Addiction Is a Brain Disease 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. It is not uncommon to view drug addiction as a problem that is created and maintained by the drug addicts. Most of …show more content…
However, the article seems to be outdated since it was published more than fifteen years ago. In addition, Leshner seems to have committed red herring fallacy in his work. For example, he begins his article strictly discussing that addiction is a brain disease then he shifts the topic to war on cancer, and that we need to directly address all the vectors, the drug dealers, suppliers, in order to eliminate …show more content…
He argues that addiction is a behavioral disorder caused by the person’s social environment and the lack of resources. Levy believes that, most of the time, an addict does not have services or resources available in order to remove herself from “the environment” where drugs are found constantly. He also stated that most of these addicts are physically unfit since they are poorly nourished, and they are struggling with their own personal stress. Levy, in his article, highlighted that a person’s environment, his health, and the resources he has, play a crucial role in determining whether or not the person will abuse drugs. Levy’s arguments seem to hold a strong position concerning addiction and its causes. However, his arguments seem to contain ambiguous words which can leave readers wandering about the actual definition of the word, and also interrupt their reading. For instance, Levy argues that addiction can be defined as a disease only if it includes pathological deviations from “norms of brain function” (Levy, 2013). He also mentions claims like addiction can lead to some deficits that are “relatively minor”, and addiction can cause impairment only in “certain” social environments (Levy, 2013). These words, norms, minor, certain, can be viewed as ambiguous words since it can have more than one meaning. In addition, Levy, in his article, seems to contradict some of his
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.
In the eyes of the public, the word addict stirs up a negative image: a person of low moral character who willfully chooses to engage in questionable behavior. This image is perpetuated in the media; on a recent episode of E.R., the chief surgeon criticizes another doctor for allowing a heroin addict (who has been treated for an abscess) to exchange a dirty needle, explaining "we donât want these low-lives hanging around the hospital." The social stigma attached to addicts reflects the great gap that exists between scientific knowledge and public perception of addiction. Just as mental illness was viewed as a social problem instead of a medical issue until the last several decades, drug addiction continues to be seen as a character flaw instead of as the biological problem that it is.
Hari’s inconsistent biased information neglects the possibility of the negative outcome if governments around the world decide to decriminalize all of the make major contraband drugs. Study after study that Hari has done has shown, is that incarcerating addicts does not rehabilitate them but instead increases the risk in making in repeating the same mistake again, and criminalizing drugs does not make these substances disappear, instead, it makes them more dangerous. Hari exaggerates more on the information that he has researched in the text instead of explaining the importance of what he has shared to the readers. He explains how and why addicts become addicted to their substances is that of the lack of “bonding” that he or she in their environment. Hari argues that this is why some people can use drugs and alcohol and not become addicted while others cannot. To the people who have a connection to their environment don’t become addicts. Those who don’t have that connection to their environment is part of the small percentage of the population that is addicted to drugs or alcohol. Hari does not provide the science within the text that examines the whole meaning of addiction. In a blog post written by Dr.Derek Simon, a neuroscientist and graduate from University of Michigan with a PhD, who is studying neurobiological basis for drug addiction at Rockefeller University, writes that “Hari’s argument makes no mention of the
Understanding addiction is a complicated subject that inspires controversy and debate. Not only do people want to understand addiction because of the curiosity to understand human beings and human nature, but there are factors that go into the defining of addiction such as public policy and health care coverage. There are two theories that are on the opposite spectrum when it comes to addiction which include the “disease concept” and the “choice theory”. One defines addiction as a disease, something that is out of one’s control, while the other thinks of it as a choice or a moral deficiency that resides in a person. The consequence of this gap is the delay in gaining control over drug abuse. While the people who support the choice theory see
“This Neuroscientist Argues That Addiction Is Not a Disease and Rehab Is Bullshit” written by Neil Sharma. Marc Lewis argues how addiction is not a disease and rehab is ineffective.
Addiction is like all behaviours “the business of the brain”. Addictions are compulsive physical and psychological needs from habit-forming sustenances like nicotine, alcohol, and drugs. Being occupied with or involved in such activities, leads a person who uses them again and again to become tolerant and dependent eventually experiencing withdrawal. (Molintas, 2006).
(Page 11). This statement seems to be saying that because this topic is so controversial and not enough medical proof is available it has been given a generic name. It is true that drugs and alcohol can cause diseases, but does that make the addiction problem a disease? Perhaps this topic is so controversial because of the lack of knowledge or understanding of drug addiction. On a Website entitled “Addiction is a Chronic Disease,” the source was comparing diabetes and cancer to support their idea that drug addiction to is a chronic disease.
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 a term that has traditionally been used to refer to psychiatric syndrome that is caused by illicit drug use. Actually, addition is the only psychiatric condition whose symptoms are regarded as an illegal activity. In most cases, this term is described on the basis of drug use, which is the main focus of many research and treatment programs. Generally, drug addiction has significant negative effects on individuals using the drug and those around them such as family and friends. Family and friends are usually forced to watch their loved ones wilt away in illicit drug use. While addiction has traditionally been regarded as a psychiatric condition, there are numerous debates that have emerged on whether it’s a disease or merely an immoral act by a selfish individual. My standpoint is that addiction is actually a disease because of the observations I have made on how illicit drug use takes control of the addict. I have watched my brother battle prescription drug addiction and eventually passed away from an overdose at the age of thirty-two years. As a result, I believe that addiction is a disease because it changes the functioning of the addict’s brain. In essence, studies have demonstrated the effects of chemical substances on the brain and how addiction affects feelings, thoughts, and actions.
A disease is what happens in the body as a result of those choices. As has been noted, many people do believe addiction is a sign of weakness. While the first time may be by choice, once the brain has been changed and affected by addiction. Over time the addict loses substantial control over his or her initially voluntary behavior, and it becomes compulsive (Leshner.) In Marc Branch’s “Drug Addiction. Is It a Disease or Is It Based on Choice? A Review of Gene Heyman’s Addiction: A Disorder of Choice” he discusses and explains Gene Heyman’s opinions on rather addiction is a disease or not. Heyman argues that people do not choose to be drug addicts, rather they make choices that lead to their habit of addiction. Heyman however does not believe addiction is an actual disease. Many others argue that addiction is not an actual disease because people can overcome the addiction without help or treatment. On the other hand, in Alan Leshner’s “Addiction Is a Brain Disease” he declares that addiction is an actual disease and explains “using drugs repeatedly over time changes brain structure and function in fundamental and long-lasting ways that can persist long after the individual stops using them”

Addiction has been a part of my life for as long as I can remember, from my earliest memories of my father, until now as I am a licensed professional in the field of addiction as well as a person in long term recovery myself.
The term addiction originates from the Latin words for both “bound to” and “enslaved by”; a fitting ideology for those experiencing the symptoms of addiction through a loved one, or even personally. Addiction ranges from a number of categories. For instance, food, sex, gambling, alcohol, and drugs can give rise to addiction, among numerous others. Descriptive of all these examples, addictive substances are characterized by two principles: reinforcing stimuli and rewarding outcome. Addiction is a medical condition distinguished by biological and psychological factors. These factors, after repeated exposure of a rewarding stimuli, give rise to changes in learning and memory. However, addiction has not always been perceived as a medical condition. In the 1900’s, addiction was not discerned as a
There are many people in the world today that has had or currently has a drug addiction. Most people usually know what the consequences of taking a drug is, but they usually don’t think about that at the time. When people start taking drugs they don’t think about what is going to happen or even care what could happen. All they care about is that next high. A recent statistic states that 23.9 million Americans age adolescents and up have participated in using drugs in the last month.
