameworks of addiction.

Main Results:

  • The new paradigm emphasizes the powerful brain reward associated with addictive behaviors.
  • Potential addicts actively seek this reward, often disregarding risks.

  • Physical dependence and withdrawal are considered secondary to the primary role of reward.

    • Conclusions:

    • Addiction is fundamentally driven by the brain's powerful reward system.
    • This new understanding necessitates a shift in addiction prevention, treatment, and policy.
    • Medical interventions, including those with controlled substances, must align with this reward-centric model.
