The National Institute on Drug Abuse defines addiction as a, “chronic, relapsing brain disease that is characterized by compulsive drug seeking and use, despite harmful consequences. From this it considers addiction as a brain disease because drugs change the brain - they change its structure and how it works.” Changes in the brain can be long lasting as well as having the possibility of leading to progress the harmful behaviors demonstrated in people who abuse substances.. In the past decade, there has been an escalating awareness by the scientific community that substance abuse disorders are medical disorders with biologic, chemical, and environmental causes. Where as in the past substance abuse and addiction had been considered solely behavioral problems, there is now a consistent body of evidence that these disorders actually have more extensive effects and can worsen preexisting medical conditions, temporarily mimic certain psychiatric disorders, and cause other medical problems. “Moreover, substance use disorders are common: the lifetime prevalence of these syndromes, including alcoholism, is over 20% for men and about 15% for women, with young and middle-aged persons most heavily affected. On any given day, the average clinician is likely to see patients with substance use disorders and related problems.” (Moeller)
Among the many definitions of addiction, there is yet another that defines it from a biochemical perspective. Professor of Psychology and author Harry B. Milkman defines addiction as " self-induced changes in neurotransmission that result in social problem behaviors." This definition touches on the psychological, biochemical and social aspects of addictive processes. “It is not limited specifically to substance...

...y Information, “Clinical and laboratory observations have converged on the hypothesis that addiction represents the pathological usurpation of neural processes that normally serve reward-related learning.” The major substrates of persistent compulsive drug use are hypothesized to be molecular and cellular mechanisms that underlie long-term associative memories in several forebrain circuits (involving the ventral and dorsal striatum and prefrontal cortex) that receive input from midbrain dopamine neurons.
Addiction is a disease that may affect the psychology of the brain but that is due to the chemical effects of the drug abuse on the human body. Though in my opinion, it seems you cannot have one without the other, since the assignment was to chose one side over the other I would say that the cause of addiction is mostly physiological as opposed to psychological.

The biopsychosocial model of addiction theorizes that crossing biological, psychological and social and systemic properties are essential features of health and
As illustrated the model of drug abuse and the theories behind addiction are varied. There is no concrete reason for one person who drinks to become alcohol dependent versus the person who does not. Several factors contribute to why a person begins drinking and why they continue to do so despite reasons to stop. The case history exhibits a client with many risk factors associated with alcohol use and dependence.

George F. Koob defines addiction as a compulsion to take a drug without control over the intake and a chronic relapse disorder (1). The Diagnostic and Statistical Manual of Mental Disorders of the American Psychiatric Association defined "substance dependence" as a syndrome basically equivalent to addiction, and the diagnostic criteria used to describe the symptoms of substance dependence to a large extent define compulsion and loss of control of drug intake (1). Considering drug addiction as a disorder implies that there are some biological factors as well as social factors.
Addiction is defined as a chronic, relapsing brain disease that is characterized by compulsive drug seeking and use, according to the National Institute on Drug Abuse. Addiction is normally thought of as drug abuse and alcoholism but people can also be addicted to things such as gambling and sex as well. The controversy on if addiction is a disease or a choice is a continuous debate. Everyone has an opinion on this topic, one side believes it’s a disease, while the other believes it is a choice. Although addiction has been assumed to be a lack of willpower and a weakness, addiction is actually a complex disease that changes the wiring of the brain. Addiction is a brain disease expressed in the form of compulsive behavior (Leshner.) Both devolping
The most commonly abused substances are Nicotine, Inhalants, Alcohol, Cocaine, Amphetamines, Prescription medications, Heroin, Ecstasy and Marijuana. 1a(National Institute on Drug Abuse, 2011) Initially, a person may find themselves using substances voluntarily and with confidence that they will be able to dictate their personal use. However, over the period of time that drug use is repeated, changes are taking place throughout the brain, whether it is functionally or structurally. Drugs contain chemicals that enter the communication system of the brain and disturb the way in which nerve cells would typically send, receive, and process information. The chemicals within these drugs will cause a disruption to the communication system by either imitating the brain’s natural chemical messengers or by over-stimulating the brains “reward system” by sending mass amounts of dopamine. As an individual prolongs his or her use of these substances, they may develop an addiction.
According to Leshner, drug addiction is a chronic brain disease that is expressed in the form of compulsive behaviors (Leshner, 2001). He believes that drug addiction is influence by both biological, and behavioral factors, and to solve this addiction problem we need to focus on these same factors. On the other hand, Neil Levy argues that addiction is not a brain disease rather it is a behavioral disorder embedded in social context (Levy, 2013). I believe, drug addiction is a recurring brain disease that can be healed when we alter and eliminate all the factors that are reinforcing drug addiction.
Many people dislike the term ‘addiction’ in relation to drugs or other substances, particularly as it infers that a person is powerless over their use of a particular drug or in some circumstances, a number of substances. Whilst others maintain it is this powerlessness that is the foundation of diagnosis and treatment – that treatment is not possible without recognition of addiction itself as the ‘problem’ being addressed. The professional and public perception of addiction is complicated. There are many approaches and models to explain addiction, the role of the addict, and their environment. This essay will compare and contrast two of these approaches, the medical/disease and the social model. Initially this essay will describe the origins of each model, and follow by explaining their respective strengths and weaknesses, and finish with an overview of the key differences between them. This essay will conclude by demonstrating that a holistic approach, and a cross-pollination of these models is the most successful approach to treating addicts. As is the case for all diseases, there are multiple treatment options, and as ever person is different, the results in each individual cannot be predicted.
Drug abuse and addiction are issues that affect people everywhere. However, these issues are usually treated as criminal activity rather than issues of public health. There is a conflict over whether addiction related to drug abuse is a disease or a choice. Addiction as a choice suggests that drug abusers are completely responsible for their actions, while addiction as a disease suggests that drug abusers need help in order to break their cycle of addiction. There is a lot of evidence that suggests that addiction is a disease, and should be treated rather than punished. Drug addiction is a disease because: some people are more likely to suffer from addiction due to their genes, drug abuse brought on by addictive behavior changes the brain and worsens the addiction, and the environment a person lives in can cause the person to relapse because addiction can so strongly affect a person.
Substance use disorders and mental health disorder can be challenging for human services professionals as well as for the individual; combined these disorders together and treatment can be seemingly insurmountable. The complexity of the disorders separately, as well as together raises the need for treatment that looks at the whole person not just a set of symptoms. The debate between which disorder came first is useless at helping to resolve the problems that are currently occurring with these complex disorders. According to Stevens & Smith (2013), over five million adults have a co-occurring disorder. With such high number it’s no surprise that the amount of money that is spending on co-occurring disorders is staggering and far exceeds that
So, it is clear that addiction is all around us and can attack anyone of us at any given time. Even studies conducted show that people neglect to speak around their dependency for two primary reasons. Foremost, because people do not comprehend, or they bear a total misconception to their addiction, that they do not realize that addictions can be critical to their overall wellness. Moreover, second, many people believe being an addict will never happen to them, but, in reality, most addictions start off as simple little habits. Such as starting with one drink after dinner and before you know it you are drinking several drinks a day. However, one does not opt to be addicted to a substance, because addictions are physical defects in the brain, a disease, and not one’s choice.

There are many assumptions of why an individual may use different substances and perhaps go from a “social” user to becoming addicted. Understanding the different theories models of addiction many help in the process of treatment for the addict. Although people in general vary in their own ideologies of addiction when working as a clinician one must set aside their own person beliefs. Typically as a clinician it is best for the client to define how they view their addiction and their view may encompass more than one of the five theories. Some theories suggest genetic and other biological factors whiles others emphasize personality or social factors. In this study three theories are defined and given to three different people with different cultural backgrounds, different ideologies, different experiences, and most importantly different reference point of addiction.
