Awareness: Mental Health Facts
Hone your Awareness
- 15% of the world’s population (1.1 billion people) had a mental illness in 2016.
- 20% of Australians are experiencing a current and chronic mental health or behavioural condition.
- Current treatment options are inadequate: typical treatments work for only about half of people with mental illness, and even when they do, most continue to experience some symptoms, and most relapse within the first year or two after treatment stops.
- In Australia, mental illness is the leading cause of non-fatal disease burden, and the third leading cause of total disease burden.
- The direct cost of mental illness in Australia is at least $28.6 billion annually.
- Well-designed clinical trials with psychedelic-assisted psychotherapy have produced impressive results, demonstrating their potential to be a game-changer for mental health treatment.

Global mental illness - prevalence and burden

Australia mental illness - prevalence and burden
In 2017-18, one in five (4.8 million) Australians aged 16 to 85 had a current and chronic mental health or behavioural condition[vi]. This number has been steadily increasing, up nearly 3% from the 2014-15 National Health Survey. At least 45%[vii] of Australians will experience a mental illness in their lifetime[viii].
The most common mental illnesses in Australia are depression, anxiety, and substance use disorders (often occurring together). In a single year, 13% of Australians will be diagnosed with an anxiety-related condition (e.g., post-traumatic stress disorder, social phobia), 10% with a depression-related condition[vi], and over 5% of Australian adults generally[ix], and 13% of people aged 16-24, will be diagnosed with a substance use disorder[x]. Diagnoses aside, in 2017-18, 13% (2.4 million) of Australians reported high or very high levels of psychosocial distress over the past 4 weeks alone[vi].
Mental illness in Australia – Harms
In 2011, mental illness was responsible for 12% of the total disease burden in Australia (years of life lost and years of life lived with disability, combined), behind only cancer and cardiovascular disease[xi]. When considering only years lived with disability (non-fatal disease burden), mental illness was the leading cause.
An estimated 200 Australians attempt to take their life each day[xii], and the suicide rate in Australia has been steadily on the rise over the past decade. Suicide is the 13th leading cause of death – over 3,000 Australians take their life each year, or 8-9 people each day[xiii]. The more prevalent causes of death are attributable to factors largely associated with old age, with median ages of death for these causes typically in the 80s – the median age for suicide is 45 years. Mood disorders (including depression and anxiety) are the leading cause of suicide, accounting for 43% of Australian suicides in 2017-18[xiii].
Mental Illness in Australia – Costs
Mental Illness Treatment
To date, psychedelic-assisted psychotherapy research has shown early yet strong clinical results, particularly for disorders of depression, anxiety, addiction, and obsession. Psychedelics and MDMA are incredibly safe compared to other substances. MDMA-assisted psychotherapy (not a classical psychedelic, but associated with various ‘psychedelic effects’ and often discussed among the classical psychedelics) has shown promise for treating Post-Traumatic Stress Disorder. Psychedelics and MDMA are incredibly safe compared to other substances (See figure 4).
