Scientists estimate that genes, including the effects environmental factors have on a person's gene expression, called epigenetics, account for between 40 and 60 percent of a person's risk of addiction. Also, teens and people with mental disorders are at greater risk of drug use and addiction than others..
What is the biological perspective of psychology on addiction?
The biological basis of addiction helps to explain why people need much more than good intentions or willpower to break their addictions. “A common misperception is that addiction is a choice or moral problem, and all you have to do is stop. But nothing could be further from the truth,” says Dr..

Who created the biopsychosocial model of addiction?
In the 1970s, the now famous psychologist George L. Engel came up with the biopsychosocial model of treatment. While many therapists were devoted to treating one particular aspect of a person’s mental struggles, he found it was best to treat people from all angles..

Biological Exposure Theory This theory suggests that regular ingestion of drugs will diminish the body's natural production of dopamine, a neurotransmitter that controls the brain's pleasure center. As a result, an individual may develop a substance addiction to make up for the lack of dopamine.

The biological model of addiction is a theory that explains the biological changes that occur within the brain as a result of substance use. It explains how these changes create a compulsion to continue using substances, regardless of the consequences. And how they make it hard for people to quit.
According to the biological model, each person's unique physiology and genetics causes addiction. People differ in the degree to which they like or dislike a particular addictive substance or activity. Some people may enjoy a substance or activity so much that it becomes very tempting and difficult to resist.

The biological model of addiction is used to explain why some people become addicted to certain substances, while others use the same substances but do not become addicted. This model demonstrates how addiction is seen as a disease that impacts each individual differently.
Is addiction psychological or biological?
Addiction is defined as a disease by most medical associations, including:
the American Medical Association and the American Society of Addiction Medicine. Like diabetes, cancer and heart disease, addiction is caused by a combination of behavioral, psychological, environmental and biological factors.
Is addiction really a biological disease?
Thinking of addiction as a disease might simply imply that medicine can help, but disease language also oversimplifies the story and leads to the view that medical science is the single best framework for understanding addiction. Addiction becomes an individual problem, reduced to the level of biology alone.
What are the biological theories of addiction?
Biological models of addiction emphasize the importance of genetics and the biological forces of nature. These theories suggest that brain chemistry, brain structure, and genetic abnormalities cause human behavior. Many of these models have not been tested or applied to every specific type of addiction.
What are the models and theories of addiction?
There are several theories that model addiction:
genetic theories
exposure theories (both biological and conditioning)
and adaptation theories. To be successful, an addiction model must blend the multidimensional aspects of addiction.
Biological psychology and addiction
Disorder resulting in compulsive behaviours
Addiction is a neuropsychological disorder characterized by a persistent and intense urge to use a drug or engage in a behaviour that produces natural reward, despite substantial harm and other negative consequences. Repetitive drug use often alters brain function in ways that perpetuate craving, and weakens self-control. This phenomenon – drugs reshaping brain function – has led to an understanding of addiction as a brain disorder with a complex variety of psychosocial as well as neurobiological factors that are implicated in addiction's development. Classic signs of addiction include compulsive engagement in rewarding stimuli, preoccupation with substances or behavior, and continued use despite negative consequences. Habits and patterns associated with addiction are typically characterized by immediate gratification, coupled with delayed deleterious effects.
The disease model of addiction describes an addiction as a disease with biological, neurological, genetic, and environmental sources of origin. The traditional medical model of disease requires only that an abnormal condition be present that causes discomfort, dysfunction, or distress to the affected individual. The contemporary medical model attributes addiction, in part, to changes in the brain's mesolimbic pathway. The medical model also takes into consideration that such disease may be the result of other biological, psychological or sociological entities despite an incomplete understanding of the mechanisms of these entities.
Internet addiction disorder (IAD) can otherwise be referred to
Excessive internet use that causes psychological disorders
Internet addiction disorder (IAD) can otherwise be referred to as problematic internet use or pathological internet use. It is generally defined as problematic, compulsive use of the internet, that results in significant impairment in an individual's function in various aspects of life over a prolonged period of time. Young people are at particular risk of developing internet addiction disorder, with case studies highlighting students whose academic performance plummets as they spend more and more time online. Some also experience health consequences from loss of sleep, as they stay up later and later to chat online, check for social network status updates or to further progress in a game.
Compulsive sexual behaviour driven by use of pornography
Pornography addiction is the scientifically controversial application of an addiction model to the use of pornography. Pornography may be part of compulsive sexual behavior with negative consequences to one's physical, mental, social, or financial well-being. While the World Health Organization's ICD-11 (2022) has recognized compulsive sexual behaviour disorder (CSBD) as an impulsive control disorder, CSBD is not an addiction, and the American Psychiatric Association's DSM-5 (2013) and the DSM-5-TR (2022) do not classify compulsive pornography consumption as a mental disorder or a behavioral addiction.
Proposed compulsive sexual disorder
According to proponents of the concept, sexual addiction, also known as sex addiction, is a state characterized by compulsive participation or engagement in sexual activity, particularly sexual intercourse, despite negative consequences. The concept is contentious; neither of the two major mainstream medical categorization systems recognise sex addiction as a real medical condition, instead categorizing such behavior under labels such as compulsive sexual behavior.
