  12. Two Disease Models of Addiction
    • Susceptibility models: Initial drug use + inherited susceptibility to uncontrolled drug use --> repeated drug use --> loss of control
    • Exposure models: Initial drug use --> repeated drug use --> altered brain function --> loss of control
  13. 4 models of drug addiction: physical dependence model, positive reinforcement model, incentive-sensitization model, opponent-process model
    • Physical dependence model: focus on withdrawal symtpoms
    • Positive reinforcement model: focus on rewarding properties of drugs/craving; rat experiments where they keep self-administering drugs
    • Incentive-sensitization model: focus on distinction between "wanting" (incentive salience) and "liking" (euphoria)
    • Opponent-process model: who cares

    • Allostasis: when you become addicted, you shift to allostasis; changing set point, compromised equilibrium, etc...
