What is the role of the Illicit Drug Reporting system in Australia?
It is Australia’s central monitoring and early warning system which identifies key and emerging trends among injecting drug users
What does the National Drug and Alcohol Reporting System comprise of?
- nearly 1,000 interviews with injecting drug users across Australia
- interviews with key experts who work in the drug and alcohol sector.
- incorporates analysis of other national data related to illicit drug use in Australia.

Average age of first injection was age 20
Poly drug use was high - varied markedly across states.
Nearly two thirds of Australia’s injecting drug users inject some form of methamphetamine (lowered frequently)
Morphine was the most commonly used prescription opioid; the majority of that obtained illicitly. Recent oxycodone was high
Methamphetamine and cannabis (daily) were the most commonly used drugs alongside heroin.

What is involved in the intervention of psychoeducation in IVDU?
education about: Risk taking (injecting, sex, intoxication) Safer injecting Vein care Overdose Community safety/disposal
what did Westermeyer & Boedicker (2000) study?
“Course, severity and treatment of substance abuse among women verus men”…
what was involved in Westmeyer & Boedicker’s (2000) study?
Retrospective data analysis: 642 patients (43% women) from university medical program a&d programs (USA)
Data: demographics, family history, patterns of use++, periods of abstinence, current diagnosis
Comparisons were made between women and men
What were the results in Westmeyer & Boedicker’s (2000) study that women were…?
Women were…
More likely to be “homemakers” (unemployed)
More likely to have a substance-abusing spouse (if married)
Less likely to have legal problems associated with substance misuse
Less likely to report lifetime use of inhalants or hallucinogens
Less likely to be cannabis-dependent
More likely to have used substances for fewer years (shorter time period)
What were the results in Westmeyer & Boedicker’s (2000) study that women reported…?
Fewer admissions for treatment
Fewer treatment days (when admitted)
Lower overall treatment costs Implications regarding a “male-orientated” treatment system
Consistent with previous research, what did Westmeyer & Boedicker (2000) suggest women have?
A more rapid course (time frame) for developing substance problems
More commonly have a substance-abusing partner
Reduced treatment options/patterns
What are the biological differences for women?
Intoxication occurs with less alcohol intake
Metabolise alcohol differently
Develop cirrhosis of the liver more rapidly
What are the social differences for women?

More often caring for children
Cultural differences regarding status in society
what are the patterns of use for women?
Develop problematic use more quickly
More use of prescription medications
More “private” use/misuse
What is there limited research on regarding women?
Lack of research regarding women
Conclusions drawn with men may not adequately generalise to women
Impacts prevention and treatment developments
