Aims. To present the prevalence of substance use and ICD-10 substance use d
isorders in the adult Australian population using data from the National Su
rvey of Mental Health and Well-Being (NSMHWB). Design. A cross-sectional su
rvey assessing substance use and ICD substance use disorders (harmful use a
nd dependence). Setting and participants. A household survey of a nationall
y representative sample of 10 641 Australian adults (aged 18 years or older
). Measurements. Trained survey interviewers administered a structured inte
rview based on the Composite International Diagnostic Interview (CIDI). Fin
dings. In the past 12 months 6.5% of the sample had an ICD-IO alcohol use d
isorder (95% CI: 62, 6.9), and 2.2% had another drug use disorder (95% CI:
2.0, 2.4). More males than females had substance use disorders: 9.5% of mal
es (95% CI: 8.5, 10.5) and 3.6% of females (95% CI: 3.2, 4.0) met criteria
for an alcohol use disorder, and 3.2% of males (95% CI: 2.8, 3.6) and 1.3%
of females (95% CI: 0.9, 1.7) met criteria for another drug use disorder wi
thin the past 12 months. The prevalence of substance use disorders decrease
d with increasing age: 10.5% of respondents aged 18-34 years met criteria f
or an alcohol use disorder and 4.8% met criteria for a drug use disorder. T
he rates of these disorders among those aged 55 years or older were 1.8% an
d 0.1%, respectively. Substance use disorders were more prevalent among the
