Morbidity and mortality
There is currently no systematic collection of inhalant-associated mortality or morbidity at either a national or state/territory level in Australia (d’Abbs & MacLean, 2008). One reason is the range of methodological issues associated with the assessment of morbidity and mortality associated with VSU.
For example, volatile substance users may present to hospitals or clinics with illness such as pneumonia or injury such as burns which have volatile substance inhalation as an underlying cause and are therefore not recorded as being associated with VSU (d’Abbs & MacLean, 2008).
Data collected by the WA Department of Health shows that volatile substance-related hospitalisations accounted for 0.7% of all drug-related hospitalisations between 2012 and 2016.

- The average number of volatile substance-related hospitalisations in WA was 46 persons per year between 2012 and 2016 inclusive.
- Of the hospitalisations for the combined population, 61.8% were male
The following table shows the percentage of volatile substance-related hospitalisations by age and sex (State: 2012 to 2016).

- The age group most frequently hospitalised due to VSU is 25-44 year olds.
- Although the total number of volatile substance-related hospitalisations in males was greater than the number of female hospitalisations, the percentage of males aged 25-44 years affected was lower than that seen for females in WA.
According to the Western Australia Mortality Database (2005-2015), there have been a total of 14 deaths attributed to volatile substance use from 2006 to 2015. Of these deaths, the majority (64%) were Aboriginal and 9 out of the 14 deaths were male.
While there is no systematic Australian mortality data, the United Kingdom has been collecting data about VSU-related mortality since 1971. This provides insight into patterns and prevalence of use and cause of death. For example, it has repeatedly revealed that the majority of VSU-related deaths are from the inhalation of butane gas and aerosols and the most common methods of administration of gas fuels causing fatalities are from inhaling directly into the mouth followed by the use of a plastic bag over the head. The data also identifies that the principal mechanism of death for VSU was attributed to the direct toxic effect of the substance used.
Despite the different cultural context in which this research was conducted, the UK’s systematic collection of data over 30 years can provide some insight into VSU in Australia. For more information, see Trends in UK deaths associated with abuse of volatile substances 1971–2009.
