Policy framework
Drug use in Australia
Alcohol and tobacco are 2 of the most widely used drugs in Australia. The most recent 2022–2023 National Drug Strategy Household Survey reported that of people aged 14 and over in Australia:
- 8.3% smoked tobacco daily.
- 77% consumed an alcoholic drink in the previous 12 months.
About 1 in 3 (31% or 6.6 million) people aged 14 and over consumed alcohol in ways that put their health at risk according to the Australian Alcohol Guidelines (drinking more than 10 standard drinks per week on average or more than four standard drinks in a single day at least once a month; NHMRC 2020). This was similar to 2019, when 32% of the population (around 6.7 million people) reported drinking at risky levels (AIHW 2024a).
In 2022–2023, illicit drug use was relatively common among people aged 14 and over in Australia:
- 47% self-reported they had illicitly used a drug at some point in their life (including pharmaceuticals used for non‑medical purposes) and 17.9% had done so in the last 12 months.
- Cannabis continued to be the most commonly used illicit drug with more than 2 in 5 (41%) having used it in their lifetime and 11.5% using it in the previous 12 months.
- Ecstasy and cocaine were the second and third most common illicit drugs used in a lifetime (13.6% and 13.5%, respectively) and in the last 12 months (2.1% and 4.5%, respectively) (AIHW 2024a).
Health impacts
Tobacco, alcohol, and illicit drug use contribute to increased chronic disease, injury, poisoning and premature death and are among the leading risk factors contributing to the total disease burden in Australia. Together tobacco, alcohol and illicit drug use accounted for 14% of the total burden of disease in Australia in 2024 (AIHW 2024c).
Social impacts
The social impacts of AOD use in Australia include involvement in criminal activity, engagement in risky behaviours, victimisation and road trauma. In 2019, 1 in 5 (21%) people in Australia aged 14 and over were victims of an alcohol-related incident and 10.5% were victims of an illicit drug-related incident (AIHW 2020). This trend continued in 2022–2023, where 1 in 5 people (21%) aged 14 and over were victims of alcohol-related incidents and 1 in 10 people (10.1%) were victims of illicit drug-related incidents. Alcohol and illicit drug related incidents include verbal abuse, physical abuse, or being put in fear by someone under the influence of a substance in the previous 12 months (AIHW 2024).
Economic impacts
The use and non-prescribed use of licit and illicit drugs imposes a heavy financial cost on the Australian community. In 2022–23, the projected separate costs of tobacco ($159.7 billion), opioid ($18.4 billion), methamphetamine (over $6 billion) and alcohol use ($74.9 billion) in Australia have been estimated, utilising different methodologies (Gadsden et al. 2023).
The National Drug Strategy
Australia has had a coordinated approach to dealing with alcohol and other drugs since 1985. The National Drug Strategy (NDS) 2017–2026 is the 7th and latest iteration of the cooperative strategy between the Australian Government, state and territory governments, and the non-government sector. The NDS provides a framework that identifies national priorities relating to alcohol, tobacco and other drugs, guides action by governments – in partnership with service providers and the community – and outlines a national commitment to harm minimisation through balanced adoption of effective demand, supply, and harm reduction strategies.
The objective of the National Drug Strategy
The NDS has an overarching approach of harm minimisation and encompasses 3 pillars, each with specific objectives (NDSC 2017):
- demand reduction
- to prevent the uptake and/or delay the onset of use of alcohol, tobacco, and other drugs
- to reduce the use and harms of alcohol, tobacco, and other drugs in the community
- support people to recover from dependence through evidence-informed treatment
- supply reduction
- to prevent, stop, disrupt, or otherwise reduce the production and supply of illegal drugs
- to control, manage, and/or regulate the availability of illegal drugs
- harm reduction
- to reduce the adverse health, social and economic consequences of the use of drugs for consumers, their families, and the wider community.
The collection of treatment services data, for example in the Alcohol and Other Drug Treatment Services National Minimum Data Set (AODTS NMDS), forms part of the evidence base reinforcing harm reduction actions in the strategy, which include (NDSC 2017):
- increasing access to pharmacotherapy treatment to reduce drug dependence and reduce the health, social, and economic harms to individuals and the community that arise from use of opioids
- monitoring emerging drug issues to provide advice to the health, law enforcement, education, and social services sectors to inform individuals and the community regarding risky behaviours
- developing and promoting culturally appropriate alcohol, tobacco, and other drug information and support resources for individuals, families, communities, and professionals in contact with people at increased risk of harm from alcohol, tobacco, and other drugs
- providing opportunities for intervention among high-prevalence or high-risk groups and locations, including the implementation of settings-based approaches to modify risk behaviours
- enhancing systems to facilitate greater diversion into health interventions from the criminal justice system, particularly for Aboriginal and Torres Strait Islander people, young people, and other at-risk populations who may be experiencing disproportionate harm.
Alcohol and other drug treatment services
AOD treatment services provide support to people regarding their use of alcohol or drugs through a range of treatments. Treatment objectives can include reduction or cessation of substance use, as well as improving social and personal functioning. Treatment and assistance may also be provided to support the family and friends of people who use alcohol or other drugs. Treatment services include detoxification and rehabilitation, counselling, and pharmacotherapy, and are delivered in residential and non-residential settings.
In Australia, publicly funded treatment services for AOD use are available in all states and territories. Most of these services are funded by state and territory governments, while some are funded by the Australian Government. Information on publicly funded AOD treatment services in Australia, clients, and drug treatment are collected through the AODTS NMDS. The AODTS NMDS is one of several national minimum data sets that collect data under the 
2012 National Healthcare Agreement to inform policy and help improve service delivery (COAG 2012).
Other available data sources that support a more complete picture of AOD treatment in Australia include:
- the National Opioid Pharmacotherapy Statistics Annual Data collection
- the National Hospital Morbidity Database
- the Specialist Homelessness Services collection
- the National Prisoner Health Data collection.
The Alcohol and Other Drug Treatment Services National Minimum Data Set
The Alcohol and Other Drug Treatment Services National Minimum Data Set (AODTS NMDS) contains information on treatment provided to clients by publicly funded AOD treatment services, including government and non-government organisations. Information on clients and treatment services are included in the AODTS NMDS when a treatment episode provided to a client is closed (see Key terminology and glossary). This is a service-based collection and not a demand-based collection, noting that services are limited by the number of clients they are able to provide treatment to, and that this may not be reflective of the demand for services by the broader community.
Information on the following types of treatment are reported:
- assessment only
- counselling
- information and education
- pharmacotherapy
- rehabilitation
- support and case management
- withdrawal management
- other (see Key terminology and glossary).
The AODTS NMDS collects data about services provided to people who are seeking assistance for their own alcohol or drug use and those seeking assistance for someone else’s alcohol or drug use.
Client information is collected at the episode level in the AODTS NMDS. Further details on the estimation of client numbers and the imputation methodology can be found in data and methods.
Data collected by treatment agencies are forwarded to the relevant state and territory health departments, who then extract required data according to the specifications in the AODTS NMDS. Data are submitted to the Australian Institute of Health and Welfare (AIHW) annually for national collation and reporting.
Coverage and data quality
Although the AODTS NMDS collection covers the majority of publicly funded AOD treatment services, including government and non-government organisations, it is difficult to fully quantify the scope of AOD services in Australia.
The current scope of the collection includes:
- All publicly funded (state, territory or Australian Government level) government and non-government agencies that provide one or more specialist alcohol and other drug treatment services, whether residential or non-residential.
- Acute care hospitals or psychiatric hospitals if they have specialist alcohol and other drug units that provide treatment to non-admitted patients (for example, outpatient services).
- Aboriginal or mental health services if they provide specialist alcohol and other drug treatment.
People receive treatment for alcohol and other drug-related use in a variety of settings not in scope for the AODTS NMDS. Excluded settings include:
- services provided by other not-for-profit organisations and private treatment agencies that do not receive public funding
- alcohol and other drug treatment units in acute care or psychiatric hospitals that provide treatment only to admitted patients
- prisons, correctional facilities and detention centres
- primary health-care services, including general practitioner settings, community-based care, Indigenous Australian-specific primary health-care services and dedicated substance use services
- health promotion services (for example, needle and syringe programs)
- accommodation services (for example, halfway houses and sobering-up shelters) (Figure AODTS1).
In addition, agencies whose sole function is prescribing or providing dosing services for opioid pharmacotherapy are excluded from the AODTS NMDS. These data are captured in the AIHW’s National Opioid Pharmacotherapy Statistics Annual Data collection.
