Biological Model Of Addiction

In 1960 E.M. Jellinek a scientist, was credited for introducing this controversial and initially popular model of addiction from past research of the late 1930`s and early 1940`s. His findings have received wide acceptance however, the research from which he

Psychology is a developing science which studies the mental functions, processes, and behaviors of an individual. In the science of psychology, many debates arise; nature vs. nurture is one of the most popular ones. These psychological debates are followed by research, backing up either nature or nurture or both. Nature suggest heredity impacts human psychological development; nurture suggests the environment impacts our psychological development. Addiction plays a large role in nature vs. nurture. Addiction is defined as a person being attached to a certain activity or item; an addict is one who has a dependency on particular substances or activity. There are many debates on whether addiction is caused by genes or the environment. Many researchers believe if they had the answer of addiction being a genetic condition or an environmental factor, they would be able to resolve the problem of addicts, or so they believe.

Among the numerous definitions for addiction, there lies yet another to define it from a biochemical perspective. Milkman (1983) defines it as “self-induced changes in neurotransmission that result in social problem behaviors." This definition encompasses the psychological, biochemical and social aspects of addictive processes. It is not limited to substance abuse and can be applied to any activity characterized by compulsion, loss of control and continuation of the substance despite harm. This has helped investigators gain a better understanding of the nature of addiction.

The disease model of addiction rests on three primary assumptions predisposition to use a drug, loss of control over use, and progression (Krivanek, 1988, p.202). These physiological alterations cause an undeniable desire to take more drugs (McNeece & DiNitto, 2012). Addicts are viewed as individuals with an incurable disease with drug addiction as the symptom. The disease model argues users cannot be held accountable for their addictions (Kirvanek, 1988).

The National Institute for Drug Abuse agrees by breaking down a more biological understanding of addiction. Their method is known as a "disease model." They believe that it is quite clear that drug addiction is "considered a brain disease because drugs change the brain-they change it's structure and how it works." The disease model consists of some well thought out points. It states that drug addiction is a brain disease because repeated use and abuse of drugs changes the brain. Drug addiction alters brain pleasure centers, so that normal happiness requires higher and more frequent drugs. Brain imaging studies show changes in the brain that are critical to judgement, decision making, and behavior control. The risk for becoming an addict is greatly dependent on one's biology, such as gender or ethnicity. The prepondrance of research indicates neurological effects of repeated drug

The biopsychosocial model doesn’t rely on one factor as some of the other theories do. It would appear to be a more suitable means of diagnosing why someone has become addicted, as it has a multifaceted approach which incorporates social, cultural, physical and psychological factors ( Donovan & Marlatt, 2005).

There are many models and theories which attempt to explain the causes of substance misuse and dependence. They range from those which highlight the importance of genetic and biological factors to those which stress social and psychological factors and those which may consider the ‘blame’ to be that of the dependent individual (Rassool 2009).

The social model of addiction tries to recognize and repair systematic problems within society that could impact a person’s choice about substance use (Doweiko, 2015). Cultural, environmental, and family components of a person’s life are all a part of the social model. These influences can either enable the development of addiction or increase resistance against addiction. For instance, in distinct cultures and environments, the manufacture, sale, and distribution of illicit drugs are considered as acceptable behaviors for a person to prosper and gain respect (Doweiko, 2015). Social aspects such as poverty, community immersion, unemployment, and family structure either influence or guard the person from substance abuse. Identification of adverse social influences so that these concerns can be attended to will decrease the probability of the individual relapsing or the continued abuse of substances (Doweiko, 2015).

Addiction is formed by an initial choice fueled by external beguiling factors. From the time we are born, we know absolutely nothing, our minds are a blank slate. In fact, according to Jean Piaget’s cognitive stages of development, the mind does not begin to think abstractly from concrete ideas or reason until the final stage (formal operational), which lasts all the from age twelve and on. Because of this, we can deduce that at any age in our development, we are susceptible to external factors influencing our behavior. With that being said, a person’s decision to participate in the use of any substance is influenced by much more than their knowledge that it is “wrong”. Peer pressure, stress, curiosity or even medical practices can ignite the choice to abuse substances. The majority of addictions that begin in the pre-teen and teenage years stem from their exposure to drugs and alcohol in the media, many even claim that

Substance addiction can hugely impact on a person’s thinking, functioning and behaviour. Whilst depressant drugs such as alcohol and opioids slow down your central nervous system (CNS), stimulants such as cocaine or amphetamine increase the activity of the CNS, leading to higher blood pressure, heart rate and increased alertness. Repeated abuse of the substance leads to tolerance and withdrawal, in turn this leads to the user showing signs of irrational behaviour. Another form of substance abuse is hallucinogens; they can cause powerful changes in sensory perceptions. It works by binding to the serotonin receptors, these neurons control visual information and emotions, and this can lead to various effects on the user. Neurobiology can help us understand the reasons for addiction and the effects they have on us. Groman and Jentsch (2012) discuss key issues of differentiating the causes and consequences of addiction through neuroimaging and behavioural research on monkeys, they found that the dysfunction of the dopamine

The three models of addiction examined in this week’s readings include the medical model, the psychosocial model, and the disease of the human spirit model. The medical model “rests on the assumption that disease states are the result of a biological dysfunction, possibly one on the cellular or even molecular level” (Doweiko, 2012, p. 333). Many consider this model and “maintain that much of human behavior is based on the interaction between the individual’s biological predisposition and the environment” (Doweiko, 2012, p. 333). Individuals under this model view free will “as an illusion” (Doweiko, 2012, p. 333). There is controversy regarding this model as “to the degree to which the

All types of addictions should be looked at from a philosophical and psychological point of view. Those in the fields of neuroscience, psychology and philosophy often compare their views to show the similarities of addictions whether they be substance induced or behavioral. “Behavioral science experts believe that all entities capable of stimulating a person can be addictive; and whenever a habit changes into an obligation, it can be considered as addiction” (Alaghemandan et al 290). Some addictions can affect people physically. Caffeine and nicotine provide prime examples. The body’s physical state becomes dependent on its effects and causes withdrawal symptoms without use. One of the main differences in behavioral and substance addictions is that behavioral addictions have no apparent physiological or physical withdrawal symptoms. It is not the physical body that is addicted, but the feeling that one gets mentally. The physical body is only affected by the

Studying and developing the biology of addiction allows us to understand the science behind the brain disease. Through years of research, science have found that a consistent usage of substance can actually alter the brain’s function. Substances interfere with major neurotransmitter systems such as dopamine, serotonin, GABA and glutamate. Unfortunately, this makes being “able to successfully maintain a year of sobriety.” extremely difficult which involves “three or four false starts.” (p.38) Michael Dennis of Chestnut Health Systems comments “That can often take eight or nine years.”(p.38) In fact, the change in the brain’s shape is affected by the overuse of substances. Their path to recovery may be thought to be difficult due to the government

The definition provided above is accessible and easy to understand; however, it initiates false beliefs among individuals because it fails to acknowledge that drug addiction is a mental health problem. Moreover, when words such as, “dependence”, “control” and “craving” are used to define drug addiction, it leaves an impression to the reader that addicts are indeed “people who cannot control their impulses.” Consequently, when we fail to recognize that drug addiction is a mental health problem, our focus is diverted towards the physical aspect of drug addiction. This could cause the belief among individuals that drugs alone cause the addiction. It is essential to acknowledge that there are chemical hooks in drugs; however, individuals need to understand that drugs alone do not cause the addiction. We need to identify and distinguish the “root cause” of addiction and ask ourselves: what caused the individual to take the drug in the first place?

Every day, hundreds of people experience the overwhelming effects of addictions. Individuals can become addicted to virtually any action or item. If individuals use addictive substances, there will be serious medical repercussions. This paper will focus on the idea of addiction through the fields of anthropology, psychology, and sociology, and how these fields have benefitted this prominent issue. Addictions are currently being researched by various social scientists in an attempt to fully understand their causes and cures.
