Is Addiction Hereditary Or Considered A Genetic Disorder?
As a counselor, I have had the privilege of working with many individuals who struggle with a substance use problem such as drug abuse and alcoholism. Addiction is a complex and multifaceted issue that can have a profound impact on a person’s life.
Addiction is considered to have a genetic component, but it is not solely a genetic disorder. Research has shown that genetic makeup can play a role in the development of addiction, including both substance use disorders and behavioral addictions. However, environmental factors, such as social and psychological stressors, peer pressure, and access to addictive substances or behaviors, can also contribute to the development of addiction.
Drug addiction and alcohol addiction are two of the most common forms of addiction. Both drug and alcohol addiction can have devastating effects on a person’s health, relationships, and overall quality of life.
While the specific causes of drug and alcohol addiction may vary, both conditions are believed to be influenced by genetic, environmental, and social factors.
Effective treatment for drug and alcohol addiction typically involves a combination of interventions, including behavioral therapy, medication, and support groups.
With the right treatment and support, individuals struggling with drug addiction and alcohol addiction can overcome these conditions and lead fulfilling, healthy lives.
In this article, we will explore the genetic basis of addiction, the difference between a disorder and an addiction, and the specific gene related to addiction.
What Type of Disorder is Addiction?
Substance use disorders are a type of mental health disorder that involves the use of drugs or alcohol in a way that causes negative consequences. Addiction is a chronic disease that affects the brain’s reward system, leading to compulsive drug seeking and use, despite the negative consequences.
Addiction is a complex issue that involves both genetic and environmental factors.
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), is the diagnostic criteria used by healthcare providers to diagnose substance use disorders.
The DSM-5 outlines 11 criteria for diagnosing a substance use disorder, including:
- Using the substance in larger amounts or for longer periods than intended
- Wanting to cut down or stop using the substance but being unable to do so
- Spending a significant amount of time obtaining or using the substance, or recovering from its effects
- Craving the substance
- Continuing to use the substance despite the negative consequences it causes
- Giving up important activities or responsibilities because of substance use
- Using the substance in situations where it is physically hazardous
- Developing tolerance to the substance
- Experiencing withdrawal symptoms when not using the substance
- Using the substance to avoid or alleviate withdrawal symptoms
- Continuing to use the substance despite knowing that it is causing or worsening a physical or mental health condition
To be diagnosed with a substance use disorder, a person must meet at least two of these criteria within a 12-month period.
The severity of the disorder is determined by the number of criteria that are met, with mild disorders involving 2-3 criteria, moderate disorders involving 4-5 criteria, and severe disorders involving 6 or more criteria.
What Is The Genetic Basis Of Alcoholism?
Research has shown that genetic factors play an important role in the development of addiction. Studies of family members and identical twins have shown that genetic predisposition to addiction can be passed down through generations.
Specific genes related to addiction have been identified, including the OPRM1 gene, which is involved in the brain’s reward system and the metabolism of drugs.
Research has identified several candidate genes that may play a role in the development of alcoholism. For example, genes that affect the metabolism of alcohol, such as ADH and ALDH, have been linked to a higher risk of developing AUD.
Other genes that affect the brain’s reward system, such as DRD2 and OPRM1, have also been implicated in alcoholism.
In addition to specific genes, genetic predisposition to alcoholism can be influenced by a variety of factors, including family history of alcoholism, hereditary factors, and epigenetic changes.
Family studies have shown that a person’s risk are higher if they have a family history of alcoholism, even when they are raised apart from their biological families.
Identical twin studies have also shown that identical twins are more likely to both have AUD than fraternal twins, suggesting a genetic component to the disorder.
Epigenetic changes, which are changes in gene expression that are not caused by changes in the underlying DNA sequence, can also play a role in the development of alcoholism.
Environmental factors such as stress, diet, and exposure to toxins can trigger epigenetic changes that affect gene expression, potentially increasing the risk of developing AUD.
What Is The Difference Between A Disorder And An Addiction?
While substance use disorders and addiction are often used interchangeably, they are not the same thing. A substance use disorder involves the use of drugs or alcohol in a way that causes negative consequences, but it does not necessarily involve compulsive drug seeking and use.
Addiction, on the other hand, is a specific type of substance use disorder that is characterized by compulsive addictive behaviors such as drug-seeking and continued use of a substance despite negative consequences.
Addiction is often associated with physical dependence, tolerance, and withdrawal symptoms. People with addiction may experience intense cravings for the substance and may have difficulty controlling their use.
While addiction is a type of substance use disorder, not all substance use disorders meet the criteria for addiction. For example, a person with a mild substance use disorder may experience some negative consequences as a result of their substance use but may not meet the criteria for addiction.
Similarly, a person who has been diagnosed with a substance-induced disorder, such as alcohol-induced anxiety disorder, may not meet the criteria for addiction even though their substance use is causing significant impairment.
It is also worth noting that while addiction is often associated with illegal drugs, it is possible to develop addiction to prescription drugs or alcohol. In fact, alcohol use disorder is one of the most common substance use disorders, affecting millions of people worldwide.
What Gene Is Related To Addiction?
There is no one specific gene related to addiction, as it is a complex issue that involves multiple genetic variations.

Research has identified a number of genes that may contribute to the development of addiction. For example, variations in the DRD2 gene, which is involved in dopamine signaling in the brain, have been associated with an increased risk of addiction.
Similarly, variations in the OPRM1 gene, which codes for the mu-opioid receptor, have been linked to opioid addiction.
Other genes that have been associated with addiction include those involved in stress response, such as the CRHR1 gene, and those involved in reward processing, such as the COMT gene.
However, it is important to note that the relationship between genes and addiction is complex, and the influence ofany single gene is likely to be small.
In addition to specific genes, researchers have also identified genetic variations that may increase a person’s overall risk of developing addiction. For example, studies have suggested that individuals with a family history of addiction may have a higher genetic risk for the condition.
Additionally, some studies have suggested that certain genetic variations may increase the risk of addiction in response to specific environmental factors, such as stressful situations or trauma.
While genetic and environmental risk factors can increase the likelihood of developing addiction, there are also protective factors that can help mitigate this risk. Protective factors are traits or conditions that can help individuals avoid or overcome addiction, even when faced with risk factors.
Examples of protective factors include strong social support networks, positive coping strategies, a stable and nurturing home environment, and access to mental health and addiction treatment services.
Building and reinforcing these protective factors can help individuals develop resilience to addiction, and may help prevent the onset of addiction in the first place.
For individuals who have already developed an addiction, protective factors can help support recovery efforts and reduce the risk of relapse. Understanding the role of protective factors in addiction can be an important part of developing effective prevention and treatment strategies.
In conclusion, addiction is a complex issue that involves both genetic and environmental factors. While there is no one specific gene related to addiction, research has shown that genetic factors play an important role in the development of addiction.
Understanding the genetic basis of addiction can help healthcare providers develop effective treatment options for individuals struggling with substance use disorders.
If you or someone you know is struggling with addiction, seek help from a healthcare provider or addiction treatment center. Recovery is possible with the right support and resources.
