Developing a workplace drug and alcohol policy is an important step in managing health, safety and fitness-for-work risks. These frequently asked questions explain what Australian employers need to know about workplace drug testing, employee responsibilities, testing procedures, Australian Standards, policy requirements and managing positive drug or alcohol test results in the workplace.
1. Why does my workplace need a drug and alcohol policy?
A workplace drug and alcohol policy helps employers manage health and safety risks associated with alcohol, illicit drugs, prescription medications, and other substances that may impair a worker's ability to perform their job safely. A clear policy demonstrates a commitment to maintaining a safe workplace and meeting workplace health and safety obligations.
2. Is a workplace drug and alcohol policy a legal requirement in Australia?
While most Australian workplaces are not legally required to have a drug and alcohol policy, employers have a duty to provide a safe workplace. For many organisations, a drug and alcohol policy is an important risk management tool that helps meet these obligations.
3. Which workplaces should have a drug and alcohol policy?
Every workplace can benefit from a drug and alcohol policy. However, policies are particularly important in high-risk industries such as mining, construction, transport, manufacturing, aviation, logistics, utilities, and heavy vehicle operations.
4. What should be included in a workplace drug and alcohol policy?
A comprehensive policy should include:
- Purpose and objectives
- Scope of application
- Roles and responsibilities
- Fitness for work requirements
- Drug and alcohol testing procedures
- Incident reporting procedures
- Management of positive results
- Confidentiality requirements
- Support and rehabilitation options
- Disciplinary procedures
5. Can an employer conduct workplace drug and alcohol testing?
Yes, drug and alcohol testing may be performed in-house rather than outsourced as long as the collector is trained in the course HLTPAT010 Collect specimens for drugs of abuse testing.
In many workplaces, drug and alcohol testing can be implemented as part of a broader risk management program. Testing should be supported by a documented policy, consultation with workers, and a workplace risk assessment.
6. What types of workplace drug testing can be included in a policy?
A policy may include:
- Pre-employment testing
- Random testing
- Post-incident testing
- Reasonable cause testing
- Return-to-work testing
- Follow-up testing
The testing program should reflect the level of risk within the workplace.
7. What is "fitness for work"?
Fitness for work means a worker is physically, mentally, and medically capable of performing their duties safely without posing a risk to themselves or others.
8. Can prescription medications affect fitness for work?
Yes. Prescription and over-the-counter medications may cause drowsiness, impaired judgement, slower reaction times, or reduced concentration. Workers should notify their employer if a medication could affect their ability to work safely.
9. Does a worker have to disclose their medical condition?
Generally, workers do not need to disclose their medical diagnosis. However, they may be required to inform their employer if medication or treatment could impact workplace safety.
10. Can an employee refuse a drug or alcohol test?
Yes, however, consequences of refusing a test should be clearly outlined in the workplace policy. In most cases refusal is deemed a 'non-negative' test and results in termination of employment.
Employers should seek legal or industrial relations advice when developing testing procedures and refusal provisions.
11. What is reasonable cause or reasonable suspicion testing?
Reasonable cause testing occurs when a worker displays signs that may indicate impairment, such as:
- Slurred speech
- Unsteady movements
- Poor coordination
- Unusual behaviour
- Smell of alcohol
- Significant changes in performance or concentration
12. What should a supervisor do if they suspect a worker is impaired?
The supervisor should prioritise safety, remove the worker from safety-sensitive duties if necessary, document observations, and follow the procedures outlined in the workplace drug and alcohol policy.
13. Can a worker be disciplined for a positive drug test?
The outcome will depend on the workplace policy, employment agreements, the circumstances of the result, and whether the worker poses a safety risk. Positive test management procedures should be clearly documented.
14. Should a workplace offer rehabilitation and support?
Many organisations include counselling, Employee Assistance Programs (EAPs), rehabilitation referrals, and return-to-work support as part of their drug and alcohol management framework.
15. What is the difference between impairment and detection?
A drug test detects the presence of a substance or its metabolites. A positive result does not automatically prove impairment at the time of testing. This distinction should be understood by both employers and employees. A saliva drug test tests for impairment while a urine drug test detects recent use.
16. How often should a workplace drug and alcohol policy be reviewed?
Policies should generally be reviewed every two to three years, or sooner if there are legislative changes, workplace incidents, changes to operations, or updates to Australian Standards.
17. Should contractors be covered by the drug and alcohol policy?
Yes. Contractors, subcontractors, labour hire workers, visitors, and other persons performing work on behalf of the organisation should be included where appropriate.
18. What Australian Standards should be referenced in a workplace drug testing policy?
Current Australian Standards include:
- AS/NZS 4308:2023 for urine drug testing
- AS/NZS 4760:2019 for oral fluid (saliva) drug testing
- AS 3547.1:2019 for breath alcohol testing devices
Using Australian Standard-compliant testing methods helps improve consistency and legal defensibility.
19. What records should be kept under a drug and alcohol policy?
Employers should maintain confidential records relating to:
- Testing procedures
- Training records
- Incident reports
- Consent forms
- Test results
- Policy reviews
Privacy and confidentiality obligations must always be maintained.
20. What are the benefits of having a workplace drug and alcohol policy?
An effective policy can help:
- Reduce workplace incidents and injuries
- Improve workplace safety
- Increase productivity
- Support worker wellbeing
- Reduce absenteeism
- Demonstrate compliance with WHS obligations
- Create a safer and more accountable workplace culture
