As societal views of addiction continue to evolve, so does our understanding of this complex and often debilitating disease. While traditionally viewed as a lack of willpower or moral failing, addiction is now recognized by the medical community as a chronic condition that affects millions of people worldwide.

In recent years, there has been much debate over whether addiction should be classified as a mental illness. Some experts argue that addiction meets the criteria for several mental health disorders, including substance use disorder and compulsive behavior disorder. Others believe that addiction is its own unique condition that requires specialized treatment options.

“The brain changes associated with addiction are similar to those seen in other psychiatric disorders such as depression, anxiety, and attention deficit hyperactivity disorder,” says Dr. Nora Volkow, director of the National Institute on Drug Abuse.

Despite differing opinions, one thing remains clear: addiction can have serious consequences for both physical and mental health. Individuals struggling with addiction may experience a wide range of symptoms, including mood swings, anxiety, insomnia, and even psychosis in severe cases.

If you or someone you love is dealing with addiction, it’s important to seek professional help and support. With the right care and resources, it’s possible to overcome addiction and achieve long-term recovery.

The Definition of Addiction and Mental Illness

Addiction Defined

According to the American Psychiatric Association, addiction is defined as “a complex condition, a brain disease that is manifested by compulsive substance use despite harmful consequence.” In simpler terms, addiction refers to the state where an individual engages in activities or uses substances despite the negative consequences it may have on their lives.

Some common forms of addiction include alcoholism, drug abuse, internet addiction, gambling, and shopping. These addictions can lead to severe social, economic, psychological, and physical problems for those affected by them.

“Addiction isn’t about substance – you aren’t addicted to the substance, you are addicted to the alteration of mood that the substance brings.”
-Markham Heid

Mental Illness Defined

Mental illness, on the other hand, refers to a broad spectrum of disorders that affect one’s emotional, cognitive, behavioral, and mental health. Such conditions can trigger changes in mood, thinking patterns, behavior, and perception. Mental illnesses range in severity, from mild, temporary distress to severe disability requiring hospitalization.

Some examples of mental illness include anxiety disorders, depression, schizophrenia, bipolar disorder, personality disorders, and eating disorders. These illnesses can lead individuals to experience significant impairments in many aspects of life, including social functioning, education, work, relationships, and self-care.

“Mental illness is nothing to be ashamed of but stigma and bias shame us all.”
-Bill Clinton

Is Addiction a Mental Illness?

The relationship between addiction and mental illness is often debated within the medical community. While some believe that addiction must be classified as psychiatric diagnoses, whereas others argue that it should not. Research has shown that addiction and mental illness often co-occur, with individuals affected by one likely to have comorbid diagnoses of the other.

Despite this link, substance use disorder – a term used to describe addiction – is still its own unique diagnosis, separate from many common forms of mental health conditions. However, it is also widely acknowledged that addiction can trigger or worsen pre-existing mental illnesses, such as depression or anxiety disorders.

“Addiction is not a choice anybody makes. It’s nature, not nurture; except when it isn’t.”
-Amy Reed

The debate regarding whether addiction should be classified as a form of mental illness is an ongoing one. Despite this, there are avenues for those struggling with addiction to find support and help through therapy, counseling, and medical intervention.

While there may not be a definitive answer on whether addiction classifies as a mental illness, it is clear that both hold significance in terms of their impact on individuals, families, and society at large. Therefore, it remains essential to prioritize prevention strategies, research, and funding towards tackling both issues.

Similarities Between Addiction and Mental Illness

Addiction and mental illness are two separate conditions, but there are some striking similarities between the two. The co-occurrence of addiction and mental illness is very high because both problems tend to go together, and they amplify each other’s effects.


According to statistics from the National Institute on Drug Abuse (NIDA), about half of the people who suffer from a substance use disorder also have a co-occurring mental health condition. Similarly, approximately 20% of people with a diagnosed mental illness struggle with drug or alcohol addiction. This means that people with either condition are more likely than not to develop the other as well.

“People with addictive disorders often experience comorbid psychiatric disorders,” says Dr. Michael Weaver, a professor at the University of Texas School of Medicine. “Many commonly abused substances can cause or exacerbate underlying mental health disorders such as depression, anxiety, bipolar disorder, and schizophrenia”.

The reasons for this correlation aren’t fully understood; however, it’s believed that early exposure to drugs, genetic tendencies, traumatic experiences, social isolation, lack of social support, and stress may all contribute to the development of both addiction and mental illness.

Similar Neurological Effects

In addition to their co-occurrence, there are some notable neurological similarities between addiction and mental illness. Brain imaging studies have found that both conditions affect similar areas in the brain and alter neurotransmitter release, which affects mood regulation and reward behavior.

“All addictions change brain function,” reports Stephanie Sarkis, Ph.D., N.C.C. and author of “Gaslighting: Recognize Manipulative and Emotionally Abusive People – and Break Free”. “The desirable ‘high’ someone gets from gambling, sex, and drugs floods the brain with dopamine. Over time, the brain develops tolerance to those levels of dopamine and needs more and more stimulation to get that same high.”

Mental illnesses like depression, anxiety, bipolar disorder, and schizophrenia affect some of the same neurotransmitter systems in the brain as addiction. This partly explains why addictive behaviors often emerge from or coexist alongside emotional disorders.

Moreover, both conditions rewire the brain’s reward center making it difficult for the person to feel a sense of pleasure without engaging in the activity, whether it’s drug use or certain thought patterns associated with mental illness. Over time, this rewiring can cause long-term negative effects on behavior, motivation, and physical health, which could take years of abstinence or therapy to reverse.

There are significant similarities between addiction and mental illness, particularly in their behavioral, neurological, and social consequences. Understanding these parallels can help clinicians develop better treatment strategies that address comorbid conditions effectively and enhance the likelihood of sustained recovery.

The Science Behind Addiction and Mental Illness

There is an ongoing debate in the medical community around addiction being a mental illness. Let’s dive into the science behind addiction and mental illness to better understand this topic.

Brain Chemistry

One reason why addiction is considered a mental illness is because of changes in brain chemistry that occur with substance abuse. Drugs, alcohol, and other addictive substances increase dopamine levels in the brain, which produces feelings of pleasure and reward. Over time, the brain’s reward system becomes desensitized to these substances, making it harder for individuals to feel pleasure from everyday activities. This leads to cravings and a compulsion to use the substance, which are hallmark symptoms of addiction.

In addition, research has shown that individuals with certain mental illnesses such as depression or anxiety have imbalances in their brain chemistry, particularly with serotonin and norepinephrine. Substance abuse can worsen these imbalances and exacerbate underlying mental health issues, leading to what is commonly referred to as a dual diagnosis.

“The relationship between addiction and mental illness often goes both ways—individuals living with a mental health disorder may turn to drugs and alcohol as a form of self-medication, while substance abuse can trigger or worsen mental health conditions.” -National Alliance on Mental Illness


Studies have also shown a genetic component to addiction, suggesting that certain individuals may be more susceptible to developing an addiction due to inherited factors. Scientists have identified genes that affect how the body processes drugs, including opioid receptors and enzymes that break down alcohol. Additionally, genetics play a role in vulnerability to mental illnesses such as depression and bipolar disorder, which can increase the risk of developing addiction.

While genetics cannot entirely predict whether someone will develop an addiction or mental illness, it can increase their likelihood of doing so. Furthermore, environmental factors such as trauma and stress can also trigger genetic predispositions to addiction.

“Genetics loads the gun. Environment pulls the trigger.” -Dr. Stephen Dilts

Environmental Factors

Mental health experts also recognize the role that social and environmental factors play in the development of addiction. Trauma, abuse, neglect, and other adverse childhood experiences (ACEs) have been shown to increase rates of addiction in adulthood. Moreover, poverty, lack of access to healthcare, discrimination, and other societal issues can further contribute to a person’s risk of developing addiction and hinder their ability to seek help.

Furthermore, some argue that addiction is not solely a personal failing but rather a symptom of larger structural problems in society, including systemic racism, economic inequality, and inadequate healthcare resources for addressing addiction and mental health disorders.

“Addiction shouldn’t be called ‘addiction.’ It should be called ‘ritualized compulsive comfort-seeking.’” -Dr. Gabor Maté

While there is ongoing debate around whether addiction qualifies as a mental illness, the science behind addiction supports many similarities between addiction and mental illness. Changes in brain chemistry, genetics, and environmental factors all contribute to the development of addiction and highlight the need for comprehensive approaches to treatment that address underlying mental health conditions. As a society, we must continue working towards reducing stigma surrounding mental illness and substance abuse in order to promote recovery and healing for those affected.

The Debate Among Experts

There is a hot debate among experts in the field of mental health about whether addiction can be classified as a disease. Some believe that addiction is purely a personal choice and that individuals have complete control over their use of drugs or alcohol. Others argue that addiction alters the brain’s chemistry and structure, leading to compulsive behavior that cannot easily be controlled.

Addiction expert Dr. Nora D. Volkow, director of the National Institute on Drug Abuse, has stated that addiction to drugs and alcohol “is a chronic illness characterized by drug seeking and use that is compulsive, or difficult to control, despite harmful consequences.” She believes that genetic predispositions combined with environmental factors contribute to addiction and that it should be treated as an all-encompassing disease rather than simply poor choices made by the individual.

On the other hand, Stanton Peele, a psychologist and author of numerous books on addiction, claims that addiction is not a disease but rather a lack of self-regulation that stems from underlying emotional issues. He argues that labeling addiction as a disease removes personal responsibility and autonomy, which does more harm than good for those struggling with substance abuse problems.

“Many people who may meet diagnostic criteria for a given disorder actually get better without treatment,” –Stanton Peele

Is Addiction a Disease?

Despite differing opinions about the classification of addiction, scientific research shows that drug and alcohol dependence causes physical changes in the brain, altering its chemistry and function. These changes make it increasingly difficult for the user to stop using once they become addicted. While some argue that users still have control over their actions, others point out that the brain’s pleasure and reward center becomes so overwhelmed that the desire to use overrides logical decision making.

The American Society of Addiction Medicine officially classifies addiction as a chronic disease that affects the reward, motivation, and memory circuitry in the brain. They state that “changes to these circuits cause characteristic biological, psychological, social, and spiritual manifestations” of addiction.

Many medical organizations, including the World Health Organization and American Medical Association, also classify addiction as a disease due to the changes seen in the brain and body when a user becomes addicted. Treatment plans often include medication to help restore chemical imbalances in the brain

Stigma and Discrimination

Whether or not addiction is classified as a disease can greatly affect how those who struggle with substance abuse are perceived by others. Those who view addiction as purely a choice often blame users for their behavior and believe that punishment rather than treatment is the best way to deal with drug abuse issues. This mindset creates stigma and discrimination that make it even more difficult for someone struggling with addiction to seek help.

On the other hand, those who view addiction as a disease understand that individuals need support and access to appropriate treatment options to break free from the cycle of addiction. Removing shame from the issue of addiction has been shown to increase willingness among addicts to ask for help without fear of judgment or isolation from society.

Treatment Approaches

If addiction is considered a disease, then it must be treated like any other illness. Many different approaches exist for treating addiction, but most focus on getting individuals to recognize the underlying emotional causes of substance abuse and teaching them healthier coping mechanisms to avoid relapse.

Cognitive Behavioral Therapy (CBT) is one such approach that teaches people how to identify problematic thoughts and emotions related to drug use and replace them with new, healthy ways of thinking and behaviors. Other forms of therapy focus on trauma recovery or involve family members in counseling sessions to provide additional support to the recovering addict.

Medication-assisted treatment (MAT) may also be used in conjunction with therapy to help reduce withdrawal symptoms and minimize drug cravings. While MAT is not always necessary, it can be a crucial component for those struggling with opioid addiction, as these withdrawal symptoms can be especially intense, making relapse more likely without proper medical intervention.

Role of Personal Responsibility

Regardless of whether addiction is classified as a disease or not, personal responsibility plays an important role in recovery. Those who take ownership for their actions are more likely to succeed in maintaining sobriety than those who remain in denial about the severity of their substance abuse issues. However, this does not mean that those suffering from addiction should be shamed or blamed for something they cannot fully control.

People struggling with addiction require access to effective treatment options that meet their individual needs. It’s important not to underestimate addiction’s effects on the brain and body. Furthermore, people in recovery often find strong social support networks helpful in maintaining sobriety and managing their emotional health long-term.

“Although addiction seems insurmountable, many individuals do recover,” –Kristina Jackson and Stephanie Peabody, National Bureau of Economic Research

The ongoing debate among experts concerning whether addiction is a mental illness will most likely persist until the end of time. Acknowledging a consensus view of addiction as characterized by both genetic and environmental factors which challenges self-control might significantly advance research, prevention, and treatment efforts aimed at reducing its societal impact.

The Importance of Understanding Addiction as a Mental Illness

For many years, addiction was viewed as a moral failing or a lack of willpower. However, this perception has shifted in recent decades with more scientific research and advancements in neuroscience. Today, addiction is recognized widely as a chronic disease that affects the brain’s chemistry and functioning.

Understanding addiction as a mental illness is crucial because it changes how we approach treatment, reduce stigma, and prevent relapse.

Improved Treatment Options

When addiction is treated as a moral failure, punishment tends to be the go-to strategy, such as incarceration or exclusion from society. When it comes to acknowledging addiction as a mental illness, however, there is a shift towards evidence-based medical options to address substance use disorders.

Research shows that addiction treatment works, but only when tailored to individuals’ needs based on underlying issues like depression, anxiety, or trauma. Addressing these co-occurring disorders can help people recover faster, stay clean longer, and maintain sobriety endurance.

“People need to understand that addiction is a brain disease. It can be successfully treated through medication and therapy, allowing those who suffer from addiction and their families to build healthy experiences.” -Michael Botticelli

Reducing Stigma

A substantial percentage of people believe addiction is an issue of personal choice or weak moral character. This belief creates barriers to care and adds immeasurable stigma to the people living with addiction. Such attitudes may lead people not to seek help, delay seeking help until the problem has gone far beyond control or become isolated from community support. Research repeatedly indicates that shame undermines mental health recovery.

On the other hand, understanding addiction as a treatable illness might decrease stereotyping, bigotry, and resentment directed at people with drug or alcohol use disorders.

“People don’t choose to develop an addiction; it’s not based on weak morals or a lack of willpower. Instead, substance abuse is affected by many factors, including genetics and development.” -David Sack

Preventing Relapse


Addiction recovery is never simple, even if individuals have achieved sobriety because there is always a risk of relapse. Therefore, understanding addiction as a mental illness can help reduce the chances of relapsing altogether.

To increase long-term success, doctors should monitor patients closely and provide early interventions to prevent relapse when symptoms return. Co-occurring psychological problems counseling and support groups are also necessary resources that can enhance appropriate coping strategies and positive psychosocial supports for those in remission.

“A relapse doesn’t mean you’re back to square one. It merely means that you need reinforcement to maintain your weight loss goals. Recognizing that relapse is normal and building that expectation into your treatment plan may be critical to producing better outcomes.” -Hunter Cressall
In conclusion, Addiction is recognized widely as a chronic disease that affects the brain’s chemistry and functioning. Understanding addiction as a treatable illness might decrease stereotyping, bigotry, and resentment directed at people with drug or alcohol use disorders, which could strengthen social networks leading to more significant recovery improvements. Addressing these co-occurring disorders can help people recover faster, stay clean longer, and maintain sobriety endpoints.

Frequently Asked Questions

What defines addiction as a mental illness?

Addiction is defined as a mental illness due to its impact on the brain’s reward system, leading to compulsive drug-seeking behavior and loss of control over substance use. It is classified in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as a Substance Use Disorder (SUD), which includes criteria for diagnosis such as tolerance, withdrawal, and social/occupational impairment.

Is there a genetic component to addiction that supports its classification as a mental illness?

Yes, there is a genetic component to addiction that supports its classification as a mental illness. Studies have shown that genes can influence an individual’s susceptibility to addiction, including those related to brain reward pathways, stress response, and impulsivity. Family and twin studies have also demonstrated a higher risk of addiction in individuals with a family history of substance use disorders, suggesting a hereditary component.

Can mental health disorders contribute to the development of addiction?

Yes, mental health disorders can contribute to the development of addiction. Individuals with mental health disorders such as depression, anxiety, or post-traumatic stress disorder (PTSD) may use drugs or alcohol to self-medicate and alleviate symptoms. This can lead to the development of addiction as they become reliant on substances to cope. It is important for individuals with co-occurring mental health and addiction disorders to receive integrated treatment to address both conditions simultaneously.

What is the relationship between addiction and brain chemistry?

Addiction is related to changes in brain chemistry, particularly in the brain’s reward pathway. Substance use activates the release of dopamine, a neurotransmitter associated with pleasure and reward, leading to feelings of euphoria. Over time, repeated drug use can alter the brain’s chemistry, leading to decreased dopamine release and a reduced ability to experience pleasure. This can contribute to the development of tolerance, withdrawal, and compulsive drug-seeking behavior associated with addiction.

How do treatment approaches differ for addiction as a mental illness compared to behavioral addiction?

Treatment approaches for addiction as a mental illness differ from those for behavioral addiction. Substance use disorders typically require detoxification followed by behavioral therapies, such as cognitive-behavioral therapy (CBT) and motivational interviewing (MI), and medications such as methadone or buprenorphine for opioid addiction. Behavioral addictions, such as gambling disorder or internet addiction, may be treated with CBT or other psychotherapies. Medications may also be used to address co-occurring mental health disorders that contribute to addiction.

What are the long-term effects of untreated addiction as a mental illness?

The long-term effects of untreated addiction as a mental illness can be severe and potentially life-threatening. Individuals with untreated addiction may experience physical health problems such as liver disease, heart disease, or infectious diseases. They may also experience social and occupational problems, including job loss, financial difficulties, and strained relationships. In severe cases, untreated addiction can lead to overdose and death. It is important for individuals with addiction to seek treatment as soon as possible to prevent these negative outcomes.
