What is a mental illness and substance use disorder?

ïMental illness and substance use disorderÍ describes when someone has a mental illness (like depression, anxiety or psychosis) and uses drugs or alcohol in a way that triggers or intensifies the mental illness.

What is the relationship between misusing substances and mental health?

The relationship varies from individual to individual, with a range of factors making some people more vulnerable to a mental illness and substance abuse disorder. These factors can be genetic, environmental, psychological or behavioural.

Experts agree there are four general types of relationships between mental illness and substance abuse. These are:

- a primary mental illness triggers or leads to substance misuse
- use of substances makes the mental illness worse or changes it
- dependence on drugs or alcohol leads to psychological symptoms
- misusing substances, or withdrawing from them, leads to psychiatric problems or illnesses.

Some people with mental illnesses use drugs or alcohol to ïself-medicateÍ. They find that using substances takes away troubling symptoms, at least in the short term. In the long-term, however, substance use worsens the symptoms, adds new symptoms and is likely to prolong the illness.

There is a lot of research underway now to see if drug use can spark mental illness in otherwise healthy people. Some people seem to have a pre-disposition to psychotic breakdown, which can be triggered by substance use. This is particularly the case with alcohol, cannabis and amphetamines.

Opinion is growing that persistent, heavy use of cannabis can cause psychosis even when the person does not have an underlying vulnerability - especially when people start using it at a young age while their nervous system is still developing.

It is even clearer from research that amphetamines can cause psychosis.

Both amphetamines and cannabis have a clear association with depression.

How common is mental illness and substance use disorder?

The number of people with co-existing mental illness and substance use disorders is growing. Some reasons for this are that more substances are available at a cheaper cost, so people – often younger people - are using more drugs. At the same time, many drugs are in stronger forms than before, so their effects are more intense and unpredictable.

More people are being diagnosed with mental illness and substance abuse disorders because of greater awareness of the disorder. Between 30 and 80 per cent of people with a mental illness have a coexisting substance abuse disorder. Seventy per cent of young people admitted to hospital with psychosis in NSW each year have a substance abuse disorder.

What kind of difficulties can result from a mental illness and substance use disorder?

Because so many factors are involved in a mental illness and substance use disorder, each

person with this sort of disorder experiences different things. He or she may have long periods of stability between mental health problems or misusing substances. Or they he or she may tend to use drugs only during an acute episode, such as in mania.

Dual Recovery Online http://draonline.org/  describes a general, shared pattern among people with mental illness and substance abuse disorders. The pattern looks like this:

- Symptoms Begin
- Symptoms Interfere
- Problems and Consequences Occur
- Self Defeating Behaviors Begin
- Self Esteem is Affected
- Crisis

*Continue
* Change and recover

ïSymptomsÍ in this case may be either psychological or drug-related, or both. (Click on any of these words for further information on mental disorders and conditions: clinical depression, anxiety disorders, schizophrenia, eating disorders, and bipolar disorders.)

People with mental illness and substance use disorders are more likely to:

  • have signs of their illness earlier in their lives
  • have more severe symptoms
  • have more disruption in their lives
  • have more frequent and longer periods of hospitalization
  • need more psychiatric medication than they would otherwise need if they werenÍt taking drugs.

Problems associated with mental illness and substance use disorders are not just physical and psychological. There are many potential social, emotional and financial problems such as:

  • Family problems or problems in intimate relationships.
  • Employment or school problems.
  • High risk behavior while driving.
  • Multiple admission for chemical dependency services due to relapse.
  • Multiple admissions for psychiatric care.
  • Increased emergency room admissions.
  • Increased need for health care services.
  • Legal problems and possible prison terms.
  • Homelessness.

Because so many factors are involved, expert help is needed from three directions - mental health workers, as well as drug specialists and social workers. This is to deal with the mental health, substance use and social situation of the person.

How do I know if I or a family member/friend has a mental illness and substance abuse disorder?

If any of the above descriptions sounds like you or someone you know, then it is a good idea to seek assessment from a professional. The earlier you seek help, the better.

People with a mental illness and substance use disorder might recognise one part of the disorder but not the other. For tips on talking to someone you think might have difficulties, click here. (How do I talk to someone who I think has a mental illness and substance use disorder?)

What kind of treatments are available?

In the past, mental illness services have tended to be quite separate from drug and alcohol services. This often made it hard for people with mental illness and drug/alcohol problems to find appropriate care.

Services are now working more closely to deal with a personÍs mental illness and substance use problems at the same time. The person may access help from both services in various forms. If they are currently being treated for a mental illness, this should include information and support to deal with the drug or alcohol problem. If they are currently part of a drug education or ïdetoxÍ program, staff can also link them to treatment for the mental illness

The person may recognise one part of the illness but not the other. Services try to work with the personÍs own view, at the same time providing information and education improve their understanding of the dual nature of the disorder.

It is important to get help as soon as possible with mental illness and substance use problems. Drug and alcohol services generally only provide treatment that the person is ready to accept. Treatment should include education and self management strategies. These will help the person deal with his or her increased vulnerability due to the interaction of the mental illness and the substance use.

If the person is at risk to him- or herself or others, mental health services have more power to intervene and provide treatment in illness.

Where can I find treatments and support in the ACT?

The best starting point for referral and help is to call the Mental Health CATT (Crisis Assessment and Treatment Team), phone 1 800 629 354 free call. CATT can then put you in touch with appropriate services.  You may also call the ACT Alcohol & Drug Program if you wish to start work on your substance use problem by calling (02) 6207 9977. If they canÍt help you directly, they can refer you to another service.

Dual Diagnosis Anonymous meets on Monday evenings 8-10, at the Junction Health Service, Corner of Moore and Rudd Street, Civic. All people are welcome, regardless of age, sex, sexual identity and/or preference; religion/lack of religious belief, current or past drug or alcohol usage, psychiatric diagnosis or emotional state.

How do I talk to someone who I think has a mental illness and substance use disorder?

ItÍs important to remember that you should talk to them the same way you talk to anyone else. Even if you are nervous, try to remain calm and talk in a normal voice.

If you are trying to encourage the person to get help, the first thing is to get their understanding about what is going on. You can ask them what help they would like, or offer to contact someone for them to talk to. If the person wants help, he or she may want to speak to family, a friend or GP in the first instance, rather than specialist services.

You might want to check in with the person that what you think is happening is the case. A simple question could be: ñHave you taken anything that might have affected you?î.  Try not to get in to an argument about what may or may not have happened. Keep focused on the things youÍve noticed about the person that concern you, and ask if they are also concerned. Remind them there are avenues to help if they want to take them, and that you can contact someone if they want.

People with mental illness arenÍt necessarily violent – in fact, very few are. But if someone is intoxicated, they are often less inhibited (meaning they canÍt control their feelings as much) and they are more likely to act on a violent impulse.

If you think the person might harm themselves, notify a family member or call the Crisis Team on 1800 629 354, even if the person doesnÍt agree. The Crisis Team will discuss the situation with you and make a decision about whether to attend. 

If someone is in need of medical assistance and has taken an illegal substance, never delay calling for help, for any reason. If it is an emergency, call 000. If you or a friend are aged between 12yrs and 18yrs and have taken pills or hurt yourself, CAHMS Crisis Line for Young People (02) 6205 1971.
