Drug use in Australia: a community prevalence study

Area of Science:

• Epidemiology
• Public Health
• Substance Abuse Research

Background:

• Community-based studies are crucial for understanding drug use patterns.
• Existing routine data sources for drug use epidemiology are often inadequate.
• Representative surveys are needed to accurately estimate drug consumption in the general population.

Purpose of the Study:

• To determine the prevalence of various drug types used in a representative Australian community.
• To identify demographic differences in drug consumption patterns.
• To highlight the need for ongoing, comparable community drug use research.

Main Methods:

• A representative sample of dwellings was selected using a Census district sampling framework.
• Data were collected through a large-scale general population health survey in Greater Newcastle, NSW, during 1987-1988.
• 72% of eligible individuals (2623) participated, reporting on use of prescribed drugs, non-prescription drugs, tobacco, alcohol (hazardous level), and illicit drugs.

Main Results:

• 78% of the community sample reported recent use of at least one drug type (95% CI: 76%-80%).
• Significant age and sex variations in drug use were observed.
• Women and older adults (over 45) were more likely to use prescription and non-prescription medications, while men and younger adults reported higher use of social and illicit drugs.

Conclusions:

• Regular, methodologically comparable community studies on drug use are essential.
• Findings underscore the limitations of current routine epidemiological data for drug use.
• This research emphasizes the value of population-based surveys for accurate drug use assessment.
