Mental Health

Mental health includes our emotional, psychological, and social well-being. It affects how we think, feel, and act, which means, it’s crucial to get right.


Mental health is health, and it is one of the most important aspects of overall well-being. When one's mental health is affected, it can be difficult to deal with life stressors, set goals in life and meet them, and have an overall good quality of life. One of the most prevalent issues affecting mental health today is that of substance use disorder. Substance use disorder, also known as SUD, is one of the most common conditions affecting Americans in modern times.

As of 2022, substance abuse in America is on the rise, with 20.4 million people diagnosed with substance use disorder in the past year according to the National Institute on Drug Abuse. Of these people, only a little over 10 percent sought help, and around 43% of all people seeking help for addiction related to prescription pain killers had a co-occurring mental illness.

What do these numbers tell us? For starters, they point to the bigger picture of mental health related to substance use disorder. They also paint the picture for how prevalent drug use is in the United States. It's important to be educated on the link between drug addiction mental health, and know how to get help to recover from a mental illness as well as substance use disorder.

What is Substance Use Disorder?

It's important to understand the difference between substance use disorder and have addiction defined in our vocabularies. Substance use disorder, according to the DSM-5, or Diagnostic Statistical Manual 5th edition, is the recurrent use of drugs or alcohol despite the negative effect it has had on one's own life and health. There are now 11 criteria for a person to meet the definition of substances use disorder, which include:

  1. Drug dependence and tolerance, meaning a person needs a drug or substance to function, and needs more of it than usual to function
  2. Withdrawal symptoms are experience when someone tries to quit
  3. Intense cravings for a substance
  4. A person uses the drug in a hazardous manner not prescribed by a doctor or other medical professional or puts themselves in danger in order to consume the drug
  5. Someone experiencing social and personal problems related to the use of a drug and psychological addiction
  6. A person begins to neglect their roles in life, such as a parental role, at work or at school
  7. Someone begins to use larger amounts of a substance for a longer period of time
  8. Someone has tried to get help and quit numerous times but simply can't do it
  9. There is more time spent using the drug
  10. Someone has given up activities they used to love just to use
  11. Psychological problems have now arisen due to the drug abuse

A person only needs to meet two of these criteria in order to be labeled as having a substance use disorder.

Is substance abuse a mental health issue?

In short, it's important to understand that substance abuse disorder is considered a mental health disorder in its own right. From the criteria above, it's easy to see how all of these could pose a potential threat to someone's physical, emotional, and mental well-being. From abandoning activities they once loved, which can cause depression, to increasing anxiety when one is unable to fulfill their addiction, co-occurring mental health disorders go hand in hand with substance use disorder.

However, perhaps the most relevant (and dangerous) of these criteria is changes in psychological well-being, such as erratic behavior, an increase in depression and anxiety, and other factors related to mental health. When people are diagnosed with substance abuse disorder, it's important that they get help through addiction and mental health counseling.

In addition, people with substance use disorder are also considered to have a mental health disorder, as classified by the National Institute of Mental Health. This is because having a substance use disorder affects parts of the brain before, during, and after drug use. Some of the parts of the brain affected include:

  • The Basal Ganglia, which plays a role in pleasure and motivation to complete activities such as sex, eating, and completing goals. Drugs affect the pleasure center through repeated exposure, which leads to the inability to feel pleasure from anything else besides the drug. This makes it difficult to recover from substance abuse, even after someone gets addiction help.
  • The Extended Amygdala, a part of the brain where the feelings of anxiety, fear, and other types of feelings like agitation and irritability arise from. During the withdrawal process, this part of the brain is activated, and becomes more and more sensitive as time progresses. Agitation is one of the hallmarks of withdrawal symptoms, as is erratic behavior.
  • The Prefrontal Cortex, which allows a person to be rational and make decisions based on conscious choices. This is one of the final parts of the brain to mature, and in people with substance use disorder, it can be difficult to control the prefrontal cortex. It makes it difficult for someone to control their impulses before, during, and after using substances.

How are mental health and addiction related?

In addition to affecting the brain, substance use disorder can also exist alongside another mental health disorder. In fact, according to the National Institute on Drug Abuse, around 7.7 million people are diagnosed with both a substance use disorder and a co-occurring mental health disorder. Unfortunately, it can be difficult to diagnose which disorder came first, whether it was mental illness or the substance or alcohol use disorder.

For people with a co-occurring mental disorder, it's important to get help for both addiction and mental health counseling. Unfortunately, it can be difficult to know which disorder came first, whether it was mental health disorder or the substance use disorder. For people with mental health and addiction issues, not only is it difficult to understand which came first, but it can also be difficult to understand how to treat both of the disorders together.

For instance, if someone has a serious mental health illness with schizophrenia, it can be difficult for a substance abuse counselor to offer addiction help until after the person is stabilized. This is just one of many disorders that can coincide with addiction.

Some of the mental health disorders that can coincide with addiction include:

  • Schizophrenia
  • Bipolar disorder (all types)
  • Post-traumatic stress disorder or PTSD
  • Anxiety
  • Depression
  • Borderline Personality Disorder
  • Obsessive Compulsive Disorder, or OCD
  • ADHD, or attention-deficit hyperactivity disorder

For all of these disorders, research shows that offering both mental health and addiction counseling is beneficial in improving treatment outcomes. That's why it's so important to find the right counselor and get help for both your mental health disorder, as well as any addiction issues you or a loved one might face.

How is mental health related to a dual diagnosis?

There has been research studies done on people that have undergone both substance use disorder and dual-diagnosis treatment. Dual-diagnosis treatment, as the name suggests, is treatment that focuses on both a mental illness and an addiction disorder. For instance, someone with post-traumatic stress disorder might engage in substance use disorder so they can get help for both their addiction and also go through trauma recovery.

Although past methods of treatment focused on treating a mental illness before treating a substance use disorder, new evidence from these research studies places emphasis on a dual-diagnosis treatment program. These studies have shown various promising outcomes, including:

  • Increased abstinence from drugs and alcohol after treatment, which indicates better outcomes in terms of long-term sobriety
  • A reduction in the symptoms of a person's mental illness itself
  • Better employment outcomes after treatment
  • Better participation in outpatient treatment and adherence to other treatment after initial recovery

These studies show just how important it is to find a program that focuses on dual diagnosis treatment, meaning they can offer counseling for both mental health and addiction. In addition, these studies also showed that dual diagnosis treatment can be effective in people with less severe psychiatric disorders, and in fact is even more impactful for people with these types of less severe psychiatric conditions. This means that you can seek help for even mild forms of depression, anxiety, PTSD, or other mental health conditions while still getting help for your substance use disorder.

Effects of substance abuse on mental health

For people with more severe psychiatric conditions, such as schizophrenia and bipolar disorder, it's important to get help right away for addiction. Evidence suggests that using drugs and alcohol can have a negative impact on an existing mental health disorder. For instance, people with ADHD report higher levels of cravings with drugs and alcohol after use. Brain imaging tests have been used to determine that this isn't a lone phenomenon, and there are actually images that show brain activity for cravings is heightened in people with ADHD, or attention-deficit hyperactivity disorder.

In addition, in people with bipolar disorder, evidence also shows that using cocaine might actually lead to symptoms of bipolar disorder progressing and getting worse over time. Other evidence also shows that using cocaine can make symptoms of bipolar disorder worse.

Using drugs and alcohol can also lead to certain symptoms that are similar to a mental health disorder, but that might not necessarily be the disorder itself. For instance, people that use substances such as LSD, psychedelic mushrooms, or methamphetamine can experience delusions and psychosis, similar to what someone with schizophrenia would experience. However, there is no way to know for certain whether or not someone is undergoing psychosis due to a substance or due to a pre-existing mental health disorder.

In short, it's best to stay away from using substances if someone has a diagnosed mental health disorder or is undergoing a significant life stressor. Although the substance, such as drugs or alcohol, might be able to help someone relax in the present moment, the effects of the substance will eventually wear away, leaving nothing but destruction and an unfortunately negative effect on mental health in its wake.

Can drugs cause mental illness?

Although the incidents of mental illness and an existing substance use disorder are high, this doesn't necessarily mean that drugs lead to mental illness. For researchers and doctors, it can be difficult to understand whether drug use leads to a mental disorder, such as psychosis, increased anxiety and depression, or if a mental illness leads to substance use.

For example, if someone was already suffering from depression and used alcohol as a way to self-medicate, then it can be difficult to know for certain whether the depression is the cause of the alcohol use disorder and vice versa. In addition, there are many other factors that can affect someone's risk of developing a mental illness. These include:

  • Past trauma, especially childhood trauma which has a negative effect on someone's developing brain.
  • Genetic factors, since having a family member with a pre-existing mental illness also increases the risk of someone developing that same mental illness. In people with OCD, for instance, the risk of developing the condition is greater if someone has an immediate relative with the condition.
  • Environmental factors, such as the friends and family one keeps around them and their relationship to drugs and alcohol.
  • Head trauma or even pre-existing medical conditions.
  • Life stressors such as the loss of a loved one, job, or poor finances.

While all of these factors listed above can lead to mental illness, it's important to notice that using substances alone might not cause mental illness. While the symptoms of depression, psychosis, and anxiety can get worse or even develop during the use of substances, one can never know for certain whether they need help for the addiction or the mental illness itself.

This is also why it's incredibly important to keep dual diagnosis as a viable option for treatment. It's always a better treatment method to treat both the mental disorder and the substance abuse disorder than to ignore one or the other.
