Reflection Paper: Addiction and Theories Ksir, C., Hart, C., Ray, O. Drugs, Society and Human Behavior , Twelfth Edition
Read Chapter 2 of the text, note the definitions and the major theories about how drug use leads to drug abuse/addiction. What is your favorite theory(s) of Addiction? Why do people become addicted to alcohol, tobacco and other drugs (ATOD)? Write a definition of addiction/dependency: Nature of addiction/dependency – etiology: what happens to a person who is addicted/dependent on ATOD (See also chapter 1 “Drug Dependence†and “Stages of Drug Dependenceâ€; Chapter 2 “The vicious Cycle of Drug Addiction). Bio-Psycho-Social Model: write your favorite explanations of why someone might become addicted to AOD, based on specific theories in each of the following categories: Biological causes/factors of addiction/dependency, Psychological causes/factors of addiction/dependency, Social causes/factors of addiction/dependency. The Biopsychosocial Approach was developed at Rochester decades ago by Drs. George Engel and John Romano and emphasizes understanding human health and illness in their fullest contexts, considering biological, psychological, and social factors and their interactions in health and illness. To apply this approach to clinical practice, the clinician should recognize that relationships are central to health care, use self-awareness as a diagnostic and therapeutic tool, elicit the patient’s history in the context of life circumstances, decide which aspects of biological, psychological, and social domains are most relevant, and provide multidimensional treatment.

Introduction
Understanding addiction requires an exploration of various theories that explain why individuals develop dependencies on substances such as alcohol, tobacco, and other drugs (ATOD). Addiction is a complex, multifaceted phenomenon characterized by compulsive drug seeking and use despite adverse consequences. This paper will define addiction, examine the major theories that explain its etiology, and explore the biological, psychological, and social factors contributing to addiction through the lens of the biopsychosocial model.
Definition of Addiction/Dependency
Addiction, often synonymous with dependence, refers to a chronic disorder characterized by an individual's compulsive engagement in drug use despite harmful consequences. It encompasses physiological dependence—marked by tolerance and withdrawal—and psychological
dependence—cravings or a perceived need for the substance (American Psychiatric Association, 2013). Dependency implies a state in which the individual's physiological or psychological state is altered, leading to difficulty in cessation without experiencing adverse symptoms or cravings.
Major Theories about the Pathway from Drug Use to Addiction
The transition from casual drug use to addiction has been explained by several prominent theories. The Disease Model views addiction as a chronic, relapsing brain disease characterized by neurochemical changes in the brain's reward system (Leshner, 1997). The Moral or Choice Model attributes addiction to moral weakness or poor self-control, emphasizing individual responsibility (Marlatt & Gordon, 1985). The Psychosocial Model emphasizes environmental influences and social context, including peer pressure, trauma, and socioeconomic factors (Miller & Rollnick, 2013). Lastly, the Biological Perspective focuses on genetic predispositions and neurobiological alterations that predispose certain individuals to addiction (Kreek et al., 2005). In my opinion, the disease model resonates most because it emphasizes the neurobiological changes that explain persistent substance use despite harm (Koob & Volkow, 2010).
Why Do People Become Addicted?
Many factors influence addiction development, including genetic vulnerability, psychological predispositions, and social environment. For example, some individuals have genetic variants that affect neurotransmitter systems related to reward and impulse control, increasing their susceptibility (Kreek et al., 2005). Psychological factors such as trauma, stress, and mental health disorders can predispose individuals to self-medicate with substances (Khantzian, 1985). Social influences, including peer pressure, cultural norms, and poverty, play a significant role in initiation and maintenance of drug use (Miller & Rollnick, 2013). The interplay of these factors demonstrates the complex etiology of addiction, affirming the importance of a multidimensional approach.
Biopsychosocial Model of Addiction
Biological Causes/Factors
Biologically, addiction involves neuroadaptations within brain reward pathways, primarily involving the mesolimbic dopamine system (Koob & Volkow, 2010). Chronic drug use leads to changes in neurotransmitter levels, receptor sensitivities, and neural circuitry, which foster tolerance and dependence. Genetic predispositions also influence how individuals metabolize drugs and respond to their effects,
contributing to variability in addiction risk (Kreek et al., 2005). For instance, variations in genes related to dopamine transporters or opioid receptors can modify susceptibility, highlighting the biological underpinnings of addiction (Barke et al., 2018).
Psychological Causes/Factors
Psychological factors include mental health disorders such as depression, anxiety, or personality disorders that may increase vulnerability to addictive behaviors (Khantzian, 1985). Additionally, coping mechanisms and emotional regulation deficits can lead individuals to seek relief via substances (Higgins & Silverman, 2013). The cognitive-behavioral perspective suggests that learned associations and reinforcement from drug use reinforce addiction, creating a cycle of dependence (Marlatt & Gordon, 1985). Also, impulse control issues and impulse-driven personality traits are associated with higher risk (Moeller et al., 2001).
Social Causes/Factors
Social determinants significantly influence the likelihood of developing addiction. These include socioeconomic status, cultural norms, family dynamics, peer influences, and exposure to environments with high drug availability (Miller & Rollnick, 2013). Social stressors such as unemployment, discrimination, and trauma also contribute to the initiation and continuation of substance use (Sinha, 2008). Support systems and community resources can act as protective factors or risks, emphasizing the importance of social context in addiction etiology.
The Biopsychosocial Approach to Addiction
The biopsychosocial model integrates biological, psychological, and social factors, emphasizing their dynamic interaction. This comprehensive perspective recognizes that addiction is not solely a biological malfunction but also influenced by mental health, behavior, environment, and social support. This model encourages clinicians to evaluate the patient's biological vulnerabilities, psychological state, and social context, facilitating personalized, multidimensional treatment approaches. For example, pharmacotherapy might address neurochemical imbalances, while psychotherapy can modify cognitive patterns, and social interventions can improve environmental stability.
Conclusion
In conclusion, understanding addiction through the lens of different theories and the biopsychosocial model underscores the multifaceted nature of this disease. Recognizing the interplay of biological,
psychological, and social factors allows for more effective prevention and treatment strategies. The disease model's emphasis on neuroadaptation, supported by psychological resilience and social support, provides a comprehensive framework for addressing addiction. Future efforts should focus on integrating these perspectives to develop holistic interventions tailored to individual needs.
