Substance Abuse and Mental Health Issues
What is the link between substance abuse and mental health?
- Roughly 50 percent of individuals with severe mental disorders are affected by substance abuse.
- 37 percent of alcohol abusers and 53 percent of drug abusers also have at least one serious mental illness.
- Of all people diagnosed as mentally ill, 29 percent abuse either alcohol or drugs.
While substance abuse problems and mental health issues don’t get better when they’re ignored—in fact, they are likely to get much worse—it’s important to know that you don’t have to feel this way. There are things you can do to conquer your demons, repair your relationships, and start enjoying life again.
What comes first: Substance abuse or the mental health problem?
Substance abuse and mental health disorders such as depression and anxiety are closely linked, and while some substance abuse can cause prolonged psychotic reactions, one does not directly cause the other. However:
Alcohol and drugs are often used to self-medicate the symptoms of mental health problems. People often abuse alcohol or drugs to ease the symptoms of an undiagnosed mental disorder, to cope with difficult emotions, or to temporarily change their mood. Unfortunately, abusing substances causes side effects and in the long run often worsens the symptoms they initially helped to relieve.
Alcohol and drug abuse can increase the underlying risk for mental disorders. Mental disorders are caused by a complex interplay of genetics, the environment, and other outside factors. If you are at risk for a mental disorder, abusing alcohol or illegal or prescription drugs may push you over the edge. There is some evidence, for example, that certain abusers of marijuana have an increased risk of psychosis while those who abuse opioid painkillers are at greater risk for depression.
Alcohol and drug abuse can make symptoms of a mental health problem worse. Substance abuse may sharply increase symptoms of mental illness or even trigger new symptoms. Abuse of alcohol or drugs can also interact with medications such as antidepressants, anti-anxiety pills, and mood stabilizers, making them less effective at managing symptoms.
Do I have a substance abuse and co-occurring mental health problem?
It can be difficult to diagnose a substance abuse problem and a co-occurring mental health disorder. It takes time to tease out what might be a mental disorder and what might be a drug or alcohol problem. The signs and symptoms also vary depending upon both the mental health problem and the type of drug being abused. For example, the signs of depression and marijuana abuse could look very different from the signs of schizophrenia and alcohol abuse. However, there are some general warning signs that you may have a co-occurring disorder:
- Do you use alcohol or drugs to cope with unpleasant memories or feelings, to control pain or the intensity of your moods, to face situations that frighten you, or to stay focused on tasks?
- Have you noticed a relationship between your substance use and your mental health? For example, do you get depressed when you drink?
- Has someone in your family grappled with either a mental disorder or alcohol or drug abuse?
- Do you feel depressed or anxious even when you’re sober?
- Do you have unresolved trauma or a history of abuse?
- Have you previously been treated for either your addiction or your mental health problem? Did the substance abuse treatment fail because of complications from your mental health issue or vice versa?
