Is it about alcohol and/or other drug use or about mental health?

Many people who have mental health issues also have problems with alcohol and/or other drug use. The terms co-morbidity or dual diagnosis are often used to describe this.

Keep in mind that alcohol and/or other drugs can affect mental health, and mental health issues can impact on a person’s alcohol and/or other drug use. Prescription mental health medications can also interact with other alcohol and/or other drugs a person may be using.

Some common mental health issues include depression and anxiety. Illnesses such as schizophrenia and personality disorders are less common.

It can be hard to tell whether changes in a loved one’s behaviour or mood are due to mental health problems, alcohol and/or other drug use or both.
