Co-Occurring Disorders: Can Substance Abuse Cause Mental Illnesses?

May 14, 2021

Substance abuse and mental illness are often related. In some cases, drug abuse makes mental illness worse. On the other hand, a mental illness left untreated can lead to substance use disorder. In order to further understand the correlation between the two, it is essential first to define what they are.

What is substance abuse?

Substance abuse, which is often referred to as drug addiction, is an illness that causes a person to lose control of their actions and misuse legal or illegal drugs. Many factors contribute to a person’s tendency to abuse substances, ranging from curiosity to peer pressure. 

What is a mental illness?

Mental illnesses are diagnosable conditions that deal with changes in a person’s behavior and cognition. At the same time, they often adversely affect a person’s ability to function in social, family, or career activities. 

Mental illnesses can come in many forms. Some, like phobias, are considered mild and are not as intrusive to a person’s daily life as other kinds of mental disorders. 

 

Is drug abuse a mental illness?

Many medical professionals and organizations have conflicting assertions on whether drug abuse is a disease or not. However, the American Society of Addiction Medicine and the American Medical Association defines it as a disease. Additionally, the National Institute on Drug Abuse classified drug abuse as a mental illness due to the following reasons:

Drug abuse causes changes in the way a person’s body and brain functions

Drugs can affect how the brain and body react to stressful situations. Also, they can cause a person to lose their self-control or mess up their brain’s rewards system.

Drug abuse, if left untreated, can lead to other severe physical and mental health disorders.

The destructive effects of drug abuse can be chronic and could persist even after a person has quit abusing the drug.

Like other diseases, various factors cause drug abuse, including environmental factors, biological factors, and psychological factors. 

Even though genetics seems to be responsible for a significant part of the likelihood that a person will abuse drugs, many more factors affect this.

Drug abuse is also called a drug use disorder. This constant and frequent use of substances leads to clinically significant impairment in a person’s physical and social well-being.

Can substance abuse cause mental illnesses like bipolar disorder? 

Since substance use disorder is classified as a disease primarily because it is capable of physically transforming and rewiring a person’s brain as well as their behavior, it can lead to mental disorders. Even people who were mentally healthy before the said abuse develop mental illnesses as a result of the abuse.

 

What are co-occurring disorders?

Co-occurring disorders or dual diagnosis is the coexistence of both a substance abuse disorder and a mental health disorder. As mentioned earlier, drug abuse and mental health disorders are very closely related. People with mental health disorders are more likely to develop a drug use disorder, while people with substance abuse disorders have their mental health disorders get significantly worse. 

 

What are some common co-occurring disorders?

Most people with mental health issues do not get themselves diagnosed or checked by medical professionals. There are several reasons for this. Sometimes, people can be ashamed of their condition and fear judgment from others, while some people downplay it as something normal, even if it is not. Once these unchecked mental health disorders worsen, people are more likely to turn to substance abuse to cope with them.

The following are some examples of co-occurring disorders:

— Depression
— Bipolar disorder
— Anxiety
— Post-Traumatic Stress Disorder (PTSD)
— Eating Disorders
— Schizophrenia
— Obsessive-Compulsive Disorder (OCD)

Though not mental health disorders, some emotional problems can cause substance abuse disorder, such as having low self-esteem or anger management issues.

On the other hand, people being treated for mental health disorders are often prone to abusing the following substances:

— Alcohol
— Stimulants
— Opioids
— Tobacco
— Hallucinogens
— Prescription drugs

 

Which treatment should go first? Substance abuse disorders or mental health disorders?

It is usually tricky to diagnose co-occurring disorders since both abuse disorders tend to have similar symptoms. Because of this, it is important that diagnoses be made at the same time and treatment for the co-occurring disorders be done at the same time as well. 

This approach is called integrated intervention, where a person struggling with multiple disorders simultaneously is diagnosed and given treatment for both conditions simultaneously. This is crucial because people suffering from these conditions experience more severe symptoms and have a more challenging time coping with their illness.  

 

Statistics behind Co-Occurring Disorders

Unfortunately, co-occurring disorders are pretty prevalent in the United States, and the number appears to be growing. According to the Substance Abuse and Mental Health Services Administration (SAMHSA), about 7.9 million adults suffered from co-occurring disorders in 2014. But in their 2018 National Survey on Drug Use and Health, this number increased to about 9.2 million adults suffering from co-occurring disorders

 

Taking the proper steps towards healing from co-occurring disorders

Co-occurring disorders are capable of ruining a person’s life and future. Thus, they can be overbearing, and for some, seeing yourself or your friends or family struggle with it could feel hopeless.
